I just took my 2005 in for the second time after hearing and feeling the right rear "bottom out". The first time, the garage put it on the lift figuring it needed shocks. It didn't. They road tested and couldn't hear/feel any thing, so the next day "we" road tested it over bumps and the problem went away. That was 2 weeks ago.

This time they put it on a different lift so that the wheels wouldn't hang. They found that the bushings nee to be replaced...THE CATCH IS...Chevrolet doesn't sell the bushings alone...THEY ONLY SELL IT as the complete "REAR AXIL BEAM". This assembly costs $475.

Any suggestions?
