Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery for safety.

2. Raise the Vehicle

Tools Required: Floor jack, jack stands.
Lift the vehicle using a floor jack and secure it with jack stands.
Safety Warning: Ensure the vehicle is stable before working underneath.

3. Remove the Drive Shaft

Tools Required: Socket set, torque wrench.
Unbolt the drive shaft from the rear differential and the transmission using the appropriate socket.
Carefully slide the drive shaft out of the U-joint connections.

4. Inspect and Replace U-joint

Tools Required: U-joint puller, hammer, bench vise.
Remove the U-joint from the drive shaft using a U-joint puller or a hammer and socket for leverage.
Check the replacement U-joint for compatibility with the vehicle specifications.
Install the new U-joint by pressing it into place using the bench vise, ensuring it is seated properly.

5. Reassemble the Drive Shaft

Reinstall the drive shaft back into the U-joint connections at the transmission and rear differential.
Torque the bolts to the manufacturer’s specifications (typically 30-40 ft-lbs, but refer to the service manual for exact values).

6. Lower the Vehicle
