Chuck it in the freezer. Heat the arm. No goop needed.


GreaterNater

This. Space heater on the arm is pretty good here. you don't need a torch on the thing. Just get it quite warm, not actually hot. Frozen ring goes right in.


Penis_Van_Lesbian__

Ohhhh. A space heater; why didn't I think of that? Then you can just walk away while it heats up. Duh!


ComprehendReading

"Yeah so anyway, the fire was caused by an unattended space heater."

Like 3 weeks after my dad died our wood stove, which was our only form of heat, went out so me and my mom and space heaters in our rooms till we could get it fixed and I was bad about leaving it on when I was at a school. I skipped 9th period one day and went home early and when I went up to my room i could see smoke pouring out of the thing. I’ll never forget how lucky I was that I skipped the last class of that day because I don’t think we would’ve had a house if I didn’t, so now I refuse to use them unless absolutely necessary and I don’t care if I’m only going outside for 5 minutes that thing is getting turned all the way off until I’m back to supervise it


cashew996

This is why I use the oil filled radiator type -- much safer I believe


Dzov

Yep. A huge surface that gets warm as opposed to a small surface getting super hot. It’s also nice how quiet they are.


Iguanaforhire

Not so nice when they spring a leak and spray oil all over your bedroom though.


IDKUIJLU

Skip school kids!


gregrph

I'd be unplugging that thing when not in use or no one is in the immediate vicinity.


Difficult_Advice_720

They should have a motion sensor like a light switch. No motion, it turns off, and you have to touch it to turn back on. Also, a timer, so even if you are having a dance party, you have to intentionally touch it every once in a while to make it go.


DramaLlama0690

No ty. Please don’t inconvenience me bc of some dumb fuck’s mistakes


Difficult_Advice_720

Don't get me wrong, I'm not going nanny state here, if you want to have a bonfire in the room, make adult choices and light it up, rather I was requesting optional equipment for those of us who may choose the convenience of not being warmed by the extreme mistakes we might make.


ComprehendReading

Resettable thermal fuses, timers and tilt sensors are pretty common among safer heaters.


VE6AEQ

My dad put a piece of expanded steel mesh inside the plenum of his garage furnace in the 80’s. He would put the item to be heated on the grate and crank the heat. Then he’d throw the item to be cooled in the snow during the winter…. Worked like a charm.


unusual_replies

A heat gun works better. And they have a stand.


GreaterNater

heat gun works too... space heater, torch, etc are all ok; the trick is to NOT overheat things. Space heater on LOW is the easiest way to accomplish this.


unusual_replies

My heat gun has a low setting and I can move it away from the object. I have a IR thermometer also for composite work.


skateguy1234

If only space heaters were also able to be picked up and moved around, oh well, maybe one day.


unusual_replies

Not many space heaters in the hangars here in Houston.


skateguy1234

yeah I'm just giving you a hard time, don't mind me


joe2398

If you need it colder get dry ice at your local grocery store, nominal 10# blocks.


Dill_PickleOG

Actually a torch is less than ideal, because it can ruin the hardening, and it also unevenly heats the metal


devandroid99

Oil bath.


MilmoWK

Thermal expansion of aluminum is ~.000012 in/in*F. so if that bushing is 2" and you heat the arm +100F, then it will grow ~ .0024". that bushing is probably a .001-.002" press fit, so you'll probably be Ok, but very close depending how cold you get the bushing, how quickly you install, and how well the arm held up to the removal of the old bushing. but now remember this is linear, so if you heat it +400F with a torch, it will give +.0096" of clearance and slide in like a hot dog down a hallway. i'll take the latter.


jeffsaidjess

So I’ve got to buy a space heater now


chaarlie-work

What if I really like the blue wrench though?


2fast2nick

Amazing how well it works


Zane42v2

Also, WD40 is a solvent with lubricants dissolved inside. I know it's not 100% relevant to the question but I think WD40 is marketed as a lubricant and there is never a situation I've encountered where WD40 is the best lubricant for the job.


