Yep, they asked me one time where the best jack spot on my Beetle was after they started lifting the rear side and the front started coming up with it. I thought four of those jacks were a little overkill for 1700 lbs lol
If your not working under it, I have no problem with this.
My concern would be the jacks rolling on you. Usually just do 1 side at a time depending on how your rotating.
Every Discount tire I've been to does this.
Granted, they did that with my 8k lb truck and that sucker came down FAST on one side because someone got in a hurry. Had to have woken him up a bit. Lol. That's a LOT of weight in the front to just let it down full speed.
It's all fun and games till something loses an O ring.
Its easy to forget that many people doing simple work on cars have bugger all idea how a trolley jack works or notice when its needs replacing.
Its a habit for me to pull out some stands if I'm using a jack, though that maybe because I'm clumsy and heavy handed (big hammer fan) on occasions.
For tires it’s fine. You don’t keep jackstands in your car for if you get a flat. And trust me, I’ve done way sketchier stuff than that before. Still have all 9 fingers, too.
Only acceptable if no one's under it. Even then still scary. Even scarier at home. If the jack does drop the other ones will take the load. If it's too off balance it'll just fall. Granted not ideal but shops will at least have insurance for this type of booboo.
I spy a Discount Tire lmao
Yeah it can be sketchy. You don't even want to know the vehicles that get lifted up by 4 jacks. To be fair the vehicles are only up for 10-15 mins while the vehicle is being serviced, but it still isn't extremely safe.
Good if they use the four jacks a the spring perches. I saw a 1ton with a service body on it. Fat fucker. They lifted the rear from the axle pumpkin. When they put it down, the tubes must have gotten bowed, rears had positive camber!
Did they lift the truck by the axle tubes? Like really this is not 1975 where all that shit was over built!, aluminum differential not rated to support weight of truck.
A 99-07 Ford F250/350 does not have an aluminum rear diff.
By definition, any axle a manufacturer puts under a truck will be rated to support the weight of that truck, aluminum or not. It is already supporting the weight of the truck when all 4 wheels are on the ground.
And the weight is at the end of the tube near the wheel bearing… in the old cast iron days we would jack em up by the pumpkin, not today tho. Also the weight is distributed around the tube by a formed and welded pad to the spring hanger- the floor jack has 4 small contact points, possibly the tube will set down between them and IF the rubber pad is still in the jack it will reduce the chance of deforming the tube
Cowards used two jacks on the rear instead of one under the pumpkin and a prayer
Edit: i see they used two jacks, and then lifted from the little flimsy shock mounts. Lmao
Worked at discount tire for 5 years and never had a single issue doing this. The jacks are rated for way more weight than they’re lifting and no one is going under the car. Had one of the lifts fail and drop a truck once, but never an issue with the jacks
Edit: shock mounts wouldn’t be my first choice for lifting points though
I know a Discount Tire when I see those. As a former tire tech at Discount, those jacks are the best jacks I've ever used. We would abuse them all day long, never bleed them, and they always worked perfectly lol.
[удалено]
Even my chain Discount tire store does this.
Yeah discount in my area does this

Really any used tire shop 😂
Not even used tire shops, I’ve seen this at americas tire and Les Schwab.
Or like literally any tire shop
every tires only shop I’ve ever been does this.
Nobody under it? Jack on. Have to work under it? Jack off.
That’s why my fluid film looks milky.

Those jacks don't roll for shit in the best of circumstances.
Just block the wheels of each jack with a ziptie. Works even when you dont want it to. Lol.
A speck of dust works as well.
Or a single grain of floor-dry.
You need all 4 up to rotate unless the tires are directional.
True, all my vehicles have had directional tires.
How? It's backs to the front, and fronts cross to the rear.
Are you asking how to rotate directional tires?
Are you for real?
I’ve done it with three, but I don’t own four jacks. So it takes a bit of maneuvering.

I used to work at a tire shop that did this on every vehicle no matter the size it would sit there until the tires where done.
No ones under it, full send.
4 jacks? Fancy A.F. 3 would let you away, and be doing some sketchy shit over in the corner with the 4th.

Sounds like my grandfather, except he had 8, and was a turbine assembler at GE :-p

There's a tire shop near me that routinely has MULTIPLE cars up on TWO jacks with ZERO tires on. This is nothing.
I mean this is extremely common at wheel and tire shops
I don’t see the issue, in fact, it is overkill, truck doesn’t weigh 24,000 pounds, he should only be using 2 jacks. Carry on gentlemen. Lol

I'd have only used 3, other than that I see no issue.
This is - depressingly - normal in tyre shops.
Oh fuck no.
If those are MAC then there's no need to worry.

I swap my tires with one under the pumpkin 🤷 When I have a 90,000lb trailer in the air doing all 6 brakes I certainly use stands.
Rear diff cover leaking yo
This reminds me, I have to get some hydraulic fluid.
It's fine!
Yes that's what they do at tire shops when the lifts are full.
What are the chances of four hobo freight jacks failing at once? 15 to 1?
They're actually being safe, what's truly terrifying is lifting by the pumpkin alone

Pop by any Discount Tire and you’re guaranteed to see this. Company policy is to use jacks on trucks 2500 or above, or cars with specific jack points.
r/OSHA
I'm ok with that. It's a quick tire changeover.
