Replace a worn upper control arm, ball joint and bushings in one step with this Dorman control arm, part number 521-355, built for the front left upper position on the 2006-2010 Ford Explorer, 2007-2010 Ford Explorer Sport Trac and 2006-2010 Mercury Mountaineer. It is a direct replacement for the original equipment on these applications. The ball joint and bushings come already installed, which saves time and labor.
The Dorman suspension control arm and ball joint assembly connects the wheel assembly to the vehicle's chassis. This lets the suspension move up and down while helping keep the wheel in position. The ball joint gives the steering knuckle a pivot point for turning.
- Direct replacement: Designed to take the place of the original assembly on the listed applications.
- Ready to install: Arrives with the ball joint and bushings pre-installed, so there are fewer steps during installation.
- Tested design: Went through Dorman's industry-leading evaluation process, which aims for a smooth ride, directional stability and predictable dynamics.
- Corrosion protection: Additional coatings help it resist rust and corrosion.
A worn control arm may show up as clunking or knocking over bumps, loose or wandering steering, uneven tire wear, or cracked and torn bushings. Have the suspension inspected to confirm the cause before you replace parts. This listing covers the front left upper position, and replacing both sides together is recommended. See the Buyer's Guide tab for engine-specific fitment.
