Solution

1. Preparation

Tools Needed: OBD-II scanner, torque wrench, jack and jack stands, wheel chocks, multimeter (if needed)
Safety Warning: Disconnect the battery before working on any electrical components, and allow the vehicle to cool down before inspections.

2. Inspect and Replace Motor Mounts

Lift the Vehicle: Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove Underbody Shield: Detach any underbody shields to access the motor mounts.
Locate Motor Mounts: Identify the motor mounts connected to the electric motor.
Inspect Mounts: Check for cracks, tears, or excessive wear. If damaged, proceed to replace them.
Remove Old Motor Mounts: Use a socket set to unbolt the old motor mounts from the frame and motor.
Install New Motor Mounts: Position the new motor mounts and torque the bolts to the manufacturer’s specifications (refer to service manual for torque values).

3. Check and Repair Suspension Components

Inspect Suspension: Check all suspension components for play, cracks, or wear.
Replace Worn Parts: If any components are damaged (e.g., bushings, struts), replace them with OEM parts.
Reassemble: Once repairs are made, reassemble any disassembled parts.

4. Balance and Align Wheels

Remove Wheels: Use a socket set to take off the wheels.
Balance Wheels: Use a wheel balancer to ensure each wheel is properly balanced.
Check Alignment: Use alignment tools or visit a professional for wheel alignment.
Reinstall Wheels: Put the wheels back on and torque the lug nuts to the specified value.
