Help W/ Daizen Control Arm Bushings

[Soaring]

Hey, has anyone else installed the Daizen polyeurethane control arm bushings? I had a local shop install the upper and lower, front and rear. At the same time I did Eibach ProKit Springs and KYB shocks.

When I got the car back, the rear suspension was clunking. Has anyone else had this problem? I took out the strut/spring units and checked them out. They were fine. I don't know what else to look for. Any hints/ideas?

Thanks!

When does the rear clunk?
