This Delphi TC6610 control arm is built for rear suspension service on Jeep Commander and Jeep Grand Cherokee applications where the original upper arm has worn, bent, or developed excess play. Delphi applies OE-style dimensional and material analysis to support proper part-to-vehicle compatibility, and the part is tested across extreme temperature ranges and salt-spray exposure to evaluate durability in demanding conditions. This part cross-references MOOG Chassis Products RK641865 for the same application.

Common Replacement Reasons

• Rear suspension clunking or knocking over bumps
• Uneven tire wear caused by worn rear suspension geometry
• Excess rear wheel movement from a fatigued control arm
• Corrosion or structural damage to the original arm
• Restoring stable rear upper suspension location on Jeep Commander and Jeep Grand Cherokee models

Installation Notes

Verify rear upper fitment before installation on 2006-2010 Jeep Commander and 2005-2010 Jeep Grand Cherokee models. Because bushings, mounting hardware, and grease fittings are not included, inspect related components and reuse or replace them as needed during service. A professional alignment check is recommended after suspension work to confirm correct rear geometry.

Quality Assurance

Delphi uses OE-based engineering, dimensional checks, and material analysis to support fit and function. The part is also evaluated under extreme cold and heat, along with extended salt-spray exposure, to assess durability in real-world conditions.
