PostSubject: Rear suspension rebuild   Fri May 12, 2017 6:15 am

I'm currently working on rebuilding the front suspension and am starting to think about doing the rear as well. Can someone help me with a list of components that would be replaced with a rear suspension rebuild? I have not found a post about doing the entire rear, just posts about individual components.

Also, is there anything particulary difficult when working on the rear suspension?

Thanks.

The only issue is getting a tool in place for the upper axle to arm bushings. If you are going to remove the axle from under the car, it is not an issue.

I actually had an issue with my '89 Custom Cruiser where the car would shift just a little to the left under acceleration, and it was the upper control arm bushings in the back that were weak. It never wore tires or anything, but you could feel the car shift sideways just a bit.

That 307 will do it everytime!

Pretty easy. Upper arms, lower arms, axle bushings (as said before - removing the axle makes this easier). You can buy boxed lower arms with sway bar mounting points to add a rear swaybar down the line, too.

If you're in there, consider doing rear gears maybe if you want to wake the car up.

I had the same problem with my 94 DeVille except in the front. The front sub-frame bushings were shot. It was bad in the FWD Caddy as it would try and steer me into the oncoming lane. I really had to pay attention.

Thanks everyone for the tips.

I would invest in the stainless U-bolt to secure the top of the rear shock. User Navylifer sells them on issf. If you're doing the work on a lift and have fairly thin arms it's not a huge issue, but if you're doing it at home, you'll want these.

replace the coil spring isolators.

I have the tool to pull the axle bushings. I think I left it in BC though. I could probably mail it to you if you want to use it, but it won't be till July at least. Maybe you can rent it locally too.

""replace the coil spring isolators.""

Use poly material rings. The stock rubber ones only last a few thousand miles.
