Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.

2. Inspect and Replace Tires (if necessary)

Sub-steps:
- Remove the wheel covers or hubcaps if equipped.
- Loosen the lug nuts but do not completely remove them.
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheels and inspect the tires for uneven wear, bulging, or damage.
- If necessary, replace the tires with new ones of the correct size and specification.
- Reinstall the wheels, hand-tighten lug nuts, lower the vehicle, and torque the lug nuts to manufacturer specifications (typically around 80 ft-lbs for most Camry models).

3. Inspect and Replace Mounts (if necessary)

Sub-steps:
- Locate the engine and transmission mounts, usually found at the front and rear of the engine and under the transmission.
- Inspect for cracks, separation, or excessive movement.
- If mounts are damaged, remove the bolts securing the mounts to the engine and chassis using a socket set.
- Replace with new mounts, tightening to manufacturer torque specifications.

4. Check Driveshaft and CV Joints

Sub-steps:
- Raise the vehicle and secure it with jack stands.
- Inspect the driveshaft for bends, cracks, or loose connections.
- Check the CV joints for torn boots or excessive play.
- Replace any damaged components, ensuring all fasteners are properly torqued.

5. Suspension Inspection and Repair

Sub-steps:
- Examine struts and shocks for leaks or damage.
- Check bushings and ball joints for wear or play.
- Replace any worn components and ensure proper installation and torque.
