Process for using 4 jack stands

Hi guys,

Is there a recommended method for jacking an entire vehicle off the ground? In other words, should I first jack the vehicle from the front and place two jack stands in the front, and then proceed to jack the back side and then place two stands under the back? Or should I do the back first and then the front? Or should I start by jacking it from then left side and then move to the front? I'm thinking about 4-wheel tire rotations here, when the entire vehicle needs to be lifted since the wheels need to be crossed.

tx!

I say lift the front first by the pumpkin (differential). Then lift the rear by the pumpkin.

You don't have to do it that way, but be careful as using 4 jack stands can be unsafe if the vehicle isn't properly supported.

i do fronts first, the rear wheels are held by the emergency brake and the transmission while the front is lifted, then raise the backs up.

The jeep can roll if the rears are done first...just my .02 cents

Yeah, this is a big concern of mine ... but it's the only way to rotate the tires. Are there any good tricks to testing the stability of the vehicle once it's lifted on all 4? It's a whole lot of weight should it come tumbling down. Almost makes me want to get a same-sized 5th wheel just for the purpose of not having to jack the entire thing off all fours

Yea, I always rotate mine with the spare, but I don't drive on the spare, I just put it on and 2-3 lugs and rotate all of them until it goes back to the front. That way only 1 wheel is lifted at a time. But that's also because I don't have 4 stands, only 2.

And just make sure you can lightly push the Jeep and make sure it's stabilized.

if you put the jack stands as far outward as possible in the axle tubes, and only get the tires a couple of inches up you are good, its not going anywhere. i usually leave my floor jack under the differential after its set on the stands, snugged up but not lifting as a piece of mind kinda thing.

jeeps are light compared to the ratings of jack stands, and as long as they are not cheapies their bases are wide enough to keep the jeep from rocking...even if you lean on it...

I have had people go rabid frothing at the mouth telling me never to lift a vehicle by the pumpkin. Something about putting too much stress on where the axle tubes attach to the pumpkin. Since the weight of the vehicle is usually pushing down on the spring mounts near the wheels, there is little stress on where the tubes join the pumpkin. When the pumpkin is used as a lift point, all the weight on the spring mounts is cranking down on that connection point like a giant lever. Anyone here have opinions for or against that? I'm not saying one way is right/wrong. Just wondering what the common consensus is.

I've been doing it forever now, my grandfather did it too. I've never heard of anything bad by it.

But I'm all ears.

I just rotated tires yesterday without using the spare.

-Put the front on jack stands and remove tires. (i don't use the pumpkin, just place one jack stand at a time)
-Jack up one rear and tire and swap while on the jack (if you want to be uber safe put the other front tire under the LCA)
-Jack up other rear tire and swap.
-Install rear tires on front.
-Remove jack stands.
-Done.
