SummaryComplaint Thumping noise on rear axle shock absorber on rough road. Cause Until now the rear axle shock absorber support bushing was only available together with the rear axle shock absorber as a replacement part. In future, the rear axle shock absorber support bushing will be available individually as a replacement part to avoid any unnecessary shock absorber noise. Remedy For noise problems on the rear axle shock absorbers, please always make a noise diagnosis, for example using Chassis Ear to localize any sources of noise on shock absorbers or support bushings. If the noise originates from the upper part of the shock absorbers, it is enough to replace the support bushings. Otherwise the complete shock absorber including support bushing have to be replaced. The modified support bushings must be replaced in pairs the first time so that any mixed installation of old and new is reliably ruled out.
