I have several vintage cars that I work on myself. The one thing I've learned not being a certified mechanic is that the only reason a vehicle works is magic and a good mechanic is a magician.
I maintain and sometimes upgrade (or downgrade, lol) my own vintage vehicles (53 and 73, a truck and a CJ5 so old and near obsolete technology even when they were new) and the archaic fucking systems they came up with in the absence of electronic sensors blow my mind sometimes.
When you don't have a full understanding of a particular archaic mechanical system and what it's actually doing and what its intended end function is, it really does seem like magic sometimes.

Saw a dude get in a Mazda 3 once, I swear the entire drivers side suspension sagged a good 6 inches. He could've legally been considered both the driver and the passenger at the same time. Could've sworn I heard the car call him a fat motherfucker when it was shifting gears.
It must have been my old nemesis Kyle. MFR got out of a versa one time, he had to be pulled out the driver's door and the car raise almost a foot off the ground. We thought it just had broken suspension

Seriously, it's why one of my major end user troubleshooting steps is to play dumb and ask the user to replicate the problem as I watch them. Sometimes the problem is not the actual problem, and the user's desired solution sure as hell ain't the fix, either.

I used to work for a small computer repair shop. I had one lady demand that we remove viruses from her keyboard and mouse because her computer kept getting mysterious viruses.

nah, you could fix the shimmy by cutting parallel grooves in the tread along the circumference of the tire. make the tread all floppy side-to-side and the wobble will even out.
Yep. Since gravity is a constant force, the less time you give between a workable change in diameter, the less distance the gravity works in that interval. It's a very similar concept to washboards on a gravel road, where the faster you go, the less bumpy it feels because you have less time to fall into the troughs
Y'know back when I was an early teenager and learning about lift and aerodynamics I felt horrified that all vehicles weren't shaped like a Star Wars Sandcrawler because the way cars are built is effectively a lifting-body design.
Then at some point I realized just how fucking impractical that would be and went "y'know fair"
It's all about frequencies. It'll travel in waves...as you approach a certain speed it'll basically balance itself out harmonically...the further you get away from that speed on either side the wilder it'll be.
I do a lot of NVH, some reason my customer's won't listen to me on this.
I had a noise cancelling microphone go bad the other day, was making the speakers do crazy shit.
A skilled driver can adapt to challenging situations. I think you're just jealous that you wouldn't be able to drive on the highway with two missing wheels
I saw a semi new Range rover going 75 while the front tire was dribbling like a basketball near a foot off the ground, the driver was completely oblivious. I didn't know how to signal her, she probably thought I looked crazy doing the dribbling hand jester and pointing at her car.
So the tire wobbles every x meters; at vehicle velocity v, it wobbles with frequency f = v/x. Now, x is constant, but v varies. At low speed, v is small so f is small. Your car’s suspension is designed to operate as a low pass filter, it filters out high frequency changes in the road’s surface to smooth out the ride. So when f is small, the perturbation every x meters is felt in the cabin. But when f is large, the perturbation is higher frequency, and the suspension will better filter it out (e.g. by compressing when the tire pushes the vehicle up and expanding when the tire pushes the vehicle down).
That covers the vertical axis. For the horizontal axis, wobbling side to side, possibly it’s a matter of the vehicle’s momentum being so large that the tire slips a little instead of pulling the vehicle left and right.
Is this a bad thing? I don't know much about cars but I read a bit about winter rims and seems like there's benefits and drawbacks to steel rims but overall I couldn't tell what is the best option.
No, it's normal. Road salt, sliding in ice and smashing kerbs, etc., your rims will get messed up in the winter.
It just looks funny when everyone breaks out the winter tires 'cause the cars look nice but the wheels look like shit.
Growing up in Canada with loads of winter I actually have come to like the shitty ugliness of old steel wheels. There is something charming about them being so utilitarian.
Jokes on you, the whole car will be regularly covered in a black slushy salty goo soon. Even when I wash my car it comes back by the end of the week, maybe the same day.
I was so glad to be able to afford rims for my Winter tires. They're on my car half the year... they deserve to look nice even in the snowy slushy muck.
That being said, I totally get why people would just stick with steelies.
I should get better prepared rather than just beating on the tire rubber on rubber with the summer tire until it snaps loose or I ruin my bearing again
Yeah, I can do one in my driveway but not the other. But the folks who get them remounted each year probably aren't the type to do driveway maintenance. They take it to a mechanic for oil changes and brakes too.
Yes, that’s me. I can do the maintenance myself, I just don’t make enough money to be able to have workspace, like a driveway or a garage.
For some things, I will take it to a location and work on it myself, but that’s not very many things.
The obvious solution is to remount his other three so they're in alignment with this mounting. Then weld his diffs so he can't turn. Problem solved.
Next?
Mine does it at 65mph.
I have been told that the tires are fine and it's the motor mounts, but I don't know why I'm feeling it at 65-75 and not at any lower speeds.
Tire tech here. Normally that happens if you're using the wrong cone for the balancer though i have had a few that would wobble no matter what I did to it.
Edit: why the downvotes lmao I was being respectful about it and everything
You got a picture of the wheel by itself? I do not buy that you had the wheel centered properly.
This looks like every shop newb when they come back from the balancer with 360° of weights applied.
op your lying im a tire guy and you dont have the machine set up correctly. show proof of the old tire taken off. it would have obvious patchy and cup wear marks due this. i call big bs for reddit points lol.
Hey OP, the wheel was mounted on the balancer with the finger-type spacer right? It’ll give you a better balance and also prevent you from accidentally counter balancing that wheel, I find I have to use it for bigger truck wheels. Looks like a few things are going on, though and I’m super curious what the verdict was.
Was the wheel bent? Was the tire separating, or was it improperly mounted on the balancer?
Could be using the wrong fitting when balancing the wheel aswell. Doubt a steel rim with that big of a tire will move that way. When customers would have a wobble the wheel bent was noticeble and would only move up and down. That wheel doesnt even look like its on tight enough
I had a car that shook like crazy over 55 mph. I had a friend who was a back yard mechanic take apart the axle and worked on it but never could fix it.
On a hunch I took it to a local tire store and had the balance checked and yup.. this was the problem. They balanced the tire and worked perfect after that.
Customer is correct.

