These work perfectly for getting rid of the annoying clunking sound. Really tightens up the back end and improves rear shock absorption. Adds a little more drive line noise than was noticed before, but not too bad. The shop I used put the car on a lift, then put a support stand under the member, removed the stays from each side, then took a reciprocating saw to the old bushings to remove them. The new ones slipped right in. Easy fix in shop, took mechanic 30 minutes total.
