Detailed Description

Delphi TC5890 is a rear suspension control arm designed for the rear right upper rearward location on the Buick Enclave, Chevrolet Traverse, GMC Acadia, GMC Acadia Limited, and Saturn Outlook. Delphi applies OE-focused dimensional and material analysis to aftermarket steering and suspension parts, helping maintain proper fit and suspension alignment characteristics. The steel arm construction and rubber bushings support everyday road use, while the included hardware simplifies replacement work during rear suspension repair.

This part cross-references Dorman OE Solutions 521-966 and 523-047 for the same application. It also cross-references part numbers 25788291 and CA90558. Use Delphi TC5890 when replacing a worn rear upper control arm on a 2007-2016 GMC Acadia, 2008-2017 Buick Enclave, or 2009-2017 Chevrolet Traverse.

Common Problems This Part Addresses

• Rear suspension clunking from worn control arm bushings
• Excessive rear wheel movement caused by a fatigued arm
• Uneven tire wear related to rear suspension geometry issues
• Loose or unstable rear-end handling from worn suspension joints and bushings
• Corrosion or damage to the original rear upper control arm

Installation Notes and Tips

Replace the control arm on the rear right upper rearward position only when the vehicle is safely supported and the suspension is unloaded as required by service procedure. Because this arm uses rubber bushings and is not adjustable, final alignment should be checked after installation. Verify vehicle application by year, make, model, and rear right upper rearward position before ordering Delphi TC5890.

Quality Assurance

Delphi subjects OE-style steering and suspension components to extreme temperature testing below -40 degrees C and above 120 degrees C, along with 720 hours of salt spray exposure. That testing, combined with dimensional and material analysis, supports consistent fit and durability for replacement service.
