Detailed Description

Mevotech Original Grade GS861136 is engineered as a premium OE replacement for the front left upper position. It matches the original manufacturer’s fit, form, and function to help return Lexus IS250, IS350, IS F, IS200t, and IS300 models to factory-like handling and ride characteristics. This part cross-references MOOG Chassis Products RK622662 for the same application.

The assembly uses a steel arm with rubber bushings and a rubber dust boot to support consistent suspension movement and reduce unwanted noise and vibration. The pre-greased ball joint, threaded stud, and included service hardware help streamline replacement work on the front suspension.

Common Problems This Part Can Address

• Front-end clunking or popping from a worn upper control arm joint
• Loose or imprecise steering feel
• Uneven tire wear caused by suspension wear
• Excessive play in the front left upper suspension point
• Restoring factory ride height and alignment stability after wear

Installation Notes and Tips

Install GS861136 at the front left upper suspension position only. After replacement, perform a professional wheel alignment to verify camber and suspension geometry. Inspect adjacent bushings, ball joints, and steering components during service to confirm the rest of the front suspension is in good condition.
