Solution

1. Preparation

Tools Required: Jack stands, socket set, torque wrench, U-joint puller, grease gun, safety glasses, gloves
Safety Warnings: Ensure the vehicle is securely supported on jack stands before working underneath.

2. Remove Driveshaft

Loosen Bolts: Use the socket set to loosen and remove the bolts securing the driveshaft to the differential and transmission.
Mark Alignment: Mark the position of the driveshaft relative to the U-joints to ensure proper reinstallation.
Remove Driveshaft: Carefully slide the driveshaft out of the U-joint and set it aside.

3. Replace U-joints

Remove Old U-joint: Use a U-joint puller to press out the old U-joint from the driveshaft, ensuring to remove all caps.
Install New U-joint: Position the new U-joint in place and use the U-joint puller to press it in securely.
Reinstall Caps: Ensure that the caps on the new U-joint are properly seated and secured.

4. Reinstall Driveshaft

Align Driveshaft: Align the driveshaft with the marks made earlier and slide it back into position.
Tighten Bolts: Securely tighten the bolts using a torque wrench to the manufacturer’s specified torque settings.
Check Grease: If applicable, lubricate the U-joint with a grease gun until grease flows from the fittings.
