Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely elevated with jack stands.
Disconnect the battery to prevent any electrical issues while working.

2. Remove Driveshaft

Sub-step 1: Mark the position of the driveshaft on both the rear differential and the transmission for reinstallation alignment.
Sub-step 2: Use a wrench to remove the bolts securing the U-joint to the driveshaft and differential.
Sub-step 3: Carefully slide the driveshaft out of the transmission, ensuring no damage to the surrounding components.

3. Inspect and Replace U-joint

Sub-step 1: Use a U-joint puller tool to remove the old U-joint from the driveshaft.
Sub-step 2: Clean the U-joint yoke and inspect for any damage; replace if necessary.
Sub-step 3: Apply grease to the new U-joint and install it into the yoke, ensuring it is seated correctly.
Sub-step 4: Reinstall the driveshaft, aligning it with the marks made during removal and securing it with bolts to the specified torque (typically 15-20 ft-lbs, check service manual).

4. Reconnect Battery and Test

Sub-step 1: Reconnect the battery and lower the vehicle.
Sub-step 2: Start the engine and take the vehicle for a test drive to ensure that vibrations and noises have been resolved.
