Bring your front suspension back to a tight, controlled feel with the Delphi control arm (TC6339), a front right lower control arm and ball joint assembly built for the 2006-2011 Buick Lucerne and 2006-2011 Cadillac DTS. It locates the wheel and, through its integrated ball joint, lets the suspension and steering move while keeping the wheel properly positioned.

  • Tested for OE performance: Delphi applies its OE expertise to its aftermarket steering portfolio, testing parts to withstand temperatures below -40°C and over 120°C plus 720 hours of salt spray, with dimensional and material analysis for compatibility between the OE and aftermarket part.
  • Verified materials: undergoes 100% crack detection and ultrasonic flaw detection so materials match OE specifications.
  • Precision ball stud: ball studs are machined to micron tolerances for durability and smooth joint operation.
  • Robot-welded and protected: robot welding delivers consistent quality, and anti-corrosion protection is applied for corrosion prevention and enhanced aesthetics.

Clunking over bumps, loose or wandering steering, and uneven tire wear can be signs the original control arm bushings or ball joint may be worn. If a failed front right lower control arm is the cause, this assembly replaces it as a direct-fit for the listed applications. See the Buyer's Guide tab for engine details.
