Rear spring plate replacement

I need some help, I have to replace my rear spring plate and I'm worried this is going to be like opening one of those cans with the spring worm in it. How do I get it off in a safe way?

Looks like your right about there. You have the jeep up on the frame, now use the floor jack under the Diff to take some weight off the springs and unbolt.

I'm not really liking the block of wood on the jackstand but other than that you are ready to go. The axle is over the spring so nothing will fall except the bottom plate when you unbolt.

Best practice calls for not reusing ubolts.

The other side is still sitting on the ground, does that matter?

I also worry about the axle rising up to the bump stop and knocking it off the jacks

you need to have both left and right side wheels off the ground, with jack stands supporting the frame.

Thanks, that crossed my mind but I really was not wanting more wood blocks holding it up.

That's it. Raise the rear end and sit the frame on jack stands making sure the wheels aren't resting on the ground. If the rear end is just hanging there without any ground contact then just unbolt the ubolts to remove the spring plate. The axle with just sit there on the springs, no worries.

One thing I do when I don't have enough wide pieces of wood to stack UNDERNEATH the jack stands... I raise the rear end up at the diff and set the jack stands under the frame rails. I then remove the tires so when I lower the axle back down to just hang the jeep isn't as high in the air. You might not be able to get an impact under there but if you just but you can just go higher unless your using a breaker bar.

what he said ^^^

Just be careful and have the tires under the frame for extra safety

best = taller stands
next best is a platform of solid wood under the stands.

If only one side is jacked and the vehicle is slanted it's easy to jostle it off the support.

Harbor freight has 6 ton jack stands that will go really high. The work well for lifted jeeps and are inexpensive. Get some decent jack stands to support the frame and the rest is easy.

When I did my lift, I gathered 4 jack stands. 1 for each frame rail and 1 for each side of the axle. I jacked up the rear end, pulled the tires, then lowered it on to the frame rail stands. Once I had the frame supported, I slipped one under each side of the axle to support the axle. Now the axle can't come down too far and the frame is supported. From there the only thing that can move is the spring.

I removed the shocks first, so I didn't over extend them, then dropped the springs. Since you're just doing the plates, you can add 2 more jack stands - front and rear of the spring plates - to keep the springs from dropping too far.

Safety first, second and third.

Those plates look pretty good, looks like they are skid plates with recessed nuts. I'd clean them up and repaint unless they are rusted out. Here is a link for u bolts, though any off-road shop ahs them.
