Keep your front wheel firmly located and your steering pivoting smoothly with the Dorman - OE Solutions Front Left Upper Suspension Control Arm and Ball Joint Assembly 520-287. It installs as a direct-fit replacement for the 2002-2005 Ford Explorer, 2003-2005 Lincoln Aviator, and 2002-2005 Mercury Mountaineer, arriving as one pre-assembled unit to simplify the job.
The control arm locates the front wheel and lets the suspension travel up and down, while the ball joint allows the steering and suspension to pivot. If a worn or loose control arm or ball joint is behind your clunking over bumps, wandering steering, or uneven front tire wear, this assembly replaces it — diagnose the cause first.
