Detailed Description

This Dorman suspension ball joint is engineered as an OE-style replacement for front upper suspension service on 1999-2006 Chevrolet Silverado 1500, 1999-2006 GMC Sierra 1500, 2000-2006 Chevrolet Suburban 1500, 2001-2006 Chevrolet Tahoe, 2000-2006 GMC Yukon, and other listed GM platforms.

What It Helps Address

• Front-end looseness or play from a worn upper ball joint
• Clunking or popping noises over bumps and turns
• Uneven tire wear related to suspension joint wear
• Steering wander caused by excess suspension movement
• Inspection failure from damaged or worn ball joint components

Installation Notes and Tips

Compatible With front upper positions only on the listed vehicles, including 2003-2014 Chevrolet Express 1500, 2003-2014 GMC Savana 1500, 2002-2006 Cadillac Escalade, 2002-2006 Chevrolet Avalanche 1500, and 2007 Chevrolet Silverado 1500 Classic. Verify year, model, and front upper application before installation. The press-in design requires proper suspension service tools and correct alignment of the tapered stud and castle nut during assembly. The part includes a cotter pin hole, but no grease fitting, so it is not a greaseable service joint.

Dorman states this ball joint is precision-engineered and rigorously tested for reliable replacement performance on specific vehicles. Part number 540-063 is built to match the original equipment application requirements for the listed GM trucks and SUVs.
