Dumb Question, but I'll ask just to make sure.

Is it safe to jack up the back of car with the floor jack on the rear diff?

My floor jack is more then big enough for the weight but I don't want to damage my rear-end. The front is already up (again), so I want to get the rear up all at once to minimize the chance of the car being off balance and sliding while its going up.

Yes it is. I jack the back of mine up that way and put the jackstands just inside the leaf springs.

 

[evilfitz]

Thanks, I figured it probably was. I have to replace my leaf springs and etc. So I'll have to put my stands right behind my sub-frame connectors plus one more somewhere further back if I find a good spot out of my way just to be on the safe side.

It is safe to lift it that way but do not work on it like that, and when you put the stands under the axle do so without getting your body underneath anything.

If you are taking the springs out, then there is nothing connecting the rear axle to the frame, so lift it that way but put the jack stands on the frame or your subframe connectors (thats what I did).

Ideal jack stand locations for rear spring job:

Jack the car up by the rear, place 2 stands under the rear subframe just north of the spring bolt in area, then lower the rear to 0 load (no weight on the springs and not pushing up on the springs either) and place stands under it. This will keep the rear in the right spot while you man handle the springs out.

I put mine up on four jackstands. Two in front and two in back. All on the frames.

Be sure to use chock blocks on the front wheels.

be REAL careful if you're using a floor jack to lift the rear up when the front is already on jackstands. I say this because a floor jack doesnt lift the rear straight up, it moves it slighty forward or backward as it comes up. Nothing in the world is creepier than seeing a car rock forward tilting the jackstands. dont ask me how i know.

 

[D.Hearne]

That's why you use a floor jack that's got wheels on it Or at least that's what we rednecks use to prevent the jackstands from tilting.

on beat up old concrete sometimes those little 2 inch steel wheels have trouble rolling very far.

I made some front wheel blocks out of some spare 2x4 and 2x6. Put the front wheels in the blocks and then jack up the back of the car...it won't go anywhere. I have already bet my life on it....more than once.

Let me know if you want a picture of my wheel blocks.

That's why we pave the front yard with new concrete!!!
