Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and safely supported on jack stands.
Disconnect the 12V battery for safety.

2. Inspect and Replace Drive Axles

Sub-steps:
1. Remove the front or rear wheels, depending on the axle being inspected.
2. Inspect the CV joints for any signs of wear or damage.
3. If damaged, remove the axle nut using a socket set.
4. Detach the axle from the transmission and hub assembly.
5. Install the new axle in reverse order and torque the axle nut to manufacturer specifications (typically around 150 ft-lbs).

3. Check Transmission Fluid

Sub-steps:
1. Remove the transmission fluid fill plug.
2. Check the fluid level; it should be at the bottom of the fill hole.
3. If low, add manufacturer-recommended transmission fluid until it reaches the correct level.
4. If the fluid is discolored or has a burnt smell, consider a fluid change.

4. Motor Mount Inspection and Replacement

Sub-steps:
1. Locate the motor mounts and inspect for cracks or wear.
2. If damaged, remove the mounting bolts using a socket set.
3. Replace with new motor mounts and torque bolts to manufacturer specifications.