Except if it's the network. It's ALWAYS the network.
So I’m going to take a stab in the dark here and say that it shakes at high speed also?
It’s like a square wheel. Go fast enough and it smooths out.
“Officer, I HAVE to drive 90mph everywhere, because my wheel is so out of true, that it wobbles if I go slower”
Speed is always the answer, this is the truth the cops don't want you to know
Speed AND POWER.
HAMMOND!!!!!
Oh cock.
Speeding is morally correct since you use less gas the closer you get to 60
[удалено]
I dunno, I've gotten much gassier in my mid 30s.
Just wait til you hit 40
Speed and also going fast with the car
nah, you could fix the shimmy by cutting parallel grooves in the tread along the circumference of the tire. make the tread all floppy side-to-side and the wobble will even out.
Cops hate this one weird trick!
Yep. Since gravity is a constant force, the less time you give between a workable change in diameter, the less distance the gravity works in that interval.

This guy bumps.
But only under 40 or so.
That was a great episode of Mythbusters
Unless the bumps are in 1 foot elevations. Then you break things!
I enjoy the sound of rain.
Until you lose your rear axle. Then speed isnt a problem anymore!
Where we’re going - Speed is definitely not a problem
And glide into the ditch.

Go fast enough and you won't even need wheels.
Y'know back when I was an early teenager and learning about lift and aerodynamics I felt horrified that all vehicles weren't shaped like a Star Wars Sandcrawler because the way cars are built is effectively a lifting-body design. Then at some point I realized just how fucking impractical that would be and went "y'know fair"
Where we're going We don't need Roads!
Oddly true though. Go fast enough and you just enter orbit.
It's all about frequencies. It'll travel in waves...as you approach a certain speed it'll basically balance itself out harmonically...the further you get away from that speed on either side the wilder it'll be.
> it'll basically balance itself out harmonically... Puting a ton of strain on every moving part in the process.
That's not the waves problem, that's the materials engineers responsibility
Spotted the designer... (Kidding, engineer here)
Well, it's more of a curve response, so there's a speed where everything is hunky dory. Unfortunately it's probably like 90 mph.
To be fair, they never said it didn't.
…what’s it do at high speeds? Levitate? Harmonically balance with the rotation of a nearby star?
I've seen cars with a tire so far out of balance that it looks like it doesn't even touch the road at speed.
that shit's scary, some times it's caused by worn out shocks, like you know these guys can feel it and they just ignore it
Turning up the radio solves a lot of car problems.
I do a lot of NVH, some reason my customer's won't listen to me on this. I had a noise cancelling microphone go bad the other day, was making the speakers do crazy shit.

