Detailed Product Overview

This control arm and ball joint assembly is engineered for the front right upper suspension position on 2010-2016 Mercedes-Benz E350, 2012-2014 Mercedes-Benz CLS550, 2014 Mercedes-Benz E250, and 2010-2014 Mercedes-Benz E550. The aluminum construction helps keep weight down while the corrosion-resistant finish supports long-term durability in exposed undercar conditions. The assembly arrives pre-greased and includes the bushing, making it a practical replacement for worn upper suspension components. Part number X31CJ0644 also cross-references Dorman Premium CB28167PR for the same application.

Common Problems This Part Addresses

• Front-end clunking or knocking from worn upper control arm joints
• Uneven tire wear caused by looseness in the suspension linkage
• Steering wander or reduced directional stability
• Excess play in the front right upper suspension pivot points
• Noise or vibration from deteriorated bushings or ball joint wear

Installation Notes

Verify the vehicle’s front right upper suspension configuration before ordering. This assembly uses a press-in ball joint and threaded stud type, so proper suspension tools and alignment procedures are required after installation. Confirm the mounting points and compare the original arm shape, length, and width to the replacement part number X31CJ0644 before service.
