Keep the rear suspension tightly located and pivoting smoothly with the Mevotech Supreme control arm CMS861248, a rear upper control arm and ball joint assembly that installs as a direct-fit replacement for the 2001-2006 Lexus LS430 and 2002-2006 Lexus SC430. The arm positions the wheel through its range of travel while the integrated ball joint pivots to allow suspension movement—so this is the part to reach for when you search for a 2001-2006 Lexus LS430 rear upper control arm.

  • Steel tube construction: built to OE-level tolerances for strength.
  • Sintered bearings: engineered for longer-lasting performance.
  • Serviceable design: includes a 90-degree SAE grease fitting for easy lubrication.
  • Locked-in fit: added knurling locks the control arm bushing to the sub-frame.
  • Faster install: a part-specific hex nut speeds ball joint installation, and pre-applied nylok thread adhesive keeps fasteners secure and vibration-resistant.
  • Corrosion resistance: a protective surface treatment helps prevent rust build-up.

This Mevotech Supreme suspension control arm is engineered for high-usage passenger, fleet and working vehicles. Worn control arms or ball joints can produce clunks, loose handling, and uneven tire wear; if a worn original is the cause, this 2001-2006 Lexus LS430 control arm assembly is designed to replace it.

Yes. It includes a 90-degree SAE grease fitting for servicing, a part-specific hex nut for the ball joint, and pre-applied nylok thread adhesive on the fasteners.

What are signs my control arm or ball joint may need replacing?
