Detailed Description

Delphi TC4793 is a front right lower suspension control arm and ball joint assembly developed for select Nissan LEAF and Nissan Sentra models. The arm uses stamped steel construction, a grooved ball joint stud, and press-in ball joint mounting for a service-ready replacement. Delphi applies OE-focused dimensional and material analysis to support proper fitment, while the assembly is tested for temperature extremes and salt-spray exposure to help validate durability in demanding conditions. The part number TC4793 is a direct reference for ordering and catalog lookup.

This part cross-references MOOG Chassis Products RK621156 for the same application.

What It Helps Fix

• Front-end looseness or wandering from worn control arm bushings
• Clunking or knocking from a worn ball joint
• Uneven tire wear caused by suspension play
• Steering instability on the front right lower corner
• Suspension noise during braking, turning, or road impacts

Installation Notes and Tips

Verify vehicle year, model, and front right lower position before installation. Because the ball joint is press-in and the assembly is not greaseable, replacement is typically performed as a complete unit rather than serviced piecemeal. Always inspect adjacent suspension components, fasteners, and alignment settings after installation. Professional alignment is recommended after replacing a control arm assembly.

Quality Assurance

Delphi uses OE-based engineering practices for its aftermarket steering and suspension portfolio. This assembly is evaluated through dimensional and material analysis and exposed to extreme temperature and corrosion testing to support consistent replacement quality. Part number TC4793 is built as a standard replacement component for the listed Nissan applications.
