Delphi Suspension Control Arm and Ball Joint Assembly P/N:TC5770
$149.99

Restore precise steering and secure suspension geometry with the Delphi Suspension Control Arm and Ball Joint Assembly (TC5770). This front right lower unit installs as a direct-fit replacement for the 2005-2010 Ford Mustang (see the Buyer's Guide tab for engine-level fitment), combining the control arm and its integrated ball joint into one assembly that locates the wheel and lets the suspension pivot through its travel. Worn control-arm bushings or a loose ball joint can cause clunking over the road, uneven tire wear, and imprecise steering — if the original arm or joint is the cause, this replaces it.

  • OE-derived engineering: Built on Delphi's OE expertise, with extensive dimensional and material analysis for close OE-to-aftermarket compatibility. Tested to the extreme — withstands temperatures below -40°C and over 120°C and 720 hours of salt spray.
  • Verified materials: Undergoes 100% crack detection and ultrasonic flaw detection so materials match OE specifications.
  • Precision ball studs: Ball studs are machined to micron tolerances for durability and smooth joint operation.
  • Robot-welded & protected: Robot welding gives consistent quality, and anti-corrosion protection is applied to each part for corrosion prevention and enhanced aesthetics.
