Solution

1. Preparation

Gather tools: jack, jack stands, tire pressure gauge, OBD-II scanner, torque wrench, and wheel chocks.
Ensure vehicle is on a flat, stable surface and the parking brake is engaged.

2. Tire Inspection

Remove any hubcaps or wheel covers.
Check tire pressure and inflate to manufacturer specifications.
Inspect tires for signs of uneven wear or damage.
If necessary, rotate tires to ensure even wear.

3. Wheel Balance and Alignment

If tires are out of balance, take the vehicle to a tire shop for balancing.
Perform a wheel alignment if the steering wheel is off-center or if there’s uneven tire wear.
Torque wheel lug nuts to manufacturer specifications after balancing or aligning.

4. Drivetrain Inspection

Safely lift the vehicle and secure it with jack stands.
Visually inspect the driveshaft for bent areas, and check the CV joints for tears or leaks.
Replace any damaged components.

5. Engine and Transmission Mounts

Inspect engine and transmission mounts for cracks or excessive movement.
If mounts are damaged, replace them with parts specified for the RAV4 model.

6. Suspension Check

Inspect suspension components, including struts, shocks, and control arms for damage or wear.
Replace any worn or damaged parts as needed.
