Detailed Description

Delphi TC8518 is engineered as a suspension control arm and ball joint assembly for vehicles that use a front right lower forward layout. Delphi applies OE-level dimensional and material analysis to support proper part-to-part compatibility, and the assembly is tested across extreme temperature and salt-spray exposure conditions to verify durability in demanding service environments. This part cross-references OE numbers 68329 916AA and 50535567 for the same application.

With an aluminum arm, rubber bushings, and a pre-greased ball joint, this assembly is built for stable suspension movement and consistent steering response. It is a direct-fit style replacement for Chrysler, Dodge, and Jeep applications that use this configuration, including select Chrysler 300, Dodge Charger, and Jeep Grand Cherokee models.

What This Part Helps Address

• Front-end clunking from worn control arm bushings
• Loose or inconsistent steering feel from ball joint wear
• Uneven tire wear caused by suspension geometry issues
• Excessive play in the front right lower suspension link
• Noise over bumps from deteriorated rubber components

Installation Notes and Tips

Verify the front right lower forward position and compare the original arm length, mounting hole diameter, and bushing dimensions before installation. The ball joint uses a press-in mounting type and a threaded stud, so proper suspension service tools are required. Because mounting hardware is not included, reuse or source the correct hardware as needed. After installation, perform a wheel alignment to restore suspension geometry.

Quality Assurance

Delphi backs this assembly with OE-focused engineering practices, including dimensional and material analysis for fit consistency and durability testing in temperature extremes and salt spray. The part is built to standard replacement specifications for dependable service in Chrysler, Dodge, and Jeep suspension applications.
