Installation Notes

Install on the front right lower position only for the listed Mercedes-Benz B200 applications. Verify mounting hole diameter, ball joint thread diameter, and suspension geometry before installation. Because the ball joint is already installed, replacement focuses on removing the worn assembly and transferring the suspension connection points to the new unit.

After installation, perform a professional wheel alignment to confirm proper camber and toe settings. Check all fasteners and suspension clearances according to factory service procedures.
