• Rubber bushings included
• Welded ball joint with threaded stud
• Mounting hardware included
• Standard replacement part number TC2128

Detailed Description

Delphi TC2128 is engineered for the front right lower position on the Dodge Sprinter 2500 and Dodge Sprinter 3500. The control arm uses a boxed steel construction with a welded ball joint and rubber bushings to restore suspension support and steering response in the original mounting location. Delphi applies OE-level dimensional and material analysis to help ensure proper compatibility with the factory suspension layout, and the part is tested across extreme temperature and salt-spray conditions to verify durability in demanding environments. This part cross-references Dorman OE Solutions 521-438 for the same application.

Common Issues This Part Can Address

• Excessive front-end looseness or wandering on the road
• Clunking or knocking from the front right lower suspension area
• Uneven tire wear caused by worn control arm bushings or ball joint wear
• Steering instability during braking or cornering
• Suspension play from a damaged or fatigued lower control arm assembly

Installation Notes and Tips

Install this assembly in the front right lower position only on confirmed applications. Verify the ball joint thread diameter, mounting points, and suspension geometry before installation, and inspect adjacent components such as the tie rod ends, strut, and other control arm bushings for wear. Because the part is pre-greased and includes mounting hardware, it is ready for direct replacement once the original assembly is removed.

Quality Assurance

Delphi uses OE-focused engineering and validation for its steering and suspension portfolio. This control arm is evaluated for temperature extremes and extended salt-spray exposure, along with dimensional and material checks to support proper fit and long-term service in the specified Dodge Sprinter 2500 and Sprinter 3500 applications.
