Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and cool before beginning work.

2. Inspect and Balance Tires

Remove the wheel covers or hubcaps if applicable.
Use a tire pressure gauge to check and adjust tire pressures to manufacturer specifications.
Visually inspect the tires for signs of uneven wear or damage.
If needed, take the vehicle to a tire shop for balancing and alignment.

Raise the vehicle on jack stands and ensure it is secure.
Inspect the driveshaft for any play or damage; rotate the driveshaft by hand to check for smoothness.
Check CV joints for tears or leakage of grease; replace if necessary.

4. Inspect Engine and Transmission Mounts

Visually inspect the engine and transmission mounts for cracks or separation.
Use a pry bar to check for excessive movement in the mounts.
