What This Part Helps Address

• Excessive front-end looseness or wandering
• Clunking or knocking from worn suspension bushings
• Uneven tire wear caused by worn control arm mounting points
• Steering response issues related to front suspension wear
• Restoration of proper front left lower suspension geometry

Installation Notes and Tips

Verify vehicle fitment by year, model, and front left lower position before installation. Because the ball joint is not included, inspect the existing joint and related hardware during service and replace any worn components as needed. After installation, a professional wheel alignment is recommended to confirm suspension geometry and steering wheel position.

Quality Assurance

Delphi applies OE-focused engineering to its aftermarket steering and suspension portfolio. This control arm is evaluated for dimensional accuracy and material compatibility, and Delphi subjects parts to temperature cycling below -40 degrees C and above 120 degrees C, along with extended salt-spray exposure for corrosion resistance validation.
