Remove the wheel covers if applicable.
Check tire pressure and inflate to the manufacturer's specifications.
Inspect tires for uneven wear or damage; replace if necessary.
Balance the tires using a tire balancer.

3. Wheel Alignment

Use a wheel alignment tool to assess alignment settings.
Adjust the camber, caster, and toe settings to match manufacturer specifications.
Tighten all adjustment bolts to the specified torque values.

4. Inspect Driveshaft and Axles

Raise the vehicle using a jack and secure with jack stands.
Visually inspect the driveshaft for any signs of bending or damage.
Check axle boots for tears; replace if damaged.
If necessary, replace the driveshaft or axle that shows signs of failure.

5. Suspension Component Inspection

Inspect shock absorbers and struts for leaks or wear.
Check control arms and bushings for play or damage; replace if needed.
Tighten any loose bolts in the suspension assembly to the manufacturer's torque specifications.

6. Motor Mount Inspection

Locate and inspect the motor mounts for any signs of wear or cracking.
Replace the motor mounts if they show significant deterioration.
Reinstall the engine and check for proper alignment.
