Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Rotation

Tools required: Jack and jack stands, tire pressure gauge, torque wrench.
Check each tire for uneven wear, bulges, or punctures.
Ensure tire pressure is at the recommended level (found in the owner’s manual or on the driver’s door jamb).
If necessary, rotate the tires according to the manufacturer's specifications.

3. Driveshaft Inspection

Tools required: Socket set, torque wrench.
Inspect the driveshaft for any visible damage such as dents or cracks.
Check the universal joints (U-joints) for looseness or play.
Tighten any loose bolts to the manufacturer's torque specifications.

4. Suspension Component Check

Tools required: Socket set, pry bar.
Visually inspect all suspension components (control arms, bushings, etc.) for wear.
Use a pry bar to check for play in bushings and joints.
Replace any worn or damaged suspension components.

5. Engine and Transmission Mount Inspection

Tools required: Socket set, torque wrench.
Inspect engine and transmission mounts for cracks, wear, or separation.
If mounts are damaged, replace them with OEM or equivalent parts.
Tighten all mounting bolts to the manufacturer’s torque specifications.
