Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and securely lifted using jack stands.
Wear safety glasses and gloves while working.

2. Inspect and Replace U-Joints

Tools Required: Socket set, U-joint puller, grease gun
Remove the drive shaft from the vehicle by unbolting it from the differential and transmission.
Using a U-joint puller, remove the old U-joints from the drive shaft.
Clean the U-joint cups and apply grease to the new U-joints before installing them.
Install the new U-joints and reassemble the drive shaft, ensuring it is properly aligned and secured with the appropriate torque (usually around 15-20 lb-ft).

3. Balance the Drive Shaft

Remove any balance weights that are damaged or missing.
If necessary, take the drive shaft to a professional shop for dynamic balancing.
Reinstall the drive shaft once balanced correctly.

4. Inspect Rear Differential

Remove the fill plug on the rear differential and check the fluid level.
If fluid is low, top it off with the recommended gear oil (typically 75W-90).
Check for any signs of metal shavings or debris in the fluid, indicating potential internal damage.

5. Reassemble and Test

Reinstall any components removed during the diagnostic process.
Lower the vehicle and perform a test drive to ensure the vibration issue is resolved.
