Solution

1. Preparation

Gather Tools: Ensure you have a socket set, torque wrench, pry bar, and a U-joint removal tool or hammer.
Safety Measures: Secure the vehicle on jack stands and ensure it is stable before working underneath.

2. Remove Driveshaft

Disconnect Battery: Disconnect the negative battery terminal to avoid any electrical issues.
Mark Driveshaft Position: Use a marker to make reference marks on the driveshaft and differential for reassembly alignment.
Remove Bolts: Use a socket set to remove the bolts securing the driveshaft to the differential and U-joint.
Gently Pry Off Driveshaft: Carefully pry the driveshaft from the U-joint using a pry bar, taking care not to damage any surrounding components.

3. Inspect and Replace U-joint

Check U-joint: Inspect the U-joint for any signs of wear or play. If excessive play is found, proceed to replace the U-joint.
Remove Old U-joint: Use a U-joint removal tool to press the U-joint out of the driveshaft yoke.
Install New U-joint:
- Apply grease to the new U-joint.
- Position the new U-joint into the yoke and press it in using the U-joint tool.
- Ensure it is seated properly and that the caps are secure.
Reassemble Driveshaft: Reattach the driveshaft to the differential, aligning it with the reference marks made earlier, and torque the bolts to manufacturer specifications.