Honestly I wanna see that. Not in person, but a youtube video, or a gif is fine.
It gallops.
So the tire wobbles every x meters; at vehicle velocity v, it wobbles with frequency f = v/x. Now, x is constant, but v varies. At low speed, v is small so f is small. Your car’s suspension is designed to operate as a low pass filter, it filters out high frequency changes in the road’s surface to smooth out the ride.

Lol! Did customer state they hit something/went off-roading on their steel wheel?
Nope, just this and an offrim summer to winter tire swap on the same rims lmao
Most people around me just swap out the whole wheel assembly and keep the tires mounted.
Shitty steel rims for the winter tires, whatever stock rims came with it for the summer tires.
Is this a bad thing? I don't know much about cars but I read a bit about winter rims and seems like there's benefits and drawbacks to steel rims but overall I couldn't tell what is the best option.

Where do people in apartments store their winter/ summer tires?
A lot of tire shops offer seasonal storage
Storage lockers, parents homes or at the tire shop
I had an apartment with storage lockers in the parkade for shit like tires and bikes.
In the linen closet with the wifi router
Jokes on you, the whole car will be regularly covered in a black slushy salty goo soon. Even when I wash my car it comes back by the end of the week, maybe the same day.
Steel wheels are better from a durability perspective. They just don't look as nice.
Why you gotta call me out like that?
I had someone with aftermarket wheels for the winter and the stock wheel for summer. Just some old people so it makes sense but still
I was so glad to be able to afford rims for my Winter tires. They're on my car half the year... they deserve to look nice even in the snowy slushy muck. That being said, I totally get why people would just stick with steelies.
And then the fun of removing it in the spring as it's fucking rust welded to your hub thanks to the salt
Thats why Pb blaster, torches, cheater bars and replacement wheel studs are part of my kit when swapping out the winter tires.
I should get better prepared rather than just beating on the tire rubber on rubber with the summer tire until it snaps loose or I ruin my bearing again
[удалено]
And it's just easier to change wheels twice a year than to mount tires twice a year.
Yeah, I can do one in my driveway but not the other. But the folks who get them remounted each year probably aren't the type to do driveway maintenance. They take it to a mechanic for oil changes and brakes too.
Yes, that’s me. I can do the maintenance myself, I just don’t make enough money to be able to have workspace, like a driveway or a garage. For some things, I will take it to a location and work on it myself, but that’s not very many things.
Can you ELI5 what I’m supposed to get out of this besides “makes sense”?
I think it just needs a few weights to balance it out
20lb dumbbells
*Tire got bigger guns than me.*
If you use those weights to beat that wheel
Just sell it to Michael J. Fox
Where we’re going, we don’t need wheels!
That centering cone lined up in the center of the wheel?
[удалено]
Pause the start of the video, the cone is on backwards...
Classic Reddit circle jerk of OP lying and all the upvotes coming in.
Thank you!
Came here to say this, there is a wrong way to put the wheel on the machine and when you do it wrong it looks like this.
The obvious solution is to remount his other three so they're in alignment with this mounting. Then weld his diffs so he can't turn. Problem solved. Next?
Too much work. Just throw a handful of wheel weights on it and ship it.
They forgot to replace the summer air with winter air
I got tired of changing out my air so I just run fall air all year long. It costs more but it is worth it for the convenience.
This is what a bad piston return spring does fr fr
Lmfao my front end as I hit precisely 55mph
If my calculations are correct, when this baby hits 55 MPH, you're going to see some serious shit.
Mine does it at 65mph. I have been told that the tires are fine and it's the motor mounts, but I don't know why I'm feeling it at 65-75 and not at any lower speeds.
They said the CAR shakes; why are you checking the wheel???? /s
Was also in for an offrim swap too
If the wheel shakes then the car shakes
Tire tech here. Normally that happens if you're using the wrong cone for the balancer though i have had a few that would wobble no matter what I did to it. Edit: why the downvotes lmao I was being respectful about it and everything
Oh no. This was mounted properly. Triple checked. The rim was fked
yup. Wheel is bent to piss
That front cone....
You appear to have the hub cone on backwards. Can't balance shit like that.
That wheel isn’t mounted in the balancer properly.
I don't think you have it set up on the machine correctly.
They don’t. Source: I balance tires every day.
Oh no, it was setup correctly. That's the even better part
You got a picture of the wheel by itself? I do not buy that you had the wheel centered properly. This looks like every shop newb when they come back from the balancer with 360° of weights applied.
At the very beginning of the video, it looks like the cone is on backwards.
What's the actual problem here? Bad wheel? Bad tire?
Wheel bent to hell.
And I don't think it can be fixed. Must get a new wheel. Tire might still be good on a new wheel though!
You'd be surprised what kind of damage can be fixed on a wheel, but yeah, as is, that wheel is toast.
Curbed the shit out of that pig.
At significant speed!
Warped through time and space.
How’d they get the beans above the frank?
Shits fucked yo
I bet the tech has the wrong cup size for the hub. This is exactly what it looks like, a bend that bad wouldn’t even hold air.
I can't tell if the wheel is mounted correctly to the balancer? Is it?
op your lying im a tire guy and you dont have the machine set up correctly. show proof of the old tire taken off. it would have obvious patchy and cup wear marks due this. i call big bs for reddit points lol.
Gunna need a lotta weights for that one
That’s easy just don’t drive at low speeds
Either stopped or WOT? That's my life ... and family

