Solution

1. Preparation

Ensure the vehicle is on a level surface and securely supported with jack stands.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, socket set, funnel.
Steps:
1. Locate the transmission fluid dipstick or fill plug.
2. Remove the dipstick or fill plug and check fluid level.
3. If low, use a transmission fluid pump to add the specified type of ATF (consult owner’s manual).
4. Inspect the fluid for burnt smell or metal particles; if found, consider a complete fluid change.

3. Inspect and Replace Drive Axles (if necessary)

Tools Required: Socket set, pry bar, torque wrench.
Steps:
1. Remove the wheel and brake assembly to access the drive axle.
2. Inspect the CV boots for tears or leaks; replace if damaged.
3. Remove the axle nut and the retaining bolts for the axle.
4. Pull out the drive axle from the transmission and install the new axle.
5. Reassemble in reverse order and torque all bolts to the manufacturer’s specification.

4. Inspect and Replace Transmission Mounts (if necessary)

Tools Required: Socket set, pry bar, torque wrench.
Steps:
1. Locate the transmission mounts underneath the vehicle.
2. Inspect for cracks or excessive wear.
3. If damaged, unbolt the old mounts and replace with new ones.
4. Re-torque to manufacturer specifications and ensure proper alignment.
