Replace a worn front right upper arm in one step with the Dorman control arm 521-950, a direct replacement for the original equipment on the 2006-2010 Hummer H3 and the 2009-2010 Hummer H3T. For engine details, see the "Vehicles it fits" section.
This Dorman suspension control arm and ball joint assembly arrives with the ball joint and bushings already installed. The arm links the steering knuckle to the frame so the wheel can travel up and down while staying located, and the ball joint gives the knuckle its steering pivot.
- Trustworthy replacement: built to take the place of the original assembly on the listed applications.
- Complete repair: the ball joint and bushings come pre-installed, saving time and labor.
- Quality engineering: put through an industry-leading testing process aimed at a smooth, stable ride with predictable dynamics.
- Corrosion protection: additional coatings provide rust and corrosion resistance.
Clunking over bumps, loose or wandering steering, uneven tire wear, or play in the ball joint are signs this arm may need replacing. Other suspension parts can cause similar symptoms, so diagnose the cause first. This control arm with ball joint is sold individually for the front right upper position. Replacing the left and right sides together is recommended, and have the wheel alignment checked after installation.
