Detailed Description

This Dorman suspension ball joint, part number 538-393, is designed for direct replacement use on specific Chevrolet front lower suspension applications. The steel body, threaded mounting type, and pinch-style stud support a secure OE-style service fit, while the included rubber dust boot helps protect the joint from road debris and moisture. It is a standard replacement component for Chevrolet Chevy models from 1994-2012 and for the 2003 Chevrolet Chevy Monza, both in the front lower position.

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

What It Helps Address

• Front suspension looseness or play at the ball joint
• Clunking or knocking from the lower front suspension

Installation Notes and Tips

Confirm stud thread length, wrench size, and fitment against the original part before service. Professional installation and a post-repair alignment are recommended after suspension work.