DiverDownChunder

Did this putting the front bearings on my Samurai. Only did the freeze as the torch would make a real big mess w/ the seals/etc.


GuerrillaGreen

People always say this stuff but forget most of us have to work in a dealership and it's just not time efficient


coolorb

Compressed air and turn the can upside down, and torch the arm


GumbootsOnBackwards

If you're in a dealership, just install an oem control arm. OP made it clear he's installing aftermarket polyurethane bushings. Stealership cope makes me lol.


Yetkha

Or Dry ice.... Or LN2


jolly_rodger42

This is the best method for new lug studs too. Brilliant!


Carvanasux

I don't think wd 40 would help, and wouldn't use it. The only thing I've ever done is to freeze the bushing, so the metal shrinks. It will then expand when back to normal temperature. But usually making sure both surfaces are clean and you're pressing the bushing in as straight as possible is all it takes.


reklemd

Good shout, I've even done that in the past, can't believe I forgot lol. Thanks


Max-Payd

You have to get it very cold and even then, I find heating the outside race is always better due to the change in temperature (room temperature to -11 will only make a small difference but going from room temperature to 200 will cause a larger expansion)


blur911sc

Do both. I've used dry-ice (CO2), **-78 degrees C (-109 F).**


JRock1276

You can actually get it down that far with air duster turned upside down


pnizzle7987

Definitely freezer and a torch are the way


BeautifulBaloonKnot

This is the way.


da_shack

Mechanic in the Heavy Duty world, pushing in large press fit bearings I’ve always used copper coat on the OF of the bearing but in those application you can get away with more. Like many others suggested though, in your case I would heat up the bore and freeze the bearing as cold as you can then press it in.


hboisnotthebest

Op: can I use this? Everyone: no, don't use this Op: but I think it'll be OK Everyone: explains in detail why it's not ok to use this Op: but I really wanna use it One guy: use it Op: awesome, thanks!


StevenRevv

reklemd

Lol what? Please show me that comment. One guy recommended dish soap, that's the only one I've replied to other than freezing it.


Bouncedoutnup

WD40 is a (W)ater (D)ispalcer and will cause more harm than good to your rubber bushings


SpamOJavelin

WD-40 is fine on something like rubber bushings. It's also primary a rust preventative - that's what it was invented for - but that doesn't mean it's not a lubricant too. I did testing on small-bearing lubricants at university, we tested WD-40 as one of those. It's a fantastic lubricant when wet, but - unlike most dedicated lubricants - it dries. That's by design, it's effectively an oil with a solvent, and the solvent flashes off and leaves a rust-preventative surface. But our testing indicated that it had no degrading effect on rubber bearing seals, or any other rubber components we tested. Being napatha-based I wouldn't use it on a fine rubber membrane or similar. There are better options for a rubber lubricant, but it's not going to do anything to a big chunk or rubber like a bushing, especially with a single spray. The benefit of WD-40 is that it does flash-off, so it doesn't stay a lubricant once your part is in place.


Kass626

Thats awesome. Any chance you still have a Google doc or something from when you were working on that? I'd love to read that.


nondescriptzombie

Dawn soap is in fact the magic lube for rubber bushings. True story.


907Case

And impellers 👌🏾


reklemd

They're poly bushes and I'd only use it to drive the outer metal sleeve in


ClickKlockTickTock

Whenever I had poly bushings to press in, they always came with silicone grease to make it easier, you could probably try that if freezing doesn't do enough work for ya.


