Solution

1. Preparation

Tools Required:
- OBD-II scanner
- Socket set
- Floor jack and jack stands
- Torque wrench
- Transmission fluid pump
- Differential fluid
Safety Warnings:
- Ensure the vehicle is securely lifted and supported before working underneath.
- Disconnect the battery before performing any electrical inspections.

2. Inspect and Replace Universal Joints

Lift the Vehicle: Use a floor jack to lift the rear of the vehicle and support it securely with jack stands.
Remove the Drive Shaft:
- Use a socket set to remove the bolts securing the drive shaft to the rear differential.
- Carefully slide the drive shaft out of the transmission.
Inspect Universal Joints:
- Check for any play in the universal joints by attempting to move them; replace if any movement is detected.
Replace Universal Joints if Necessary:
- If worn, use a socket set to remove the old universal joint and install a new one, ensuring proper alignment.

3. Inspect and Change Differential Fluid

Check Differential Fluid Level:
- Remove the filler plug on the differential and check the fluid level.
Drain Old Fluid:
- Place a catch pan under the differential, remove the drain plug, and allow the fluid to fully drain.
Inspect for Contaminants:
- Check the drained fluid for metal shavings or discoloration indicating wear.
Replace with New Fluid:
- Reinstall the drain plug and fill the differential with the manufacturer-recommended fluid using a fluid pump.

4. Inspect Transmission Fluid

Check Fluid Level:
- With the engine running, check the transmission fluid level using the dipstick.
Change Fluid if Contaminated:
- If the fluid appears dark or burnt, drain and replace with new fluid following the manufacturer’s specifications.
Use a Transmission Filter Kit:
- If replacing fluid, consider changing the transmission filter as well.
