The Story
OE-Style Front Right Lower Control Arm
Delphi TC3979 is a front right lower suspension control arm and ball joint assembly built for direct replacement service on select Nissan applications. It combines a stamped steel arm, pre-greased ball joint, and included bushings to support precise front suspension geometry on the Frontier and Xterra.
Fits 2014-2019 Nissan Frontier, front right lower. Fits 2014-2015 Nissan Xterra, front right lower.
- Stamped steel control arm with painted black finish
- Pre-greased ball joint included with press-in mounting type
- Grooved ball joint stud design
- Bushings included with rubber construction
- Dust boot included with chloroprene rubber material
- Mounting hardware included
- Premium grade replacement for front suspension service
- Designed for power steering applications
Detailed Product Overview
Delphi TC3979 is engineered as an OE-style suspension control arm and ball joint assembly for the front right lower position. It uses stamped steel construction for strength, a black painted finish for corrosion resistance, and a press-in ball joint design with a grooved stud. The assembly includes bushings, a dust boot, and mounting hardware, helping streamline replacement on 2014-2019 Nissan Frontier and 2014-2015 Nissan Xterra models. Delphi applies dimensional and material analysis to improve OE-to-aftermarket fit, and the part is tested across extreme temperature and salt-spray exposure conditions to verify durability.
This part cross-references MOOG Chassis Products RK620371 for the same application.
Common Replacement Reasons
- Front-end clunking or popping over bumps
- Uneven tire wear from worn suspension geometry
- Loose or wandering steering feel
- Excessive play from a worn ball joint or bushings
- Visible cracking, corrosion, or damage in the lower control arm
Installation Notes
Install in the front right lower position only. Verify vehicle year, model, and suspension configuration before installation on Nissan Frontier or Nissan Xterra. Because the ball joint is press-in, proper suspension tools and alignment service are recommended after replacement. Inspect the mating components, fasteners, and steering linkage for wear before completing the job.
Quality Assurance
Delphi builds this assembly using OE-focused engineering and validation methods, including dimensional and material checks for fit consistency. The part is also subjected to temperature cycling and salt-spray testing to evaluate performance in demanding conditions.
