Help bring back a smooth ride and predictable handling with the Dorman control arm 521-130, a front right upper assembly built as a direct replacement for the 2003-2006 Ford Expedition and 2003-2006 Lincoln Navigator. Dorman designed it to directly replace the original assembly, and put it through its evaluation process to support a smooth ride, directional stability and predictable dynamics. See the Buyer's Guide tab for engine details.
The upper control arm connects the steering knuckle to the frame. Its ball joint allows the wheel to pivot and steer, and its bushings let the arm move up and down with the suspension while holding the wheel in position.
This Dorman suspension control arm and ball joint assembly may be due for replacement if you notice clunking over bumps, loose or wandering steering, uneven tire wear, or cracked bushings. If a worn upper arm or ball joint is the cause, replacing the assembly replaces both at once. Inspect the suspension first, because other components can cause similar symptoms.
