Detailed Description

Delphi TC7974 is a rear upper forward suspension control arm made for vehicles that require OE-style fit and geometry in the rear suspension. Delphi applies dimensional and material analysis to match the original part as closely as possible, helping maintain proper suspension alignment and consistent handling characteristics. The part is built to withstand demanding temperature extremes and salt exposure testing used in Delphi’s OE validation process. This part cross-references MOOG Chassis Products RK642900 for the same application.

Vehicle coverage includes 2011-2022 Dodge Durango, 2011-2021 Jeep Grand Cherokee, and 2022 Jeep Grand Cherokee WK in the rear upper forward position. If you are replacing a worn rear upper forward control arm on a Jeep Grand Cherokee or Dodge Durango, Delphi TC7974 provides a direct replacement option for the specified applications.

Common Problems This Part Can Address

• Rear suspension clunking or knocking from a worn control arm
• Excessive play in the rear suspension linkage
• Uneven tire wear caused by suspension geometry issues
• Handling instability from a damaged rear upper forward arm
• Alignment concerns after control arm wear or failure

Installation Notes and Tips

Verify the rear upper forward position before installation and confirm vehicle fitment by year, make, and model. Because this control arm is non-adjustable, final suspension alignment should be checked after installation. Inspect related bushings and mounting points for wear before reassembly to avoid repeat repairs.

Quality Assurance

Delphi validates steering and suspension components through OE-focused testing, including extreme temperature exposure and extended salt spray resistance. TC7974 is built as a standard replacement part for the listed Dodge Durango and Jeep Grand Cherokee applications.
