Detailed Description

This Dorman lateral arm is engineered for direct replacement use on select Mercedes-Benz GL and GLE platform vehicles. The design follows OE-style dimensions and mounting points, with a 388 mm length, steel bushing material, and a tubular arm profile to match the original suspension layout. If you are servicing a Mercedes-Benz GLE350 rear upper forward lateral arm or replacing a worn Mercedes-Benz GL550 rear upper forward suspension arm, part number 520-062 provides a focused replacement option.

Use this component on 2012-2019 Mercedes-Benz ML, GL, GLE, and GLS models listed in the fitment data, including GLE350, GLE400, GLE63 AMG, GLS550, GL450, and ML350 applications. The Dorman 520-062 lateral arm is built for the rear upper forward location, where bushing wear and arm movement can affect suspension alignment and ride quality.

What It Helps Address

• Rear suspension looseness from worn bushings
• Clunking or knocking from the rear upper control area
• Uneven rear tire wear related to suspension geometry
• Excessive movement in the rear upper forward arm
• Restoring OE-style rear suspension alignment on Mercedes-Benz GL, GLE, and GLS models

Installation Notes and Tips

Install in the rear upper forward suspension position only. Verify mounting hole diameter, arm length, and bushing orientation before installation. Because this is a bolt-on lateral arm with no mounting hardware included, reuse or source the correct fasteners as required by the vehicle service procedure. A final alignment is recommended after suspension component replacement.

Quality Assurance

Dorman designs this part as a standard replacement and subjects it to engineering and testing checks for fit and function on the listed vehicles. The part number is 520-062.
