What is Up with My Spring Plate Bushing

Yes, this is an old thread. I never identified the exact source of the noise, just the general area. I did fab a piezo microphone to sound amplifier to verify the general vicinity of the noise, but not the specific suspension components making the noise.

I had the car on a dead level surface with the rear end high enough for the rear tires to be off the ground. The left rear tire was two or three degrees greater positive camber (bottom in) than the left side, so I replaced the banana arm with a known good arm. I was working under the assumption that in the accident that caused the right rear quarter to be replaced the banana arm was slightly bent. Once the new arm was installed, the degrees of camber, without ever moving the car were the same on both sides.

It appears to have resolved the issue. The spring plate cover can be installed without an issue and a new bushing doesn't look compressed immediately. I declared victory.

911's are great cars, but any odd creak, clunk, whine or tap can be maddening for me. I am better at ignoring the minor ones now. I still have the car and still continue to work through my project list. I'm 64 and still really enjoy the ownership experience. I have considered going to something newer as I get older, but am afraid I will regret it. Can't wait for summer!

Thank you for including the solution to the problem!
