Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the negative battery terminal to prevent electrical issues.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick or fill plug.
2. Remove the dipstick and check fluid level; add fluid if necessary.
3. If fluid is dirty or burnt, drain the old fluid using a drain pan.
4. Replace with manufacturer-recommended transmission fluid, ensuring the appropriate level is achieved.

3. Check and Replace Differential Fluid

Sub-steps:
1. Remove the differential fill plug.
2. Check fluid level; if low, drain the old fluid using a drain pan.
3. Replace with manufacturer-recommended differential fluid, ensuring it is filled to the proper level.

4. Inspect and Replace Driveshaft and Universal Joints

Sub-steps:
1. Raise the vehicle securely on jack stands.
2. Inspect the driveshaft for any signs of damage or wear.
3. Check universal joints for play; replace if any movement is detected.
4. If replacing, remove the driveshaft by unbolting it at the transmission and differential.
5. Install the new driveshaft or universal joints, torque bolts to the manufacturer’s specifications.

5. Inspect and Replace CV Joints

Sub-steps:
1. Raise the vehicle and remove the wheel to access the CV joint.
2. Inspect the CV boot for tears; replace if necessary.
3. If the CV joint is damaged, remove the axle by unbolting it from the hub and differential.
4. Install a new CV axle, ensuring all bolts are torqued correctly.

6. Inspect and Replace Engine/Transmission Mounts

Sub-steps:
1. Visually inspect mounts for cracks or excessive wear.
2. If damaged, support the engine and transmission using a jack.
3. Unbolt the damaged mounts and replace with new ones.
4. Torque all bolts to the specified values.
