Built for OE Performance

The Mevotech GS86508 ball joint is engineered to restore factory-style steering response, suspension articulation, and ride quality. As an OE replacement for Lexus front left lower suspension service, it supports precise fitment on vehicles such as the Lexus IS250, IS350, GS300, GS450h, RC300, and IS F. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. The Mevotech GS86508 is a practical choice when replacing a worn front left lower ball joint on Lexus IS350 and related rear-wheel-drive platforms.

What It Helps Fix

• Front-end clunking or looseness from a worn ball joint
• Uneven steering feel or wandering at the wheel
• Suspension play that can affect alignment stability
• Noise over bumps caused by joint wear
• Loss of original ride control at the front left lower corner

Installation Notes

Verify the front left lower position and confirm the stud thread size and mounting style before installation. The bolt-in design and included mounting hardware help streamline replacement, and the pre-greased joint is ready for service. Always inspect adjacent suspension components and perform a wheel alignment after installation. For Lexus GS350, IS300, and RC350 applications, confirm the vehicle’s exact year and trim against the fitment list before ordering. Part number GS86508 should be matched to the vehicle’s original suspension configuration.

Quality Assurance

Mevotech Original Grade parts are built to match the original manufacturer’s fit, form, and function for everyday driving. GS86508 is designed to restore OE performance characteristics in supported Lexus applications while using service-ready components such as the dust boot, cotter pin, and castle nut where required.
