Solution

1. Preparation

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

2. Raise the Vehicle

Use a jack to lift the vehicle.
Secure the vehicle on jack stands for safety.

3. Inspect U-joints

Visually inspect each U-joint for visible damage or rust.
Grasp the U-joint and attempt to move it; any excessive movement indicates wear.
Spin the driveshaft by hand and listen for any unusual noises.

4. Lubricate U-joints (if applicable)

If U-joints are equipped with grease fittings, use a grease gun to apply the appropriate grease.
Ensure that grease is flowing from the U-joint seal, indicating it is full.
