Solution

1. Preparation

Tools Required: Jack and jack stands, torque wrench, OBD-II scanner, tire balancing machine, basic hand tools.
Safety Warnings: Ensure the vehicle is on a level surface and securely supported on jack stands before working underneath.

2. Tire Inspection and Balancing

Remove the wheels using a lug wrench.
Inspect tires for uneven wear, bulges, or damage; replace if necessary.
Balance the tires using a tire balancing machine; ensure weights are correctly placed.
Reinstall wheels and torque lug nuts to the manufacturer’s specification (typically 76 ft-lbs for Toyota RAV4).

3. Drivetrain Inspection

Inspect the driveshaft for any signs of damage or excessive play; replace if necessary.
Check CV joints for wear; replace if there are any tears in the rubber boot or if the joint is noisy.
Verify that all bolts on the driveshaft and CV joints are properly tightened.

4. Mounts Inspection

Check engine and transmission mounts visually; look for cracks or separation in rubber.
If mounts show signs of wear, replace with OEM or high-quality aftermarket mounts.
Ensure proper alignment and torque specifications when installing new mounts.

5. Suspension Components Inspection

Inspect control arms, ball joints, and bushings for wear or damage.
Replace any worn suspension components to ensure proper alignment and handling.
