Delphi Suspension Control Arm and Ball Joint Assembly P/N:TC5177
Help keep your steering tight and precise with the Delphi control arm and ball joint assembly TC9129, a front right upper unit that installs as a direct-fit replacement on the 2016-2025 Mazda MX-5 Miata. This arm locates the wheel and provides a pivot for suspension travel, while the integrated ball joint lets the steering knuckle turn and articulate.
Clunking or popping over bumps, uneven tire wear, or loose, wandering steering can be signs a worn control arm or ball joint may need replacing; if a failed arm is the cause, this assembly replaces both in one part. Country of origin: Turkey.
