Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the 12V battery for safety prior to any electrical work.

2. Inspect and Replace Motor Mounts

Tools Required: Socket set, torque wrench, jack stands, and a pry bar.
Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Remove the undercarriage cover if applicable.
3. Locate the motor mounts and inspect for any cracks or excessive wear.
4. If damaged, remove the bolts securing the motor mounts using the socket set.
5. Replace with new motor mounts and torque the bolts to the manufacturer's specifications (Refer to the service manual for torque values).

3. Inspect Suspension Components

Tools Required: Wrench set, jack stands.
Sub-steps:
1. With the vehicle still elevated, check the suspension bushings and struts for signs of wear or damage.
2. Tighten any loose bolts and replace any worn components as necessary.
3. Perform a visual inspection of the wheel bearings for play or noise.

4. Tire Inspection and Balancing

Tools Required: Tire pressure gauge, wheel balancer (if available).
Sub-steps:
1. Check the tire pressure on all four tires and inflate to the recommended PSI.
2. Inspect tires for uneven wear or damage.
3. If necessary, have tires balanced at a tire shop to eliminate vibrations caused by imbalance.
