Need help changing out lower control arm bushings?

First off, I DON'T want hate comments on how I'm running ProComp lower control arms with bushings at both ends. Yes I know it doesn't flex as well as joints and has the risk of tearing off the control arm mounts. When we bought the Jeep this is the lift it had on it, and I don't have the cash to spend on 2 pairs of new arms.

Anyways, I need help. I was wondering what do I have to do in order to change out the bushings? Do I need to lift the Jeep and rest the frame on jackstands? Do I need to take off the tires and rest the axle on stands? Can I just go at it without putting anything on jackstands but do one arm at a time? What is the prep work? Thanks,

- Josh


Here is a picture of the arm



and the f'd up bushings

You are going to get all kinds of responses to "the best way". I would leave it on the ground and I work with one control arm at a time. Two bottle jacks with one under the spring bucket works for me. If, your junk isn't lining back up when you you reinstall the CA then you use the bottle jacks to apply pressure where you need it.

This works for me and all my work is done on an off camber, unlevel drive way.

you can remove the control arms without jacking up the jeep. I use the basic wrenches, and if needed a prybar to move the axle around. I only remove one at a time tho.

I know how to change stock bushings, but Im not sure about those. I might be changing out some this week, since my rear upper arm bushings are shot, and they are new adjustable arms. All of the bushings in the stock arms are still good and its a 97...

Im curious as to what your saying about ripping mounts off with bushings instead of something else like a jonny joint or flex joint. Is that a common problem? Im wondering if this might be a cause of why my bushings are toast after 4 months..

Got one side fixed. I had to cut the LCA bolt off because for some reason 4WheelParts installed it so if you try to take it out it hits the brake drum. So instead of having to take off the drum I just cut the head of the bolt off and slid it out the other side. I put the frame on stands just to take some weight off of things. Well here's some pics of like the old bushings, the old crush sleeve, and installed.

Because a flex joint at one end of the arm lets the arm ends swivel independantly when one side of the axle droops and the other end stuff. (Factory arms are just flexible and they whole arm twists.) A solid fixed arm with only urethane bushings at both ends put huge stresses on the bushings and just destroys them quickly, and severe flexing can actually bend or tear off the flimsy near-sheet metal mounts from the frame since urethane is so stiff. If I had fixed arms I'd rather have rubber bushings that flex more.

Ordered a direct replacement by ProComp from my local 4WheelParts. Cost about $90 for all the lower control arms.
