Detailed Description

This Dorman lateral arm, part number 523-052, is made for rear left lower forward and rear right lower forward positions on select Buick suspension systems. It is a direct replacement style component for 2005-2007 Buick Allure and Buick LaCrosse models, and for 2008-2009 Buick Allure and Buick LaCrosse models without RPO code FE4 special ride and handling suspension. The steel tubular construction and included rubber bushings are specified to match the original suspension layout for these applications. This part cross-references MOOG Chassis Products RK660275 for the same application.

What This Part Helps Address

• Rear suspension looseness from a worn lateral arm
• Clunking or knocking from deteriorated bushings
• Uneven rear wheel tracking caused by suspension wear
• Excess movement in the rear lower forward suspension link
• Restoring proper rear suspension geometry on Buick Allure and Buick LaCrosse models

Installation Notes and Tips

Verify the vehicle’s rear position before ordering: this part is for rear left lower forward and rear right lower forward locations only. Confirm the vehicle does not use RPO code FE4 on 2008-2009 applications. Inspect adjacent suspension bushings and mounting points during replacement, and align the vehicle after installation to confirm rear suspension geometry is set correctly.
