Overview
The 4 Wheel Parts Factory Bronco tubular front upper control arm, part number 4WP52005B, is for the 2021 and 2022 Ford Bronco.
The arm uses a High Angle Ball Joint, which 4 Wheel Parts says gives the strength of a race-style uniball arm with the ride quality and characteristics of the factory part.
It has PTMEG bushings and helix grooved pivot points with a sealed dust cap. These parts are designed for quiet, low-maintenance use over time.
The arm is designed to correct alignment after a lift. Its High Angle Ball Joint aims to give the strength of a race-style uniball arm with ride quality close to the factory part. Joint, bushing and pivot details are shown below for comparison with the arm being replaced.

Signs of a worn upper arm
Upper control arms locate the axle and help keep the wheel moving in a controlled path. When a joint or bushing wears, the wheel can wander, the steering can feel loose, and the tire can wear unevenly on its inner or outer edge. Wear is often gradual, so comparing the arms side to side is a useful check.
Replacement is often paired with alignment work, because a new arm changes the angles that the alignment sets. Look at the frame-side mounts and the joint boot while the arm is out, and check nearby links for wear at the same time.
- Look for play at the joint by hand
- Check bushings for cracks or separation
- Inspect the dust cap for tears
- Check tire wear patterns after the next alignment
