Ensure the vehicle is parked on a flat surface and securely raise the vehicle using jack stands.
Disconnect the negative battery terminal.

2. Inspect Driveshaft

Remove any protective covers if applicable.
Check the driveshaft for any visible dents, cracks, or bends.
Use a dial indicator to measure any runout on the driveshaft.

3. Examine and Replace U-Joints

Tools Required: U-joint puller, socket set, grease gun
Remove the driveshaft from the vehicle by loosening the bolts at both ends.
Inspect the U-joints for any signs of wear or play.
If worn, use the U-joint puller to remove and replace the U-joints with new ones.
Apply grease to the new U-joints as per manufacturer specifications.

4. Align Driveshaft

Reinstall the driveshaft ensuring it is properly aligned.
Check the alignment of the driveshaft with the differential and transmission.
Torque the bolts to the manufacturer’s specifications (typically 15-20 ft-lbs).
