Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Inspect and Change Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Check the fluid level and condition (should be bright red and not burnt).
3. If fluid is low or contaminated, drain the old fluid using a drain pan.
4. Replace the transmission filter if applicable.
5. Refill with the manufacturer-recommended transmission fluid type.

3. Inspect and Replace CV Joints/Axles

Sub-steps:
1. Safely raise the vehicle using jack stands and remove the front wheels.
2. Inspect the CV boots for tears or leaks. If damaged, replace the CV joint.
3. Remove the axle nut using a socket and breaker bar.
4. Detach the CV axle from the transmission and wheel hub.
5. Install the new CV axle and secure it with the axle nut to the specified torque (typically 150 lb-ft).
6. Reinstall the wheels and lower the vehicle.

4. Check Engine and Transmission Mounts

Sub-steps:
1. Inspect the mounts visually for cracks or wear.
2. If necessary, remove the engine mount bolts and lift the engine slightly using a jack.
3. Replace any worn or damaged mounts and secure them to the specified torque.