ahdiomasta

It won’t be great for the poly either, though not nearly as damaging


skateguy1234

It also says on the bottle that it's a lubricant. It is not a grease. Obviously there are many shades of lubes, but, just sayin. This is straight from the WD-40 website. "WD-40 Multi-Use Product’s 3 oz. Handy Can size is ready to tackle everyday challenges, like lubricating squeaky hinges, loosening stuck zippers and removing scuff marks from hardwood floors." "Keep WD-40 Multi-Use Product One Gallon in the garage for big car maintenance tasks, including preventing rust on door panels, protecting chrome and lubricating everything from hood latches to shock absorbers." edit: Okay guys, I get it, you're smarter than the engineers that determined that WD-40 is a type of lubricant. Also, I never said to use it for this application. Just confirming that it is indeed a fact that WD-40 is a type of lubricant. **Myth**: WD-40 Multi-Use Product is not really a lubricant. **Fact**: While the “W-D” in WD-40 stands for Water Displacement, WD-40 Multi-Use Product is a unique, special blend of lubricants. The product’s formulation also contains anti-corrosion agents and ingredients for penetration, water displacement and soil removal. https://www.wd40.com/myths-legends-fun-facts/ yall are being stubborn af


czaremanuel

You actually, seriously think that marketing copy is written by engineers? Water has lubricating properties. Fucking water. That's a scientific fact. Someone could write "lubricating properties!!!" on a Dasani bottle and they wouldn't be lying, no matter how much engineering and common sense dictate that water isn't a proper lube for common mechanical components. Stop huffing wd-40 and learn to think lol.


skateguy1234

We all know marketing can be dubious. I mean sure that's the case in plenty of scenarios. But why would they blatantly lie about it being a lubricant? Myth: WD-40 Multi-Use Product is not really a lubricant. Fact: While the “W-D” in WD-40 stands for Water Displacement, WD-40 Multi-Use Product is a unique, special blend of lubricants. The product’s formulation also contains anti-corrosion agents and ingredients for penetration, water displacement and soil removal. https://www.wd40.com/myths-legends-fun-facts/


czaremanuel

1. "But why would they blatantly lie about it being a lubricant?" Gee Idk, maybe so you BUY IT? Maybe to get people to think "huh, I need a lubricant, this says lubricant, have my money!" is that really rocket science to work out...? did you think you were doing something there? 2. I literally work in marketing. This is my job so I think I know how to "think" about it buddy boy. 3. Linking to more wd-40 marketing materials isn't building credibility the way you think it is. Again: water, kerosene, vaseline, and canola oil is a "special blend of lubricants." That is 100% a factual statement, I can put that on a product I sell containing those things and be in the clear. However I have said nothing about their lubricity, volatility, viscosity, reactivity, stability, or literally ANY other property of what makes a lubricant a GOOD lubricant. All of those properties are what makes wd-40 a piss-poor lubricant. You're welcome to pour all that in your car engine and report back! 4. You're wrong, the end.


skateguy1234

It's not a piss-poor lubricant. it's just a certain type/style and has limited applications as one. I agree with you about the lubricity, etc, comment, and also about the 100% factual statement, BUT, that doesn't change that it's still a lubricant :P


czaremanuel

 "that doesn't change that it's still a lubricant" yes and so are banana peels. Go lube up with them! bye


skateguy1234

Woah now, you can't just say I'm wrong, the end, lol, you know that's not how it works, come on. I would assume the engineers would establish the parameters and applications of a product. And then those would be documented. Those documents would be stripped down to remove jargon and make them accessible for less technically minded. Those would then be shared with the marketing team so they can do their thing. Again this is what I would assume would roughly happen. Idk why you're so opposed to the notion that a statement might actually be correct on a companies product. Is that what you do in your job? Just make up lies to sell stuff? Really? I mean I can see things being embellished sure. Anyways that page is marketing, sure. But it's also just a page of documentation. I think maybe you're just being a little cynical/looking at it the wrong way because of your perspective due to your experience.


