Detailed Description

Delphi TC3963 is a front right suspension control arm and ball joint assembly for Subaru Legacy and Subaru Outback models from 2010 through 2014. The assembly uses stamped steel construction and includes the ball joint, rubber bushings, dust boot, and mounting hardware for a complete front suspension service part. The ball joint uses a threaded stud and bolt-in mounting style, while the arm is pre-greased and non-greaseable for straightforward replacement service. Part number TC3963 is engineered for power steering applications and is built to match OE dimensional and material requirements for fit and function.

This part cross-references MOOG Chassis Products RK623343 and Mevotech Supreme CMS801115 for the same application.

Common Repair Uses

• Front-end clunking or looseness from a worn control arm assembly
• Ball joint play affecting steering response and tire wear
• Cracked or deteriorated bushings in the front right suspension
• Dust boot damage that exposes the ball joint to contamination
• Restoring proper suspension alignment after component wear

Installation Notes and Tips

Install TC3963 on the front right side only for the listed Subaru Legacy and Subaru Outback fitments. Verify the threaded stud orientation, mounting hole alignment, and bushing dimensions before installation. Because this is a complete control arm and ball joint assembly, inspect adjacent suspension components, fasteners, and alignment settings during service. A professional wheel alignment is recommended after replacement.

Quality Assurance

Delphi subjects steering and suspension parts to extreme temperature cycling and extended salt-spray exposure, along with dimensional and material analysis to support OE-level fit and durability expectations. Part number TC3963 reflects Delphi's OE-focused aftermarket engineering for Subaru Legacy and Subaru Outback front suspension service.
