Detailed Description

This Moog control arm assembly is built for front lower rearward placement and is compatible with select Mercedes-Benz E300, E400, E450, CLS450, GLC300, and GLC350e models. The RK623660 part number is a practical choice when replacing worn suspension components on vehicles such as the Mercedes-Benz GLC300 front lower rearward or Mercedes-Benz E300 front lower rearward. It is also a fitment match for Mercedes-Benz E450 front lower rearward and Mercedes-Benz CLS450 front lower rearward applications.

Moog premium control arms for foreign and domestic nameplates are engineered with attention to structural durability and corrosion resistance. This part cross-references Delphi TC7916 and Dorman - OE Solutions 526-181 for the same application.

What It Helps Address

• Clunking or knocking from the front suspension
• Excessive play at the wheel end of the suspension
• Uneven tire wear related to worn control arm components
• Steering instability or wandering caused by worn bushings or ball joint wear
• Front lower rearward suspension looseness on Mercedes-Benz models

Installation Notes and Tips

Verify front lower rearward position before installation and confirm vehicle-specific fitment by year, make, and model. Inspect adjacent suspension components, alignment angles, and mounting points during replacement. Because this assembly includes the ball joint and bushings, it supports a more complete service replacement than replacing individual wear parts separately.

Quality Assurance

Moog positions this premium control arm assembly for structural strength and corrosion protection, making it a solid service part for suspension repair on Mercedes-Benz E300, GLC300, and related applications. Confirm part number RK623660 against the vehicle’s suspension configuration before ordering.
