eg8........I've got front and rear upper strut bars. The problem is when I put the rear (or trunk bar) in every bump I hit no matter how small squeaks like a bad mattress. When I took it off this weekend it made no such noise. It's only on the passenger side rear. I thought it was the strut assembly before i took the bar off, now i'm thinking maybe stressed mounting points or something. Any ideas? O yea it's on stock shocks and springs......
