Review on 💯 Dorman 905-499 Front Upper Shock Insulator: Enhance Ride Quality and Comfort Effortlessly by Daniel Reeder

Replacing the lower and upper shock absorber bushings reduced the rattle problem when hitting small bumps on a rough road, but did not eliminate it. I really didn't need to change the top bushing because the bottom bushing would shrink over time. But even with interchanging both, the problem is that a steel bushing with a nylon outer bushing will slip onto the strut, seat in the lower bushings, fit into the upper bushing, and be too long. Tightening the nut on the strut to compress the rubber bushings is limited by the steel bushing abutting the lower and upper washers holding the rubber bushings, so you can't compress the rubber bushings enough to eliminate the chatter. I'm going to grind down the old steel bushing about .050" and install it to make sure the rattle is eliminated.
