Disconnect the battery pack to ensure safety while working on electrical components.

2. Inspect and Replace Motor Mounts

Sub-steps:
1. Remove any covers or shields obstructing access to the motor mounts.
2. Using a socket set, remove the bolts securing the motor mounts to the vehicle.
3. Carefully lift the motor slightly to relieve pressure on the mounts.
4. Inspect the mounts for cracks, tears, or excessive wear.
5. If damaged, replace with OEM motor mounts, ensuring proper alignment.
6. Torque the bolts to the manufacturer's specifications (consult repair manual for exact torque values).

3. Check and Tighten Battery Connections

Sub-steps:
1. Access the battery pack terminals by removing any protective covers.
2. Inspect the terminals for corrosion or loose connections.
3. Clean any corrosion using a solution of baking soda and water, then rinse and dry.
4. Tighten the terminal connections to the specified torque.

4. Inspect Suspension Components

Sub-steps:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Visually inspect all suspension components including struts, shocks, and control arms.
3. Check for signs of wear such as cracks, leaks, or broken parts.
