Mevotech Supreme Suspension Control Arm and Ball Joint Assembly P/N:CMS501030
Keep your BMW's front suspension tight and precise with the Mevotech Supreme control arm (CMK9123), a front left lower unit with an integrated ball joint that installs as a direct-fit replacement for the 1975-1978 BMW 530I, 1977 BMW 630CSI, 1979-1981 BMW 528I, and 1979-1982 BMW 633CSI [All engines]. It locates the front wheel and, through its ball joint, lets the wheel steer and travel while helping hold alignment.
The Mevotech Supreme suspension control arm connects the front subframe to the steering knuckle. Worn arms or ball joints can show up as clunking or knocking over bumps, uneven front tire wear, or loose, wandering steering. If a failed control arm or ball joint is the cause, this Mevotech Supreme lower control arm replaces it. Shoppers cross-shopping a BMW 528i control arm will find this covers that model along with the other listed applications. Country of origin: Turkey.