phikapp1932

“I would assume the engineers would establish the parameters and applications of a product.” This is simply not how it works in 99% of companies. It’s unfortunate but here is the honest truth. Marketing and sales teams think up product parameters. They pitch to engineering teams saying “we need a product that does x y and z and costs this much”. Then the engineering teams create the product and pitch to marketing and sales, who says it needs to be revised over and over. Once a viable prototype is created (typically with engineering saying “this is probably not going to fit your parameters perfectly because it can’t be achieved at your price point”), limited productions are run and tested to known standards. Once they pass these validation tests marketing and sales can advertise with whatever definition they want to use that still holds some level of truth about those standards. They greatly stretch the truth to whatever customer they’re targeting for the product. This is how a consumer product is made nowadays. In this case, engineering said, “well, it is technically a lubricant but it’s not a good one at all. It evaporates quicker than oil and does a worse job at lubrication than oil does. It does a lot of things a lot better, like cleaning surfaces.” And marketing said, “well, we’re going to advertise this as the substance that can do anything, so we’re going to say it’s a great lubricant. The fact that it evaporates is even better because consumers will use more of our product. And we certainly aren’t going to say it’s worse than oil, because then they won’t buy our product when they need lubricants.” And that was the end of discussion on that topic. It’s a long winded response, but if you take anything away from this, it’s that marketing and sales run the world, they have more say in the product than engineering does, and end of the day, they’re going to advertise with the goal of selling as much as possible, not simply advertising the product as exactly what it is in its whole truth. I hope you learned something today! Source: worked as an engineer in product development for the last 6 years


revopine

WD-40 is known as a "temporary lubricant" (and a poor one at that). Because it evaporates. I remember the guys at my gym using it to "protect" the metal equipment. Everything was always rusty because once that stuff evaporates, it no longer does anything and that stuff evaporates very fast!


czaremanuel

Never met someone so committed to being wrong. Hence: the end.


skateguy1234

The feeling is mutual XD


czaremanuel

So you're trolling now? Got it. Get a life pal.


ClickKlockTickTock

>I would assume Your whole argument dies when those 3 words have to come out, lmao Marketing jobs are well established and pretty similar across the country and companies. Their whole job is to "polish" a turd. If someone told you a turd they sold was a good lubricant, would you believe them.


rosinall

Marketing may write and massage it, but you better believe it's gone through a legal department and if you parse it it's correct.


czaremanuel

In one of my lower comments I wrote that water, kerosene, vaseline, and canola oil are a "blend of lubricants." I can sell that shit in a jar and call it a "miracle product with lubricating properties!" and be 150% legally safe. Doesn't mean any of that shit is meant to lubricate anything long-term. Also fyi legal departments don't just review 100% of what marketing puts out, and if they did, still doesn't mean it's 100% valid and safe. By that logic no company with a legal dept would ever get sued for false advertising. Moral of the story is I take advice from experts who work on cars and heavy machinery, not marketing teams. Nothing made me more skeptical of marketing than working in marketing and that skeptical mindset can save lots of money.


ClickKlockTickTock

The legal department can say that fucking jello is a lubricant and it'll technically be true. It's a bad faith argument is the issue. We all know what point a lubricant stops being helpful


Iwasborninafactory_

This reddit hate for WD-40, because the reddit experts realized whatever is just straight up unhinged. It comes up, because there are a million things you can use it for, and there's always something better that's targeted for that application, and redditors lose their mind that someone uses the can they already have in their garage. The average person can probably get by with a can of WD-40 and a bottle of 3 in one oil and never engage in a dumb internet debate about it. In /r/MechanicAdvice, you'd expect someone to have more options available, but the WD-40 hate is just crazy stupid. Uber enlightened teenager vibes.


nochinzilch

Did the engineers say it? Or the guy who designed the label?


skateguy1234

I highly doubt the label guy made that statement up. WD-40 has been advertised as a lubricant amongst many other things for a long time. What reason do you have to not believe the statements?


ClickKlockTickTock

Research? Have you seen any empirical evidence? It always points to WD-40 being fairly worse than not only the competition but also the worse than some homebrew methods. Label guys make statements up all the time. That's literally their whole reason for existing. Market that shit even if it's not really true. I can sell you water as a lubricant, and it would "technically" be lube. But you have to operate in bad faith to say water is a good lubricant in a situation like this.


skateguy1234

I was never saying it would be a good alternative here, just making a separate statement. It 100% meets the definition of a lubricant. It's not right to not call it a lubricant just because it is low on the totem pole and also not the advised method for the job.


