Detailed Description

This Dorman lateral arm, part number 527-183, is engineered and tested to replace the original equipment arm on specific vehicles. It is designed for the rear left upper forward position on 2016-2025 Chevrolet Malibu and 2018-2020 Buick Regal Sportback models. The steel body, rubber bushings, and stamped construction support a direct replacement approach for suspension repair work where the original arm has worn, bent, or developed bushing play. This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application.

What It Is Used For

• Replacing a worn rear suspension lateral arm
• Correcting looseness or clunking from worn bushings
• Restoring rear wheel suspension geometry after arm wear
• Addressing noise from cracked or deteriorated rubber bushings
• Repairing a bent or damaged rear left upper forward arm

Installation Notes and Tips

Verify the rear left upper forward position before installation and confirm vehicle year, make, and model against the listed fitment. The bolt-on design simplifies replacement, but the mounting hardware is not included, so reuse or source the correct fasteners as needed. Because this arm is not adjustable, final alignment should be checked after installation on the vehicle.

Quality Assurance

Dorman manufactures this lateral arm as a standard replacement part and subjects it to engineering review and testing to support reliable OE-style service on the listed Chevrolet Malibu and Buick Regal Sportback applications.
