Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal.

2. Tire Inspection and Replacement (if needed)

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench.
Check tire pressure; inflate to manufacturer specifications if low.
Inspect tires for uneven wear; replace if necessary.
If replacing, remove lug nuts with the lug wrench, lift the vehicle with the jack, and replace the tire.
Reinstall lug nuts in a crisscross pattern to ensure even tightening; torque to manufacturer's specifications.

3. Driveshaft and CV Joint Inspection

Tools Required: Socket set, pry bar.
Remove the vehicle’s underbody shield if applicable.
Inspect the driveshaft for any visible damage or excessive play.
Check the CV joints for tears in the boot or signs of grease leakage.
Replace any damaged components; ensure proper alignment during reassembly.

4. Engine Mount Inspection and Replacement

Tools Required: Socket set, torque wrench.
Locate the engine mounts; inspect for cracks or excessive wear.
If a mount is defective, support the engine with a jack and remove the mount bolts.
Replace the mount with a new one and torque bolts to specifications.

5. Reassembly

Reinstall any underbody shields removed during inspection.
Reconnect the negative battery terminal.
Lower the vehicle safely back to the ground.
