Help keep your front suspension steady and predictable with the Dorman control arm 528-078, a front right lower control arm with ball joint that directly replaces the original equipment on the 2008-2009 Ford Taurus and 2008-2009 Mercury Sable. Each Dorman suspension control arm and ball joint assembly arrives with the ball joint and bushings already installed, so you don't have to source and fit those components separately.
- Direct replacement: Takes the place of the original assembly on the listed applications.
- Ready to install: The ball joint and bushings come pre-installed, saving time and labor.
- Tested for ride quality: Put through Dorman's industry-leading evaluation process, which is designed to deliver a smooth ride, directional stability and predictable dynamics.
- Added corrosion protection: Additional coatings help resist rust and corrosion.
As the Dorman lower control arm for this position, it links the wheel assembly to the chassis and pivots on its bushings as the suspension moves. The ball joint lets the knuckle steer and travel. Signs this part may need replacing include clunking over bumps, loose or wandering steering, uneven tire wear, or a torn ball joint boot.
This listing is for one assembly, for the front right lower position. Replacing both sides together is recommended for balanced handling. See the "Vehicles it fits" section for engine-level fitment.

What comes with this assembly?
Each assembly includes the control arm with its ball joint and bushings already installed, so those components don't have to be fitted separately.
What does a lower control arm do?
It connects the wheel assembly to the chassis and pivots on its bushings as the suspension moves. The ball joint lets the knuckle steer and travel.
What are signs this part may need replacing?
Clunking over bumps, loose or wandering steering, uneven tire wear, or a torn ball joint boot can indicate a worn control arm or ball joint. Have the suspension inspected to confirm the cause.
Should the alignment be checked after installation?
Yes. Replacing a control arm can change the suspension geometry, so a wheel alignment check is recommended. Follow the vehicle service information for torque specs and procedures.
