I have a 1985 300ZX Turbo that makes a large clunk sound from right rear wheel area when I hit the slightest bump. Everything seems to be intact and working properly in the suspension. I have the electronic adjustable shocks and have been told they cost $1600/pair. Are these shocks repairable? Have I overlooked another possible cause of noise?
Thank you for your time.

 

Yea your shocks is done. You can replace it with Tokico Illumina

 

Replace your shocks. Might also want to check your bushings to polyurethane.
