Steer with confidence on the DELPHI control arm and ball joint assembly TC4586, a direct-fit front left lower unit for the 2019-2022 Mercedes-Benz A220. Delphi applies its OE safety expertise to the aftermarket steering portfolio, so this arm and its integrated ball joint locate the wheel and let the suspension pivot through its travel.
OE-level validation: tested to the extreme — parts withstand temperatures below -40°C and over 120°C and endure 720 hours of salt spray, with extensive dimensional and material analysis for OE-to-aftermarket compatibility.
100% inspected: every control arm goes through complete crack detection and ultrasonic flaw detection so materials match OE specifications.
Precision ball stud: machined to micron tolerances for durability and smooth joint operation.
Consistent build: robot welding for repeatable quality, plus anti-corrosion protection applied to each part for corrosion prevention and enhanced appearance.
Signs the original arm or ball joint may need replacing include clunking or knocking over bumps, uneven tire wear, and loose or wandering steering. If a worn front left lower arm is the cause, this replaces it. Sold individually; replace the opposite side as needed for balanced handling.
