Delphi Suspension Control Arm and Ball Joint Assembly P/N:TC3150
$119.99

Keep the front suspension located and articulating with the Delphi control arm TC3150, a front right lower rearward control arm and ball joint assembly built with Delphi's OE safety technology. It installs as a direct-fit replacement for the 2017-2022 Land Rover Discovery, the 2014-2015 and 2018-2020 Land Rover Range Rover, and the 2014-2017 Land Rover Range Rover Sport. See the Buyer's Guide tab for the full engine coverage.

The arm positions the front right lower rearward suspension while its integrated ball joint lets the wheel steer and travel through its range of motion.

  • Tested to the extreme: withstands temperatures below -40°C and over 120°C plus 720 hours of salt spray, with extensive dimensional and material analysis for OE-to-aftermarket compatibility.
  • Verified materials: 100% crack detection and ultrasonic flaw detection help ensure materials match OE specifications.
  • Precision ball studs: machined to micron tolerances for durability and smooth joint operation.
  • Robot-welded & protected: robot welding for consistent quality, plus anti-corrosion protection applied to each part.

Signs this assembly may need replacing include clunking over the front suspension on acceleration or bumps, loose or wandering steering, or uneven front tire wear — diagnose the cause before replacing. Replace worn suspension parts as your vehicle service information directs.
