Detailed Description

Steering wander or imprecise road feel

Excess movement in the lower control arm connection

Installation Notes and Tips

This part uses a press-in mounting type and is intended for front lower positions only. Verify the vehicle application, model year, and standard-size fitment before installation. The included dust boot, castle nut, and mounting hardware support a complete service setup, while the cotter pin hole allows secure fastening where required. Because the joint is not greaseable and does not include a grease fitting, it is designed as a sealed service part.

Dorman manufactures this ball joint as a precision-engineered replacement and subjects it to rigorous testing for fit and function on listed applications. Part number 540-037 is built to meet the demands of front suspension service on Ford Ranger, Ford Explorer, Mazda B3000, and related vehicles.
