Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety during the repair.

2. Remove Driveshaft

Sub-step 1: Loosen and remove the bolts securing the driveshaft to the rear differential and transmission using a socket set.
Sub-step 2: Carefully slide the driveshaft out of the transmission or rear differential, ensuring not to damage any seals.

3. Replace U-joint

Sub-step 1: Position the driveshaft securely in a vise.
Sub-step 2: Use a U-joint press to remove the old U-joint by pressing out the retaining clips and the U-joint itself.
Sub-step 3: Insert the new U-joint into the yoke and press it in place until fully seated. Ensure that the retaining clips are securely installed.

4. Reinstall Driveshaft

Sub-step 1: Align the driveshaft with the transmission and rear differential.
Sub-step 2: Reinstall the bolts and torque them to the manufacturer's specifications. Typical torque values are between 15-25 ft-lbs (check specific vehicle manual).
Sub-step 3: Reconnect the battery.
