Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface, set the parking brake, and disconnect the battery.
Tools required: Socket set, torque wrench, U-joint puller or press, grease gun.

2. Remove Driveshaft

Sub-steps:
1. Loosen and remove the bolts securing the driveshaft to the rear axle and transmission using the socket set.
2. Carefully slide the driveshaft out of the transmission and rear differential. Take care not to damage the seals.

3. Remove U-joint

Sub-steps:
1. Place the driveshaft on a workbench.
2. Use the U-joint puller or press to remove the U-joint by pressing out the caps.
3. Clean the U-joint area and inspect for any debris or old grease.

4. Install New U-joint

Sub-steps:
1. Apply grease to the new U-joint before installation.
2. Position the new U-joint in the driveshaft yoke and press the caps back in using the U-joint press.
3. Ensure that the U-joint can rotate freely and has no binding.

5. Reinstall Driveshaft

Sub-steps:
1. Align the driveshaft with the transmission and rear axle, sliding it back into place.
2. Reinstall the bolts and torque to the manufacturer’s specifications (typically around 15-20 lb-ft).

6. Final Check and Cleanup

Sub-steps:
1. Reconnect the battery.
2. Lower the vehicle and perform a final visual inspection of the installed components.
3. Test drive the vehicle to ensure the issue is resolved.
