Bring OE-grade steering and suspension geometry back to your ride with the Delphi control arm TC6634, a direct-fit replacement for the 2007-2012 Lexus LS460. This is the front right lower rearward control arm, and it drops into that exact position to locate the wheel and connect the suspension to the vehicle's structure through its integrated ball joint. If the original arm's bushings or ball stud have worn — signs include clunking on acceleration, deceleration or over bumps, loose or wandering steering, and uneven tire wear — this Delphi unit replaces it.
- OE-validated durability: Delphi applies its OE steering expertise to the aftermarket, testing parts below -40°C and above 120°C and exposing them to 720 hours of salt spray, with dimensional and material analysis for OE-to-aftermarket compatibility.
- 100% inspected: every arm undergoes complete crack detection and ultrasonic flaw detection so materials match OE specifications.
- Robot welded: control arms use robotic welding for consistent quality.
- Precision ball stud: the ball studs are machined to micron tolerances for durability and smooth joint operation, with anti-corrosion protection applied for corrosion prevention and enhanced appearance.
Fits the 2007-2012 Lexus LS460 in the front right lower rearward position.
