Detailed Description

This lateral arm and ball joint assembly is built from steel with casting/forged control arm construction and includes steel and rubber bushings for the rear lower forward suspension position. The ball joint is already installed, pre-greased, and uses a tapered stud, making it a practical replacement when servicing worn rear suspension components on the Lexus CT200h, Scion tC, and Toyota Corolla iM. Dorman 526-899 is a direct-fit replacement for specific vehicles where OE-style suspension alignment and joint movement are required.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Repair Uses

• Clunking or knocking from the rear suspension
• Excessive play in the rear lower forward arm assembly
• Uneven tire wear related to worn suspension geometry
• Loose or unstable rear-end handling over bumps
• Ball joint wear at the rear lower forward position

Installation Notes and Tips

Install at the rear lower forward suspension location using the bolt-on attachment points. Because the ball joint is already installed and the assembly is pre-greased, replacement can be completed without transferring the joint from the arm. After installation, verify alignment and inspect adjacent bushings and fasteners for wear.

Quality Assurance

Dorman states this assembly is precision-engineered and rigorously tested to provide reliable replacement performance for the original equipment part on the listed vehicles.
