What It Helps Address

• Front-end clunking from worn control arm bushings or ball joint wear
• Loose or inconsistent steering feel
• Uneven tire wear caused by suspension geometry issues
• Excessive play in the front left lower suspension corner
• Alignment instability after component wear

Installation Notes and Tips

Install on the specified front left lower position only. Verify vehicle year, make, model, and suspension configuration before ordering, since fitment varies by application. After installation, perform a professional wheel alignment to confirm suspension angles and steering tracking. The assembly is pre-greased and does not include a grease fitting.

Quality Assurance

Delphi subjects its steering and suspension components to extreme temperature and salt-spray testing, along with dimensional and material analysis, to support OE-level fit and durability expectations. The TC6663 is built as a standard replacement part for the listed applications.
