Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, grease gun, and safety gloves.
Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Lift the Vehicle

Use a jack to lift the rear of the Ford F-150.
Secure the vehicle with jack stands to ensure it is stable before proceeding.

3. Inspect U-Joints

Visually check each U-joint for corrosion, cracks, or rust.
Using your hands, grasp the driveshaft near the U-joint and attempt to move it. It should not have excessive play.

4. Rotate Driveshaft

Carefully rotate the driveshaft by hand while observing the U-joints.
Look for smooth rotation without binding or stiffness. If any resistance is felt, the U-joint may be failing.

5. Grease the U-Joints (if applicable)

If the U-joints are greasable, use a grease gun to apply grease until it oozes out of the seal.
Wipe away any excess grease to prevent dirt accumulation.

6. Reassemble and Lower the Vehicle

After completing the inspection and lubrication, lower the vehicle back to the ground.
Remove the jack stands and ensure all tools are accounted for before driving.
