Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and cool.

2. Inspect and Replace Tires (if necessary)

Sub-steps:
1. Remove the wheel covers (if applicable) using a flathead screwdriver.
2. Loosen wheel lug nuts using a socket wrench but do not completely remove them.
3. Jack up the vehicle and secure it with jack stands.
4. Remove the lug nuts and take off the wheels.
5. Inspect for uneven wear patterns; replace tires if necessary.
6. Reinstall the wheels and torque lug nuts to manufacturer specifications (typically 76 lb-ft for Toyota Corolla).

3. Check and Replace Suspension Components (if worn)

Sub-steps:
1. Use a socket set to remove any protective covers obstructing access to suspension components.
2. Inspect control arms, struts, and bushings for wear.
3. Replace any worn components with OEM parts.
4. Reassemble any removed components and ensure all fasteners are torqued properly.

4. Inspect and Replace Engine and Transmission Mounts (if necessary)

Sub-steps:
1. Locate the engine and transmission mounts.
2. Use a wrench to check for any looseness or cracks in the mounts.
3. If damaged, remove mounting bolts and replace with new mounts.
4. Tighten all bolts to the specified torque values (consult the service manual for exact values).

5. Final Inspection

Sub-steps:
1. Recheck all wheel lug nut torques after reinstallation.
2. Lower the vehicle and perform a final visual inspection.
3. Test drive the vehicle to ensure vibrations are resolved.