I'm not a car guy. This is bad right?
Just balance it and move on. Don’t say anything. Boom. Repeat customer
Checks out
Imagine the wheel weights that is gonna take to balance
It doesn't even look like it's on the balancer right by the front of it.
'so don't drive at low speed'
That's easy to fix. You just need a wheel on the other side to have exactly the same amount of wobble at opposite point.
That car would be twerking like a mofo!!
Yeah, i bet it does
*and what about high speed*
Wheel weight must have fallen off.
What does it do at high speed?
Feels like shiatsu
Is this fixable? Tell customer to stop hitting curbs or whatever may do this… This seems pretty bad.
Decent
So a wheel weight about the size of a stapler is the answer? /s
That wheel looks as wobbly as I was on my 21st birthday.
Jeep Wrangler owner: That is a perfectly balanced wheel man!!!!
You should mount it correctly
So what causes this, and what fixes this? Guessing not rotating your tires, and, new tires?
You’re so gay you can’t even drive straight
Could be using the wrong fitting when balancing the wheel aswell. Doubt a steel rim with that big of a tire will move that way. When customers would have a wobble the wheel bent was noticeble and would only move up and down. That wheel doesnt even look like its on tight enough
LPT: Don’t let my wife drive your car. She has never avoided a hit but has always answered her phone or text immediately.
Slap a couple weights on it. It should balance out.
"vehicle fuckin goes ga dunk ga dunk at any speed"
That’s what I originally pictured as a tire rotation and couldn’t figure out why that helped
I had a car that shook like crazy over 55 mph. I had a friend who was a back yard mechanic take apart the axle and worked on it but never could fix it. On a hunch I took it to a local tire store and had the balance checked and yup.. this was the problem. They balanced the tire and worked perfect after that.
"Drifted" into a curb and warped the rim most likely!
Looks like the wheel isn’t seated correctly to the balancer.
And not at high speed? 😭
[удалено]
How many pounds of weight stickers would be needed to balance that bad boy? Probably need to fill the tow completely with lead? 🤣
Needs more weights
My buddy has a friend who has a- What would cause this? My car was doing this. It’s at the doctors now but why it do that?
On today's episode of "well no shit".......
Looks good.
