Steer straight and keep the front suspension tight with the Delphi Suspension Control Arm and Ball Joint Assembly (TC3986), a direct-fit Tacoma lower control arm for the 2016-2022 Toyota Tacoma. It installs in the front left (driver's side) lower position, locating the wheel and integrating the ball joint that lets the knuckle pivot for steering. If a worn control arm or ball joint is behind your clunking, wandering steering, or uneven tire wear, this assembly replaces the failed original.
Built to OE expertise: Delphi applies its OE steering knowledge to the aftermarket, with extensive dimensional and material analysis for close OE-to-aftermarket compatibility.
Extreme testing: parts withstand temperatures below -40°C and over 120°C and are exposed to 720 hours of salt spray.
Verified materials: 100% crack detection and ultrasonic flaw detection help ensure materials match OE specifications.
Precision ball stud: ball studs machined to micron tolerances for durability and smooth joint operation.
Consistent build: robot welding for repeatable quality, with anti-corrosion protection applied to each part for corrosion prevention and enhanced aesthetics.
