• Front right position for select Ford Taurus, Lincoln MKT, Lincoln MKS, and Ford Flex models
• Pre-greased assembly with included ball joint, bushings, dust boot, mounting hardware, and locking nut
• Cast iron control arm construction with painted black finish
• Press-in ball joint with threaded stud for OE-style service replacement
• Rubber bushings and chloroprene rubber dust boot for suspension isolation
• Non-adjustable design with power steering application fitment

OE-Style Fit and Construction

Delphi TC3975 is engineered as a premium suspension control arm assembly for the front right side. The cast iron arm uses a casting/forged construction and includes the ball joint already installed, along with bushings and a dust boot for a complete replacement unit. Delphi applies OE dimensional and material analysis to help maintain proper fitment on the front suspension of the Ford Taurus, Lincoln MKT, Lincoln MKS, and Ford Flex. This part cross-references MOOG Chassis Products RK622917 for the same application.

Common Problems This Part Can Address

• Clunking or knocking from the front suspension
• Excessive play in the front right control arm or ball joint
• Uneven tire wear caused by worn suspension components
• Steering wander or reduced front-end stability
• Cracked, dry-rotted, or separated control arm bushings

Installation Notes and Tips

Verify front right fitment by year, make, and model before installation. Because this assembly uses a press-in ball joint and threaded stud, inspect the mating hardware and surrounding suspension components for wear before reassembly. A professional alignment is recommended after replacement to restore proper suspension geometry.

Quality Assurance

Delphi subjects steering and suspension components to extreme temperature testing below -40 degrees C and above 120 degrees C, along with extended salt-spray exposure and dimensional checks to support OE-level fit and durability expectations.
