Installation Notes and Tips

This bushing uses a press-fit design, so proper suspension service tools are recommended for removal and installation. Confirm the exact rear position on your Mercedes-Benz application before ordering, since this part is listed for rear, rear upper inner, and rear upper outer locations depending on model and year. Verify dimensions and OE reference before installation to ensure correct fitment.

Quality Assurance

Delphi applies OE-level dimensional and material analysis to support aftermarket fitment accuracy. This bushing is tested for temperature extremes below -40 degrees C and above 120 degrees C, and it is exposed to 720 hours of salt spray during validation. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
