Installation Notes and Tips

Verify rear lower fitment before installation and confirm the vehicle application against the part number GS501166. Inspect adjacent suspension components, mounting hardware, and alignment settings during replacement. Because this is a non-adjustable control arm, proper installation and a post-repair alignment check help ensure the suspension returns to factory geometry.
