Mevotech Supreme Suspension Control Arm and Ball Joint Assembly P/N:CMS80105
Restore tight, predictable steering and a solid front end with the Mevotech Supreme control arm CMK80721, a front left lower control arm and ball joint assembly that drops in as a direct-fit replacement for the 2006-2010 Ford Explorer, 2007-2010 Ford Explorer Sport Trac and 2006-2010 Mercury Mountaineer. This one-piece unit positions the wheel, controls suspension travel, and — through its integrated ball joint — lets the steering knuckle pivot for steering and ride motion.
Worn bushings or a loose ball joint can cause clunking or popping over bumps, wandering steering, and uneven tire wear. If a failed front left lower control arm or its ball joint is the cause, this Mevotech Supreme suspension control arm replaces both in a single unit.

Is this an upper or lower control arm?
This is the front left (driver's side) lower control arm with an integrated ball joint. It is not an upper arm.
Does it include the ball joint and any hardware?
Yes — the ball joint is built into the assembly, and a part-specific hex nut is provided to speed up ball joint installation.
What are the signs my Ford Explorer control arm needs replacing?
Clunking or popping over bumps, wandering steering, and uneven tire wear can point to worn control arm bushings or a loose ball joint. Diagnose the cause before replacing.
Do I need to replace both sides?
This listing is one front left lower unit. Suspension parts tend to wear at similar rates, so inspect the opposite side and replace it if worn for balanced handling.
