Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Inspect Drive Units

Remove the underbody shield (if applicable) using a socket set.
Inspect the drive units visually for any signs of leakage or damage.
Check all electrical connections and harness for integrity and secure fit.

3. Check Wheel Alignment and Tire Condition

Use a wheel alignment tool to check the alignment settings against manufacturer specifications.
Rotate tires to ensure even wear is accounted for and check for any visible defects.

4. Inspect Motor Mounts

Locate the motor mounts and visually inspect them for cracking or excessive wear.
If any damage is found, proceed to replace the motor mounts.
- Sub-steps:
  - Remove the bolts securing the motor mounts.
  - Lift the motor slightly to relieve tension on the mounts.
  - Replace with new mounts and torque to manufacturer specifications.
