Detailed Description

Delphi TC7902 is a rear right upper suspension control arm for 2010-2012 Buick LaCrosse, 2011-2012 Buick Regal, 2010-2011 Saab 9-5, and 2010 Buick Allure. Delphi applies OE-level dimensional and material analysis to support proper fit and consistent suspension geometry, and the part is tested across extreme temperature and salt-spray conditions to evaluate durability in demanding environments. If you are replacing a worn rear suspension arm on a Buick LaCrosse, Buick Regal, or Saab 9-5, TC7902 provides a direct-fit service part for the rear right upper location.

This part cross-references Dorman - OE Solutions 522-918 for the same application.

Common Repair Symptoms

• Rear suspension clunking or knocking over bumps
• Uneven rear tire wear from worn suspension geometry
• Excessive rear-end looseness or instability
• Cracked or deteriorated control arm bushings
• Noise during braking, cornering, or road transitions

Installation Notes

Verify rear right upper placement before installation and compare the original arm for bushing orientation and mounting points. Because mounting hardware is not included, reuse or replace fasteners as needed during service. A professional alignment is recommended after suspension work to confirm rear geometry and tire wear settings.

Quality Assurance

Delphi uses OE-focused engineering, dimensional checks, and material analysis to support aftermarket fitment. The brand also subjects steering and suspension components to temperature extremes and extended salt-spray exposure during validation.
