Keep the front suspension tight and your steering precise with the Dorman - OE Solutions Suspension Ball Joint 540-040. This is the front upper ball joint, a direct-fit replacement for the 2019-2023 Ford Ranger. It pivots the connection between the control arm and steering knuckle, letting the suspension travel up and down while the wheel steers.

Key features:

  • Front upper ball joint for the listed Ranger applications.
  • Load-bearing pivot — supports and locates the front wheel while allowing suspension and steering movement.
  • Direct-fit replacement for the listed applications.

A worn ball joint can show up as clunking from the front end over bumps, uneven or accelerated tire wear, and loose or wandering steering. These are signs this part may need replacing; because those symptoms can have other causes, diagnose the front suspension before ordering. If a failed front upper ball joint is the cause, this replaces it. Ball joints wear as a pair, so inspecting and replacing both sides together is good practice for balanced handling.
