Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and the engine is off.
Safety: Use gloves and protective eyewear.

2. Inspect and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission fluid dipstick and check fluid level and condition.
2. If fluid is low or burnt, place a drain pan under the transmission pan.
3. Remove the transmission pan bolts and carefully lower the pan.
4. Replace the filter if applicable.
5. Clean the pan and magnet, and reinstall with a new gasket.
6. Refill the transmission with the manufacturer-recommended fluid.

Sub-steps:
1. Lift the vehicle and secure it on jack stands.
2. Remove the wheel to access the CV joints and axles.
3. Inspect the CV boots for tears or leaks; replace if necessary.
4. If the CV joint or axle shows excessive wear, remove the retaining bolts and disconnect from the transmission.
5. Install the new axle or re-greased CV joint and secure with the retaining bolts to manufacturer torque specifications.

4. Replace Engine Mounts (if necessary)

Sub-steps:
1. Support the engine with a jack and a block of wood.
2. Remove the bolts securing the engine mount to the frame and engine.
3. Replace the mount with a new one, ensuring proper alignment.
