Installation Notes and Tips

Install TC8387 on the front right lower suspension position only. Verify the mounting hole diameter, bushing dimensions, and ball joint orientation before installation, and torque all fasteners to the vehicle manufacturer’s specifications. A professional alignment is recommended after suspension component replacement on Mercedes-Benz GLC300 and GLC350e models.

Quality Assurance

Delphi uses OE-based engineering and testing for aftermarket steering and suspension parts, including temperature cycling below -40 degrees C and above 120 degrees C, plus extended salt-spray exposure. This helps validate material durability and dimensional consistency for the listed fitments.
