Mevotech Supreme Suspension Control Arm and Ball Joint Assembly P/N:CMK80387
Keep the front end tight and the steering precise with the Mevotech Supreme control arm and ball joint assembly (CMS86105), a front left (driver's side) upper unit that installs as a direct-fit replacement on the 1998-2005 Lexus GS300, 1998-2000 Lexus GS400, 2001-2005 Lexus GS430, and 2002-2010 Lexus SC430. The control arm locates the wheel and connects the steering knuckle to the vehicle, while the integrated ball joint lets the knuckle pivot and travel as the suspension and steering move.
Signs the original may need replacing include clunking or knocking from the front suspension, imprecise or wandering steering, and uneven front tire wear. If a worn arm or ball joint is the cause, this assembly replaces both in a single part.

Does this Mevotech Supreme suspension control arm fit my Lexus?
It's a direct-fit replacement for the 1998-2005 GS300, 1998-2000 GS400, 2001-2005 GS430, and 2002-2010 SC430. Check the Buyer's Guide tab to confirm your exact year and model.
What position is this GS300 control arm?
It's the front left (driver's side) upper control arm with an integrated ball joint.
Can the ball joint be greased and serviced?
Yes. It includes a 180-degree SAE grease fitting for servicing, and ships with a slotted castle nut and easy-snap cotter pin for installation.
Should I replace the other side too?
Suspension parts on an axle wear at a similar rate, so inspecting and, if needed, replacing the opposite-side arm is good practice for balanced handling. This listing is for one assembly.
What is this control arm made of?
Forged steel with a protective surface treatment that helps resist rust and corrosion, built to meet or exceed OE specifications.
