Replace a worn front right lower arm in one step with the Dorman OE Solutions 520-866, a Mazda 3 control arm for the 2004-2009 Mazda 3 that also fits the 2009 Mazda 3 Sport and the 2006-2010 and 2012-2017 Mazda 5. Dorman designs it as a direct replacement for the original equipment on these applications. See the Buyer's Guide tab for engine details.
As a Dorman suspension control arm and ball joint assembly, this part connects the wheel's steering knuckle to the chassis. It lets the suspension travel up and down while holding the wheel in position, and the ball joint gives the knuckle its steering pivot.
- Direct replacement: takes the place of the original assembly on specific vehicle applications.
- Complete repair: the ball joint and bushings come pre-installed, which saves time and labor.
- Tested: Dorman's evaluation process is aimed at a smooth ride, directional stability and predictable dynamics.
- Corrosion protection: additional coatings help the arm resist rust and corrosion.
Signs this part may need replacing: clunking over bumps, loose or wandering steering, uneven tire wear, or play in the ball joint. If a worn arm, bushing or ball joint is the cause, this assembly replaces all three at once.
Use the vehicle service information to choose the correct fasteners and to find out whether the originals can be reused. Have the wheel alignment checked after installation.
