Mevotech Supreme Suspension Control Arm and Ball Joint Assembly P/N:CMS30121
Keep your front suspension tight and your steering precise with the Mevotech Supreme control arm CMS40190, a direct-fit replacement for the 1994-2004 Ford Mustang. This front left lower control arm and ball joint assembly locates the wheel, lets the suspension pivot through its travel, and — through the integrated ball joint — allows the steering knuckle to swivel as you turn and the wheel to move over bumps. Mevotech Supreme parts are engineered in-house with application-specific upgrades aimed at higher durability, built for high-usage passenger vehicles, fleets and working trucks.
A protective surface treatment resists rust build-up for added longevity. If a worn lower control arm or ball joint is behind your Mustang's clunking over bumps, steering wander, or uneven tire wear, this assembly replaces it. Search shoppers also know this as a lower control arm Mustang or simply a Mustang control arm.
Does this control arm fit my vehicle?
It is a direct-fit replacement for the 1994-2004 Ford Mustang, front left lower position. Check the Buyer's Guide tab to confirm it matches your specific Mustang.
Is the ball joint included in this assembly?
Yes. This part ships as an assembly with the ball joint already installed, plus the part-specific castle nut and cotter pin needed to secure it to the vehicle.
Can this control arm be greased?
Yes. It includes a 180-degree SAE grease fitting, so you can lubricate the joint during service to help maintain smooth, long-lasting operation.
What are the signs of a worn control arm or ball joint?
Common signs include clunking or knocking over bumps from the front suspension, steering wander, looseness, and uneven front tire wear. Diagnose the cause before replacing.
Should I replace the other side too?
This assembly covers the front left lower position and is sold individually. Replacing the right side at the same time is a good idea if it shows similar wear, for balanced handling.
