Solution

1. Preparation

Gather tools: OBD-II scanner, jack and jack stands, torque wrench, socket set, and a visual inspection mirror.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Inspection

Remove the wheel covers or hubcaps if applicable.
Check tire pressure with a tire gauge and inflate as necessary.
Inspect the tread for uneven wear; replace any tires that show significant wear or damage.

3. Driveshaft Inspection

Safely lift the vehicle using a jack and secure it with jack stands.
Examine the driveshaft for cracks, dents, or signs of excessive rust.
Ensure that the universal joints are not worn by attempting to move them; they should not have excessive play.

4. Mounts Inspection

Inspect the engine and transmission mounts for cracks or separation.
If mounts are damaged, remove the necessary components to access the mounts.
Replace any mounts that are worn or show signs of failure.

5. Differential Fluid Service

Locate the differential fill plug and remove it.
Check the fluid level; it should be at the bottom of the fill hole.
If the fluid is low or appears dirty, drain the differential, replace the fluid with the manufacturer-recommended type, and refill.

6. Final Assembly and Testing

Reassemble any components that were removed during the inspection process.
Ensure all bolts are torqued to the manufacturer’s specifications.
Lower the vehicle and perform a test drive to confirm the resolution of vibrations.
