Common Problems This Part Can Address

• Excessive rear suspension play from a worn control arm or ball joint
• Clunking or knocking noises from the rear suspension area
• Uneven tire wear caused by suspension geometry issues
• Reduced directional stability during braking or cornering
• Loose or inconsistent rear-end handling on the listed INFINITI models

Installation Notes and Tips

Verify vehicle fitment by year, model, and rear right upper position before installation. The ball joint is already installed, and the assembly is pre-greased, which simplifies replacement work. Because this is a press-in style ball joint assembly, proper suspension service procedures and alignment checks should be followed after installation. Confirm mounting hole size and hardware compatibility during removal and replacement.

Quality Assurance

Dorman subjects this control arm and ball joint assembly to an industry-focused evaluation process to help ensure proper fit and consistent suspension performance. The design follows the original equipment layout for the listed applications and uses materials selected for everyday light-duty suspension service.
