Installation Notes and Tips

Verify the vehicle position before installation: front left lower. Compare the original arm, ball joint mounting style, and stud type to confirm match before removal. Inspect adjacent suspension parts, alignment angles, and fasteners during service. Because this assembly is non-adjustable, a professional wheel alignment is recommended after installation on Chevrolet Colorado, GMC Canyon, and Isuzu front suspension applications.