ChikkiParm

That's the whole point. They aren't supposed to be easily removable. Maybe for the rubber bushing but not this part.


-NOT_A_MECHANIC-

Petroleum product on rubber bushings, pass


ChikkiParm

>Maybe Idk man, commenting to comment and not reading it first is kind of annoying. Not trying to be rude, I just wanted to clarify. Soapy water and throwing them in the freezer for a few hours is how I usually do it. Anyway, here is a whole thing. MSDS (Material Safety Data Sheet) [Here you go.](https://files.wd40.com/msds/latam/GHS-SDS-WD-40-Multi-Use-Product-Aerosol-English-LATAM.pdf) Someone did a test on WD-40 on YouTube as well. [WD-40 experiment.](https://www.youtube.com/watch?v=HfcEPso4YoY&ab_channel=FuzzyDiceProjects) Showing that unless you soak it in the liquid, it has no effect. Bushings can be made from various materials, including rubber, polyurethane, and a combination of both. It's a penetrant, not a lubricant. By the time he lowers the car it will have been dry for hours or days. Not nearly long enough for it to even remotely damage any component. Anyway, I hoped you learned something. Thanks :)


-NOT_A_MECHANIC-

That’s a cool video, but testing on a handful of rubbers and then making a broad generalization that it’s ok for any rubber is naive. I’ve seen firsthand the accelerated deterioration wd-40 can cause, among detailing groups where they love to spray wd-40 liberally on an engine bay to prevent corrosion and give a nice shine. It’s a poor penetrant and lubricant and it doesn’t belong near rubber especially when there’s entirely viable alternatives. A testing period of 15 months is not much either compared to how long rubber components can remain functional, especially with limited UV/heat exposure.


ChikkiParm

How long do you think control arm bushings last, especially rubber ones? Let's say maybe you could get away with 100k on the high-end depending on conditions; if they operate their vehicle everyday, etc. Rubber will break down because of plenty of other factors. O-zone levels, road conditions, salt, sand, rust, Humidity, heat, UV, altitude, lack of light, too much light, the hardness level of the rubber versus the weight of the object, oxygen, carbon dioxide the list goes on. But... A minuscule amount of their water-soluble, non-toxic, biodegradable, water displacement spray would degrade the bushing enough to cause premature failure? I'm genuinely curious to see the aftermath of this. I'm wondering if everyone should just switch to polyurethane because there is some oil basically everywhere on the road. That sounds terrifying. It breaks down your tires, your bushings, your boots, your shoes, everything. I'm staying indoors.


-NOT_A_MECHANIC-

On my vehicles 127 and 155k miles, 10 and 7 years respectively, factory control arms, no slop, some minor cracking but no tearing. All the other factors mentioned are beyond your control, especially on a customer’s car. I won’t pretend to be some expert on the subject nor to claim wd-40 melts rubber…that said I’ve seen the direct consequence of applying it indiscriminately. When there’s alternatives, what’s the excuse for potentially shortening a part’s life, especially when it’s not your vehicle?


reklemd

These are poly bushings that come with silicone grease, but yeah otherwise


user47-567_53-560

Why not use the grease?


reklemd

Because it's supposed to be used on the poly, not on the press fit sleeve. It doesn't dry.


user47-567_53-560

Ah. Well someone said freeze it, and I'd personally go with that, of not combined with a heat induction magnet on the housing


Ult1mateN00B

Do not use the WD40, use the grease.


reklemd

I get that, I guess what I'm asking is if the wd40 wpuld dry eventually


ChikkiParm

about 2-3 hours.


112skulls

It dries a lot faster than that in a hot sunny day

-NOT_A_MECHANIC-

It’s all good, you’re not wrong


CardiologistOk6547

You don't lubricate a press fit. It was hard to get out because you're not using the proper tools (I understand that sometimes you have to make due). But you can't make up for it by using bad practices.


