Mevotech Supreme Suspension Control Arm and Ball Joint Assembly P/N:CMS80105
Locate your front wheel and tie the steering knuckle to the chassis with the Mevotech Supreme control arm CMK90421 — a front left upper suspension control arm with a pre-assembled ball joint. It drops in as a direct-fit replacement across a range of 1992-1999 Mercedes-Benz models, from the 1992-1993 300SD to the 1994-1999 S500 and S600.
This Mevotech Supreme front left upper control arm integrates its ball joint into a single unit. Worn control arms and ball joints can show up as clunking over bumps, loose or wandering steering, and uneven tire wear; if the original arm or its ball joint is the cause, this replaces it. See the Buyer's Guide tab for the full engine-level fitment.
