Differential Housing as a Jack Point?

Do you use the differential housing as a jacking point for your floor jack? I've heard that you shouldn't and that you can lift your vehicle from there. Has anyone here ever had a problem after doing so?

My rear, yes, I jack it up all the time. In the front I jack from the frame since the diff. is off center. I'd bet it would be ok to use the front diff. too.

Just make sure you have some wood between the metal jack and the diff. If you scrape or mangle the diff. cover, it won't seal right and you could get a leak.

Most of the writeups I've seen (not sure about the Haynes manual) specify using the diff. as a jack point.

Just keep in mind if the axle can't handle a floor jack on level ground how good can it possibly be on the trail? I have used the diff housing hundreds of times on a wide range of vehicles without a single issue. As HolidayJeep mentioned just take precautions if you don't want to scratch that axle, but let be real it’s a jeep and they are meant to go off road so they will be scratched eventually so why worry.

i've used the front diff when fixing sway bar link issues to get the jeep to raise off center on purpose. works fine.... just be careful, use jackstands once you get your jeep in the air, otherwise its pretty unstable.

Definitely use jack stands either way, esp. in the front. I tried using the front diff. as a jack point one time and really didn't seem very safe.

Can you jack it up from the axel housing? I thought that was the jacking point for changing tires.....

I usually jack it up under the control arm mounts, then insert a jack stand if I'm going to be under the TJ for a while.

I always use the diffs to jack up the vehicle.. ever since i went in for a tire rotation and the saw they did it. never had a problem... I jsut make sure the tray is not on the cover..

I never have aproblem getting the forn on jack stands when jacjing from the differential either.. jsut set it down easy.

It can ben done despite being way off center, I have done it a few times. Just make sure you get the jackstands under there asap.

if your cover gets bent from jacking the jeep up then your screwed on your first wheeling trip









the axle tubes, diffs will both be safe to use to lift the jeep, they hold alot of weight as is you will be fine

I use to jack it from the passenger side axle tube, as close as possible to the diff. housing and than 6 tons stand under her asap. That's for the front. For the rear either the diff housing or the gas tank skid (if i don't have to lift it to much)
