Detailed Description

This Mevotech lateral arm, part number CMS861142, is made for the rear left upper suspension location on 2003-2009 Lexus GX470 and 2003-2009 Toyota 4Runner models. The steel tube body provides a rigid replacement structure, while the included natural rubber bushings help restore proper suspension articulation and reduce unwanted movement at the mounting points. The corrosion-resistant black finish adds protection in underbody environments where road splash and debris are common. This part cross-references Dorman OE Solutions 524-573 for the same application.

What It Helps Address

• Rear suspension looseness at the upper lateral arm location
• Clunking or shifting from worn bushings
• Uneven rear wheel alignment caused by worn suspension links
• Excess movement in the rear left upper suspension assembly
• Corrosion-related wear on the original arm

Installation Notes and Tips

Fits 2003-2009 Lexus GX470, rear left upper. Fits 2003-2009 Toyota 4Runner, rear left upper. Confirm the rear left upper position before installation and compare the original arm length and bushing layout to Mevotech CMS861142. Because this arm is not adjustable, final alignment should be checked after installation.
