Detailed Description

Delphi applies OE-focused engineering to its aftermarket steering and suspension portfolio, and TC3983 reflects that approach with careful dimensional and material analysis for proper fit and function. The assembly is built to handle demanding temperature extremes and corrosion exposure testing, helping support consistent performance in real-world driving conditions. This part cross-references MOOG Chassis Products RK623063 for the same application.

For drivers servicing a Nissan Pathfinder or Infiniti QX35/QX60 platform, this front right lower control arm assembly provides the key wear components in one unit. The aluminum construction, included bushings, and pre-installed ball joint help streamline suspension restoration while maintaining OE-style geometry.

Common Repair Uses

• Front-end clunking or knocking from worn suspension joints
• Uneven tire wear caused by loosened lower control arm components
• Steering pull or wandering related to worn bushings or ball joint wear
• Excessive suspension play during braking or cornering
• Restoration of front right lower suspension alignment on Infiniti and Nissan vehicles

Installation Notes and Tips

Install TC3983 only in the front right lower position listed in the fitment data. Because this assembly includes a ball joint and bushings, inspect the opposite side and related suspension components for matched wear before completing the repair. A professional alignment is recommended after installation to verify suspension geometry and steering response.
