Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, grease gun, U-joint puller or press.
Ensure the vehicle is on a flat surface, and engage the parking brake.
Disconnect the battery for safety.

2. Raise Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Ensure the vehicle is stable and secure before working underneath.

3. Remove Driveshaft

Tools Required: Socket set, torque wrench.
Remove the bolts attaching the driveshaft to the differential and transmission.
Carefully slide the driveshaft out of the U-joint connection.

4. Inspect and Replace U-joints

Check the U-joint for excessive play or signs of wear.
If replacement is necessary:
1. Use a U-joint puller or press to remove the old U-joint from the driveshaft.
2. Clean the driveshaft ends where the U-joint sits.
3. Insert the new U-joint into the driveshaft, ensuring it is seated correctly.
4. Use a press to secure the U-joint in place if necessary.

5. Reinstall Driveshaft

Reconnect the driveshaft to the differential and transmission.
Torque the bolts to the manufacturer’s specifications (usually around 30-40 ft-lbs, but verify with the service manual).

6. Lubrication

Use a grease gun to lubricate the new U-joint if applicable.
Ensure the grease is visible at the U-joint seals.

7. Lower Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.
