Detailed Description

Delphi TC6664 is engineered as a front right lower suspension control arm and ball joint assembly for 1993-1998 Nissan Quest, front right lower, 1995-1998 Mercury Villager, front right, and 1993-1994 Mercury Villager, front right lower. The stamped steel arm, rubber bushings, and pre-greased ball joint are specified for direct replacement service, while the bolt-in ball joint mounting and included hardware support a straightforward installation on the correct vehicle application. Delphi validates its steering and suspension parts through extreme temperature and salt-spray exposure testing, along with dimensional and material analysis, to help maintain OE-level compatibility. This part cross-references MOOG Chassis Products RK620341 for the same application.

Common Problems This Part Can Address

• Front-end looseness or wandering caused by worn control arm bushings
• Clunking or knocking from a worn lower ball joint
• Uneven tire wear related to suspension geometry wear
• Steering instability during braking or cornering
• Excessive play in the front right suspension assembly

Installation Notes and Tips

Verify the vehicle position before ordering, since this part is listed for front right and front right lower applications depending on model year. Inspect adjacent suspension components, alignment angles, and fasteners during replacement. Because the assembly is not adjustable and is not greaseable, install it as a complete replacement unit and follow the vehicle manufacturer’s alignment procedure after installation.

Quality Assurance

Delphi applies OE-based engineering and durability testing to its aftermarket steering and suspension portfolio. TC6664 is evaluated for temperature extremes and corrosion resistance, with additional dimensional and material checks to support consistent fitment on the listed Mercury Villager and Nissan Quest applications.
