Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lift it using a jack and jack stands.
Disconnect the 12V battery to ensure safety.

2. Inspect and Tighten Suspension Components

Tools Required: Socket set, torque wrench
Inspect control arms, bushings, and strut mounts for wear.
Use a torque wrench to ensure all bolts are tightened to manufacturer specifications.
If any components are damaged, proceed to replace them.

3. Examine and Replace Drive Axles (if necessary)

Tools Required: Socket set, pry bar, axle puller
Remove the wheel and brake assembly to gain access to the drive axle.
Inspect the drive axle for any signs of wear or damage (cracks, tears in the CV boot).
If defective, use an axle puller to remove the old axle and replace it with a new one.
Reassemble the wheel and brake assembly, ensuring all bolts are torqued properly.

4. Test Electric Motor Mounts

Tools Required: Socket set, pry bar
Locate the electric motor mounts and inspect for cracks or deterioration.
If needed, remove the motor mounts from the chassis using a socket set.
Replace with new mounts and reattach securely.
