Keep your steering tight and your tires tracking true with the DELPHI control arm and ball joint assembly, part number TC4408. This front left lower unit drops in as a direct-fit replacement for the 2017-2024 Mazda CX-5, locating the wheel and providing the pivot for smooth steering and suspension travel. Delphi applies its OE engineering expertise to its aftermarket steering portfolio, with extensive dimensional and material analysis to match the OE part.
Worn control arm bushings or a failing lower ball joint can cause clunking over bumps, uneven tire wear, and loose steering — if that is the cause on your CX-5, this assembly replaces the front left lower arm and joint together. This is a lower control arm for the Mazda CX-5 sold as a complete assembly.
