Solution

1. Preparation

Gather tools and parts needed for the replacement.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the vehicle.

2. Raise the Vehicle

Use a jack to lift the vehicle safely and secure it with jack stands.
Make sure the vehicle is stable before proceeding to the next steps.

3. Remove Driveshaft

Tools Required: Socket set, torque wrench
Remove any protective covers if applicable.
Unbolt the U-joint from the driveshaft using the appropriate socket size.
Carefully slide the driveshaft out of the U-joint connection to access the U-joint itself.

4. Replace U-joint

Tools Required: U-joint puller, grease gun
Use a U-joint puller to remove the old U-joint from the yoke.
Clean the yoke and inspect for any damage before installation.
Apply grease to the new U-joint's needle bearings.
Install the new U-joint into the yoke and secure it with the retaining clips.
Make sure to align it correctly with the driveshaft.

5. Reinstall Driveshaft

Reattach the driveshaft to the U-joint and secure it with bolts, using a torque wrench to achieve manufacturer specifications.
Replace any protective covers that were removed.

6. Lower the Vehicle

Remove the jack stands and safely lower the vehicle back to the ground.
Reconnect the battery and ensure all tools are accounted for.