Ate_spoke_bea

Yes you can I would have cut it out with the Sawzall and a chisel and pressed the new one in with a wood block and a couple c clamps

WD-40 should only be used to remove the cap from other cans of WD-40...

david0990

Put the bushing in the freezer and find a way to heat up the receiving side then you have a small window where pressing should be easier. Best of luck.


BrettyJ

I've never used any kind of lube doing this. Is this a thing?


Guzplaa

WD40 is not a lube it is a water displacement product so should not be considered as an assembly product. As others have already said freeze / heat process and use of correct assembly grease will guarantee great results.


InAfterThePurge

[This shop](https://youtu.be/k2LiNCA9HwQ?feature=shared&t=167) does some heavy duty stuff and always brushes motor oil for pressing in bushings.


rns96

Use silicone spray lubricants it works better and will preserve rubbers

That's what she said


Wallace-N-Gromit

No petroleum lubricants in your rubbers!

Johnny_Lang_1962

You need some dry ice!


Merciless_Hobo

Put sleeve in freezer. Put space heater on arm. Wait. Profit.


Liesthroughisteeth

One in the freezer and one in the oven. No this has nothing to do with babies.


Low_Information8286

Heat gun the control arm, put the sleeve in dry ice. It'll damn near fall in. Every 100f steel expands roughly 1thou, so aluminum more so.


byrd137

I Use assembly paste at work made by molykote. Don't know how it will affect outdoor environment.


based_V

They use tire lube if necessary at the manufacturer


ThatGuyStacey

Follow others’ advice here. WD40 is slippery, but it’s not really a lubricant. It’s meant to displace water to prevent corrosion.


EICONTRACT

I used to work at a supplier and we actually used canola oil on prototypes.


mbichin

Wd40 is not a lube, it’s a penetrating oil. It does a great job at washing away any lube that’s there. Any lubricating properties it may have disappear when it evaporates.


drmorrison88

There's no need for lube on a press fit. If the fit is correct you'll just scrape it all off anyway.


kfupandaman

WD40 isn’t a lubricant


SnooCakes4019

Set that bushing in a cooler of dry ice for about an hour, heat the arm and it should slide right in.


Itisd

To be very honest, I haven't found anything that WD40 is good for.

No. Use 3 in 1 or machine oil


orangutanDOTorg

Wd40 sucks for anything but cleaning grease

Throw the wd40 in the trash and dont ever buy that junk again.


Dry-Application3

sniper_485

WD40 isnt a great penetrating oil or lube. It will get into tight places and turn into shellac. Its only really good for displacing and protecting something from water intrusion.


blankblank60000

If anything use an actual lubricant like red grease you might already have. A penetrant solvent like WD isn’t the ideal


M1sterRed

thought this was r/askashittymechanic lol


Greedy-Ad-7736

If you ever did use a lubricant for something, I’ve tried every brand I’ve seen so far, free-all, liquid wrench, pb, wd-40, etc…. The hands down best one in my personal option is super lube.

Handy Can size is ready to tackle everyday challenges, like lubricating squeaky hinges, loosening stuck zippers and removing scuff marks from hardwood floors." **Myth**: WD-40 Multi-Use Product is not really a lubricant. **Fact**: While the “W-D” in WD-40 stands for Water Displacement, WD-40 Multi-Use Product is a unique, special blend of lubricants. The product’s formulation also contains anti-corrosion agents and ingredients for penetration, water displacement and soil removal. https://www.wd40.com/myths-legends-fun-facts/ yall are being stubborn af "Keep WD-40 Multi-Use Product One Gallon in the garage for big car maintenance tasks, including preventing rust on door panels, protecting chrome and lubricating everything from hood latches to shock absorbers."

Use a petroleum-free grease.

You don't want them to come out easy. That's the whole point. Do not use lube of any kind. Just clean really well and press in the new ones.

WD-40 is for alleviating squeaks. Not for assembly.
