Common Repair Uses

• Replacing a worn rear control arm bushing that causes looseness in the suspension
• Addressing clunks, squeaks, or shifting from the rear lower suspension area
• Restoring steering and chassis response on Mercedes-Benz rear suspension systems
• Correcting uneven tire wear linked to deteriorated rear suspension bushings
• Renewing the rear lower forward outer or rear right lower bushing location during suspension repair

Installation Notes and Tips

Press-fit installation is required, so proper suspension tools and a bushing press are recommended. Inspect the control arm, mounting surfaces, and adjacent bushings before installation, and verify the rear lower forward outer or rear right lower position against the vehicle application before service. Because mounting hardware is not included, reuse or replace related fasteners only as specified by the vehicle repair procedure.

Quality Assurance

Delphi tests this OE-style replacement under extreme temperature and corrosion conditions, including exposure below -40 degrees C, above 120 degrees C, and extended salt spray testing. The brand also uses dimensional and material analysis to support OE-level fit and compatibility for the aftermarket application.
