Replaced the rear upper control arms and lower control arm bushings this weekend.Got the lower arm bushings on eBay and the bushings turned out to be Hamburg tech brand which has poor reviews for quality..Since there are few other choices available I decided to keep them and install.Will see how they hold up.The bushings looked OK and the only thing I did was add more grease to each one.The only problem I have is the solid rubber bushings I received are the wrong diameter so they will go back.The original rubber bushings looked OK so I left them in the arms.The original bushings also are slotted as compared to the replacement ones which are solid rubber.So even if they had been the right diameter I wasn't sure I would have used them since they aren't the same design.End result is a tight suspension and saved $$ by not replacing the complete arms.
