Description

Restore precise handling and steady wheel control with the Delphi control arm and ball joint assembly, MPN TC3884. This front left lower unit locates the wheel and pivots on an integrated ball joint, and it drops in as a direct-fit replacement for the 2015-2018 BMW M3, the 2015-2020 BMW M4, and the 2016-2018 and 2020 BMW M2. See the Buyer's Guide tab for engine specifics.

OE-derived testing: Delphi's OE safety technology is applied to its aftermarket steering portfolio, with parts tested below -40°C, above 120°C, and through 720 hours of salt spray, plus dimensional and material analysis for OE compatibility.
Verified materials: 100% crack detection and ultrasonic flaw detection help confirm materials match OE specifications.
Precision joint: ball studs machined to micron tolerances for durable, smooth joint operation.
Built for consistency: robot welding for uniform quality, with anti-corrosion protection applied for corrosion prevention and appearance.

Worn control arm bushings or a failing ball joint can cause clunks, wandering steering, or uneven tire wear; if the original arm is the cause, this replaces it.

Clunking over inputs, wandering or loose steering, and uneven tire wear can indicate worn bushings or a failing ball joint. Have the cause diagnosed before replacing.
