How to remove and install a upper control arm on Ford F-150?

The manufacturer advises discarding removed suspension component fasteners (nuts and bolts) and replacing them with new ones. To begin, loosen the wheel lug nuts and raise the front of the vehicle, supporting it securely on jackstands. Apply the parking brake and remove the wheel. Next, remove the wheel speed sensor from the steering knuckle. Then, remove the shock absorber/coil spring. Loosen the upper balljoint nut and use a balljoint separator or puller to separate the balljoint from the steering knuckle. Take caution not to allow the steering knuckle to fall outward, as it may damage the brake hose. It is recommended to wire the steering knuckle to the coil spring to prevent this. Proceed to remove the fasteners and detach the upper control arm from the frame. Inspect the bushings for wear and deterioration, and if necessary, have new bushings installed at an automotive machine shop. Installation is the reverse of removal, ensuring all suspension fasteners are tightened. It is advisable to have the wheel alignment checked and adjusted if needed.

Detach the stabilizer link from the lower control arm. Remove the lower shock absorber/coil spring fasteners.

Q: How to remove and install a upper control arm on Ford F-150?
A: The manufacturer advises discarding removed suspension component fasteners (nuts and bolts) and replacing them with new ones. To begin, loosen the wheel lug nuts and raise the front of the vehicle, supporting it securely on jackstands. Apply the parking brake and remove the wheel. Next, remove the wheel speed sensor from the Steering Knuckle. Then, remove the Shock Absorber/coil spring. Loosen the upper balljoint nut and use a balljoint separator or puller to separate the balljoint from the steering knuckle. Take caution not to allow the steering knuckle to fall outward, as it may damage the brake hose. It is recommended to wire the steering knuckle to the coil spring to prevent this. Proceed to remove the fasteners and detach the upper control arm from the frame. Inspect the bushings for wear and deterioration, and if necessary, have new bushings installed at an automotive machine shop. Installation is the reverse of removal, ensuring all suspension fasteners are tightened. It is advisable to have the wheel alignment checked and adjusted if needed.
