Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Engage the parking brake and wear safety gloves and goggles.
Gather tools and parts required for the repair.

2. Tire Inspection and Balancing

Tools Required: Tire pressure gauge, jack and jack stands, torque wrench.
Check tire pressures and inflate to the manufacturer's specifications.
Inspect tires for uneven wear or damage; replace if necessary.
If tires are in good condition, balance them using a tire balancing machine.
Torque lug nuts to the manufacturer's specifications (typically 76 ft-lbs for RAV4).

3. Suspension Component Inspection

Tools Required: Socket set, torque wrench, pry bar.
Raise the vehicle using a jack and secure with jack stands.
Visually inspect suspension components for any signs of wear, such as torn bushings or damaged struts.
If any components are damaged, replace them as necessary. For example, replace control arm bushings with a torque specification of 40 ft-lbs.

4. Driveshaft and CV Joint Inspection

Tools Required: Wrench set, flashlight.
Inspect the driveshaft for any visible damage or excessive play in the CV joints.
If worn, replace the CV joint or driveshaft assembly as needed.

5. Engine Mount Inspection

Tools Required: Socket set.
Check the engine mounts for cracking or separation.
If the engine mount is damaged, replace it with a new mount, ensuring to torque the mount bolts to the specified value (usually around 40 ft-lbs).

6. Transmission Fluid Check

Tools Required: Fluid pump, funnel.
Remove the transmission dipstick and check the fluid level and condition.
If low, add the recommended transmission fluid (typically Toyota Type T-IV).
If contaminated, perform a transmission fluid change.
