This Dorman suspension control arm and ball joint assembly is built as a direct replacement for the original assembly on the listed applications. Dorman puts it through an industry-leading evaluation process intended to deliver a smooth ride, directional stability and predictable dynamics.

• Trustworthy replacement: designed to take the place of the original assembly on the listed trucks and SUVs.
• Ready-to-install repair: the ball joint and bushings come pre-installed, which helps save time and labor during the job.
• Quality engineering: the assembly went through industry-leading testing aimed at a smooth, stable and safe ride.
• Corrosion protection: additional coatings provide rust and corrosion resistance.

Signs that a lower control arm or its ball joint may need replacing include clunking over bumps, wandering or loose steering, uneven tire wear and noticeable play at the ball joint. If a worn arm, ball joint or bushing is the cause, this assembly replaces all three at once. Replacing the left and right lower arms together is recommended for balanced handling.
