Detailed Description

This Dorman suspension ball joint, part number 540-051, is engineered for front lower suspension locations on a wide range of heavy-duty GM platforms, including Chevrolet Silverado 2500, Silverado 3500, GMC Sierra 2500, Sierra 3500, and Hummer H2.

Built from steel with a threaded body and press-in mounting style, this ball joint is made to restore proper steering and suspension connection at the lower control arm. The included dust boot helps protect the joint from road debris and moisture, while the greaseable design supports routine service maintenance.

Compatible With 1999-2013 Chevrolet Silverado, 1999-2013 GMC Sierra, and 2003-2009 Hummer H2 front lower applications, this Dorman 540-051 replacement is suited for drivers addressing wear in the front suspension of work trucks and heavy-duty SUVs.

What It Helps Solve

• Front-end looseness or play from a worn lower ball joint
• Clunking or popping noises over bumps and turns
• Uneven tire wear caused by suspension joint wear
• Steering instability or wandering at the front axle
• Failed dust boot protection that exposes the joint to contamination

Installation Notes and Tips

Verify vehicle fitment by year, make, model, and front lower position before installation. Because this is a press-in ball joint, proper removal and installation tools are recommended to avoid damage to the control arm. Confirm the tapered stud, castle nut, and cotter pin hole alignment during assembly, and follow the vehicle service procedure for torque specifications.

Quality Assurance

Dorman manufactures this ball joint as a precision-engineered replacement part and subjects it to rigorous testing to support dependable OE-style service on the listed applications.
