Detailed Product Features and Construction

The TC7873 control arm assembly features a robust aluminum control arm constructed through a combination of casting and forging processes, providing strength while reducing weight. The assembly includes black rubber bushings that are pre-greased for immediate use, enhancing durability and reducing maintenance. A chloroprene rubber dust boot protects the machined ball joint from contaminants, extending its service life. The ball joint itself is threaded and comes with a locking nut to ensure secure mounting. This assembly is designed specifically for power steering-equipped vehicles and is not adjustable or greaseable, simplifying installation and maintenance.

Common Suspension Issues Addressed

• Worn or damaged control arm bushings causing steering instability

Installation Notes and Tips

When installing the Delphi TC7873 control arm assembly, ensure the vehicle is securely lifted and supported. Verify the front left upper suspension location before removal. Since the bushings are pre-greased and the ball joint is machined with a threaded stud, no additional lubrication is required. Use the included locking nut to secure the ball joint stud properly. Check alignment after installation to maintain optimal handling and tire wear.
