Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery if working on electrical components.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check each tire.
Inflate or deflate tires to recommended pressure levels as stated on the driver’s door jamb.

3. Wheel Alignment

Tools Required: Alignment rack, torque wrench.
Center the steering wheel and ensure the vehicle is level.
Adjust the toe, camber, and caster angles according to manufacturer specifications.
- Typical toe angle for RAV4: 0.06° to 0.12°.
- Perform adjustments by loosening the tie rod lock nuts, turning the tie rods as needed, and re-tightening the lock nuts.

4. Inspect and Replace Worn Components

Tools Required: Socket set, wrenches, jack stands.
Lift the vehicle and remove the front wheels.
Inspect tie rods, ball joints, and bushings for signs of wear.
Replace any worn parts using the following procedure:
- Remove the securing bolts and nuts for the component.
- Install the new part and torque to manufacturer specifications (e.g., ball joint nut: 35 ft-lbs).

5. Suspension Inspection and Replacement

Inspect struts and shocks for leaks.
If replacement is needed:
- Remove the wheel and unbolt the strut from the top mount and lower control arm.
- Install new struts and torque bolts to specifications (typically around 50 ft-lbs for lower bolts).
