Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working.

2. Tire Inspection and Balancing

Remove the wheel covers or hubcaps if applicable.
Use a tire pressure gauge to check and adjust tire pressures to the manufacturer's specifications.
Inspect tires for bulges, cracks, or uneven wear patterns.
If tires are unbalanced, take them to a tire shop for balancing.

3. Wheel Alignment

Use an alignment tool or take the vehicle to a professional alignment shop.
Adjust camber, caster, and toe according to manufacturer specifications.

4. Drivetrain Inspection

Raise the vehicle using a jack and secure it with jack stands.
Inspect the driveshaft for any signs of damage or excessive play.
Check CV joints for torn boots or leaks and replace if necessary.

5. Engine and Transmission Mounts

Visually inspect all engine and transmission mounts for cracks or wear.
If mounts are worn, follow these sub-steps:
- Remove any components obstructing access to mounts (e.g., air intake duct).
- Use a socket set to remove the bolts securing the mounts.
- Replace with new mounts and torque bolts to the manufacturer’s specifications.
