Is the rear diff still the best place to jack up the back end?

For some reason I have never been a fan of jacking the rear of the car from the differential but I have never had any adverse effects either.

Just curious if a better spot prevails. I would guess if you jack the car up and quickly place jack stands it's not as bad.

Nope, that's the best place. Why aren't you a fan of doing that??

Yea. It's a good spot to use. Had to jack my from the diff the other day to raise it high enough for the loft arms to clear the underbody.

It's what the factory recommends:

I would rather use the lift points in front of the rear wheels rather than the differential...Gary

Yep, that's why it's better to do the lifting from the diff and then put the stands under the those - carefully!

Thanks for the info guys! My BMW had rubber pads for the jack points and it was awesome given that I had a pair of "flat top" jack stands. I also got lucky and have a squishy (technical term) pad on my jack so it helps the metal on metal contact quiet a bit. My Lexus had the same setup like the G with the "slotted" jack point which is perfect for the trunk jack but not so much the hydraulic ones. I try and get my stands on someone frame/unibody related if I can. If not I just leave the jack up and carefully work around things :0

I've never been a fan of jacking up by the differential. That part was never meant to support that sort of weight like that. I'm sure it's "fine" but I'd rather not use it.

It's fine if you're not a fan and would rather not use it as intended, but make no mistake, it most definitely was designed and engineered specifically to be "meant to support that sort of weight like that". You have the factory's word on it. They endorsed it so much they even put it in writing.

Use the "Hockey puck" method by cutting a slot into a hockey puck and lifting with a standard flat top jack.

+1, if it's good enough for the factory, it's good enough for me.

That's fine, but given the issues sometimes experienced by others with rear diff bushings failing, i'll stick to using other jack points rather than the pumpkin.

(I do not have any data to show jacking from the pumpkin correlates to failed bushings and I'm not claiming it's the cause)
