Keep the front suspension of your 1986-1989 Toyota 4Runner or 1986-1989 Toyota Pickup pivoting smoothly and securely with the Dorman OE Solutions front lower ball joint, part number 539-933. This suspension ball joint is precision-engineered and rigorously tested as a direct replacement, designed to fit and perform like the original equipment on these vehicles.
A ball joint is the pivot that connects the steering knuckle to the control arm. It lets the wheel move up and down with the suspension while it turns with the steering. Dorman built this unit around the design and dimensions of the factory component.
- Direct replacement: fits and performs like the original equipment on the listed applications.
- Reliable fit: precision-engineered to match the design and dimensions of the original components.
- Durable construction: made to strict standards from steel and rubber material.

A worn ball joint can show up as clunking over bumps, loose or wandering steering, uneven tire wear, or play at the wheel. Other steering and suspension parts can cause the same symptoms, so have the front end inspected first. If a worn front lower ball joint is the cause, this part replaces it. See the "Vehicles it fits" section for engine-specific details.
