Detailed Description

Delphi TC8309 is a suspension control arm and ball joint assembly engineered for the rear right upper position on Subaru Outback vehicles from 2010 through 2019. It is built from cast iron with a casting/forged construction and finished in paint for service-ready corrosion protection. The assembly includes the ball joint, bushings, and dust boot, and it arrives pre-greased for installation.

This part cross-references MOOG Chassis Products RK623394 and Mevotech Supreme CMS801200 for the same application. If you are replacing a worn rear upper control arm on a Subaru Outback, TC8309 provides the correct fitment for the rear right upper location and supports OE-style suspension restoration.

Common Repair Uses

• Clunking or knocking from the rear suspension
• Excessive play from a worn ball joint
• Cracked or deteriorated control arm bushings
• Uneven rear tire wear caused by suspension looseness
• Restoring rear suspension geometry on a Subaru Outback

Installation Notes

Install TC8309 at the rear right upper position only. Verify the vehicle year and suspension layout before replacement, and inspect adjacent bushings, links, and mounting points for wear during service. Because mounting hardware is not included, reuse or source the correct hardware separately as needed.

Quality Assurance

Delphi subjects steering and suspension components to OE-focused validation, including temperature extremes below -40 degrees C and above 120 degrees C, plus 720 hours of salt-spray exposure. The brand also uses dimensional and material analysis to improve OE-to-aftermarket fit consistency for Subaru Outback suspension service.
