2. Carefully slide the driveshaft out of the transmission or differential, ensuring to note the orientation for reinstallation.

3. Replace U-Joints

Sub-steps:
1. Secure the driveshaft in a vice.
2. Use a U-joint puller to remove the old U-joints by pressing out the cross and bearing cups.
3. Clean the U-joint yoke areas to remove any debris or rust.
4. Insert the new U-joint into the yoke, ensuring proper alignment.
5. Press in the new bearing cups until they are fully seated.

4. Reinstall Driveshaft

Sub-steps:
1. Align the driveshaft in the original orientation and slide it back into the transmission or differential.
2. Secure the driveshaft with the previously removed bolts, tightening to the manufacturer's specified torque values.

5. Lubrication

Sub-steps:
1. Use a grease gun to apply grease to the U-joint grease fittings until fresh grease appears at the seals.
2. Ensure all joints are adequately lubricated to prevent premature wear.
