• Excessive play in the front right lower control arm

Installation Notes

Verify vehicle year and front right lower position before installation. Because the ball joint is press-in and the arm is non-adjustable, proper removal and installation tools are important for a correct service. After replacement, a professional wheel alignment is recommended to confirm suspension angles and steering response.
