Good reason to replace rear control arm bushings
These didn't "look" bad when they were mounted on the car, but this is what I found when I went to replace them. Glad I did. The metal wasn't damaged. From a 1984.
Just another reason for me to install my bushing set that has been on the shelf for 6 years.

I have a '92 with an automatic. Each time I put it in gear or put a little pressure on the rear end there is a click from the left rear. Once I'm rolling down the road there is no noise at all, just one click when pressure is first applied to the rear end. I've had all the u-joints checked out and everything looks fine. One mechanic thinks I need to replace the bushings in the rear. Did you have those symtoms on your car?

I'm replacing the rear bushing on my 87 as I type this, reason is to have the rear end lined up. Can't really do the job with bad bushings strut bushings were shot. Also changed out the shocks looking forward to seeing the difference. You should check your swaybar end link bushings also they go bad before the dogbone & strut bars do.

big difference, use alot of marine grease, really painful job though....but worth it, mostly labor, the bushings don't cost much....mark the camber position first with white out....

Trying to bring the car back to life... It's up on Jack stands so I figured I might as well. I did the sway bar bushings (there's a set of 22 MM for sale on here someplace for B/O, I read the dial gauge wrong) ... from the responses it looks like I might as well do the differential support bar (bat wing?), while I'm at it. Not even looking forward to doing the front.
OhBTW... those end link sway bar bushings were a PITA.... like Slickfx3 said... lots of grease. I found that boiling them in water for a few minutes softened them up just enough to make it "slightly easier" to press into the hole.

I will let you know what I eventually find out. So far 4 shops, including two corvette shops, have looked at it and can't figure it out. I'll show them 92ragtop's idea and see if that is it. Right now it does not seem to be getting worse and everyone has told me that whatever it is it does not seem to be a safety issue. I probably will not spend much money trying to figure it out unless it gets worse. I have no vibrations or noise at all, just the click, but I hate having something wrong with the car after I have spent so much money on the new engine.

Great help! I did the search and found a thread entitled "Its the washers" which was started back in 2007. That explained everything about this problem. I took the info to Loud Pedal Motorsports in Tempe, AZ, and they have ordered the parts and we are scheduling the fix (I have a hard time replacing light bulbs). Thanks for your help.

That is not the location of the teflon washers
They fit on the spline inside between the bearing & yoke
They have nothing to do with the washer you show
Here you can see where they go

I have a '96 and the left rear bushing is rotten. Had suspected this for a while, I do not enjoy the squishy hard to predict feel of the rear end at the limit.. Will replace all with poly as soon as I drum up the courage to take my car apart
