Detailed Description

This Dorman suspension ball joint is precision-engineered and tested for reliable OE-style replacement on the specified vehicles.

What It Helps Fix

• Front suspension looseness or play
• Clunking or knocking from the upper control arm area
• Uneven tire wear caused by worn ball joint movement
• Steering instability during braking or cornering
• Inspection failure from excessive suspension joint wear

Installation Notes and Tips

Verify the vehicle’s year, make, model, and front upper suspension configuration before installation. This part uses a threaded, bolt-in mounting type with a tapered stud, so the existing suspension hardware and mounting points must match the listed application. Confirm fitment carefully on 2009-2012 Chevrolet Colorado and GMC Canyon models with RPO code ZQ8, since that note is specific to the application.

Quality Assurance

Dorman manufactures this ball joint as a premium suspension replacement and subjects it to rigorous testing for fit and function on the listed vehicles. Part number 540-054 is built to replace the original equipment design on the confirmed applications.
