Detailed Description
Delphi TC3986 is a suspension control arm and ball joint assembly for the front left lower position on the 2016-2022 Toyota Tacoma. The stamped steel arm uses a painted black finish and includes the ball joint, bushings, dust boot, mounting hardware, and locking nut for a complete replacement assembly. Delphi applies OE dimensional and material analysis to help maintain proper fit and suspension alignment on the Tacoma platform. This part cross-references MOOG Chassis Products RK623414 and Mevotech Supreme CMS861297 for the same application.
Common Repair Symptoms
- Front-end clunking or knocking 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 to the lower control arm
Installation Notes
Install TC3986 on the front left lower position only. Because the ball joint is press-in and the arm is non-adjustable, proper removal and installation tools are important for a clean service job. After installation on a Toyota Tacoma, verify alignment and inspect adjacent suspension components for wear before returning the vehicle to service.
Quality Assurance
Delphi subjects its steering and suspension parts to extreme temperature and salt-spray testing, along with dimensional and material checks to support OE-level fit and durability. The TC3986 is built using Delphi’s OE-focused engineering approach for the Toyota Tacoma front left lower suspension position.
