Detailed Description

Dorman 521-274 is a suspension control arm and ball joint assembly engineered for the front right lower suspension position on select INFINITI FX35 and INFINITI FX45 models. It uses an iron control arm with rubber bushings, a press-in ball joint mounting type, and a pinch-style stud design to match the original suspension layout. The assembly is pre-greased, includes the ball joint already installed, and is supplied with mounting hardware for a more complete replacement. Dorman 521-274 is evaluated to help restore consistent suspension response, road feel, and directional control in the affected applications.

This part cross-references Delphi TC5540 for the same application.

What It Helps Address

• Clunking or knocking from the front suspension
• Excessive play in the lower control arm assembly
• Uneven steering response or wandering at speed
• Worn rubber bushings affecting suspension control
• Ball joint wear at the front right lower corner

Installation Notes and Tips

Verify vehicle year, model, and front right lower position before installation. Because the ball joint is press-in and already installed, replacement should follow the correct suspension service procedure and torque specifications for the application. Inspect adjacent suspension components, alignment settings, and mounting points during service to help ensure proper operation after installation.
