Product Details

This suspension control arm is precision-engineered and tested to replace the original equipment part on specific vehicles. The Dorman 528-091 uses a steel body with casting/forged construction, black powder coating, and rubber bushings to match the service requirements of the front left lower suspension position. It is not pre-greased, does not include a grease fitting, and does not include a ball joint or mounting hardware. This part cross-references MOOG Chassis Products RK643680 for the same application.

Common Repair Uses

• Restoring front suspension geometry after worn arm bushings
• Replacing a bent or damaged lower control arm
• Addressing clunking or looseness from suspension wear
• Correcting uneven tire wear related to front-end component play
• Replacing a failed OE-style arm on Lexus IS250, IS350, IS300, GS350, or GS300 models

Installation Notes

Verify the front left lower position before installation and confirm vehicle year, model, and suspension configuration against the fitment list. Because the ball joint is not included and the mounting type is press-in, inspect related suspension components and service the joint as required during installation. Final alignment is recommended after replacement of any control arm.
