Keep your front suspension tight and your steering precise with the Mevotech Supreme control arm and ball joint assembly, MPN CMK90423. This front left upper unit combines the control arm with an integrated ball joint, locating the wheel and allowing it to pivot and travel while helping keep the tire in proper contact with the road. It installs as a direct-fit replacement for the listed applications, including the 1998-2003 Mercedes CLK320 control arm, 1999-2003 Mercedes CLK430 control arm, 1994-2000 C280, 1996-2003 E320, and 1998-2004 SLK230 — see the Buyer's Guide tab for the full list.
This is a Mevotech Supreme suspension control arm for high-usage passenger, commercial, and fleet vehicles. If a worn arm or ball joint is behind clunking over bumps, loose or wandering steering, or uneven tire wear, replacing it addresses that cause. Sold individually as the front left upper unit; inspect the opposite side and replace in pairs as directed by the service procedure.
Does this control arm and ball joint assembly include the ball joint?
Yes. The CMK90423 is a one-piece assembly with the ball joint integrated into the control arm, so you replace both together in a single unit.
What position on the vehicle does CMK90423 fit?
It is the front left (driver's side) upper control arm. It is sold individually; check the opposite side and replace both together for balanced results.
Which vehicles does this part fit?
It fits many 1994-2004 Mercedes-Benz models, including the CLK320, CLK430, C280, E320, E430, and SLK230. See the Buyer's Guide tab for the complete year-by-year list.
Is mounting hardware included?
A part-specific nylon locking nut is provided to speed ball joint installation. Consult the vehicle service information for any other fasteners and whether they may be reused.
What are signs this control arm may need replacing?
Clunking over bumps, loose or wandering steering, and uneven tire wear can point to a worn control arm or ball joint. Diagnose the cause first, then replace if this part is at fault.
