Detailed Description

This Dorman suspension control arm and ball joint assembly is engineered as a direct OE replacement for the front left lower suspension on Buick Encore and Chevrolet Trax models. The assembly combines a boxed steel control arm with an installed ball joint and bushings to restore suspension geometry and support predictable steering response. Dorman 527-959 is a practical replacement choice when servicing worn front suspension components on 2013-2022 Buick Encore and 2013-2022 Chevrolet Trax vehicles.

The part is pre-greased, does not use a grease fitting, and is built with a regular-grade, light-duty suspension specification. Its bolt-on attachment and bolt-in ball joint mounting simplify replacement of the original front left lower arm while maintaining the intended OE-style fit and function. This part cross-references MOOG Chassis Products RK623137 for the same application.

What It Helps Address

• Clunking or knocking from a worn front lower control arm
• Loose or inconsistent steering feel
• Uneven tire wear caused by suspension wear
• Directional instability during braking or cornering
• Ball joint or bushing wear in the front left lower suspension

Installation Notes and Tips

Install on the front left lower position only. Verify vehicle year, make, and model before ordering, especially on Buick Encore and Chevrolet Trax applications. Because the ball joint is already installed and the assembly is pre-greased, the part is ready for suspension service, but alignment should be checked after installation to confirm proper suspension geometry.

Quality Assurance

Dorman uses an industry-leading evaluation process for this replacement assembly to support smooth ride quality, directional stability, and predictable handling characteristics. The design follows the original equipment layout for the listed Buick Encore and Chevrolet Trax applications.
