This Dorman suspension control arm and ball joint assembly is built as a direct replacement for the original equipment. It links the wheel's steering knuckle to the vehicle's frame. The arm pivots on its bushings as the suspension moves, and the ball joint lets the knuckle steer and travel.

- Tested by Dorman: Went through an industry-leading evaluation process aimed at a smooth ride, directional stability and predictable dynamics.
- Added coatings: Extra coatings provide rust and corrosion resistance.
Signs this part may need replacing include clunking over bumps, loose or wandering steering, and uneven tire wear. Other suspension parts can cause the same symptoms, so diagnose the cause before replacing anything. Replacing both sides together is recommended for even, balanced handling. Have the wheel alignment checked after installation.
