Solution

1. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure in each tire.
Inflate or deflate tires to match the recommended pressure found on the door jamb sticker.

2. Tire Rotation and Balance

Tools Required: Tire balancing machine, jack, jack stands, lug wrench.
Raise the vehicle using a jack and secure it on jack stands.
Remove the wheels using a lug wrench.
Mount each tire on the balancing machine and adjust weights as necessary to achieve balance.
Reinstall the wheels, tightening lug nuts to the manufacturer’s torque specifications (typically 76 ft-lbs for Toyota).

3. Suspension Inspection and Repair

Tools Required: Socket set, torque wrench, pry bar, and possibly a spring compressor.
Check for leaks in the shock absorbers or struts. If leaks are present, replace the damaged components.
Inspect the control arms and bushings for wear. Replace any worn or damaged parts.
If necessary, replace shocks or struts by:
- Removing the retaining bolts and disconnecting the shock/strut assembly from the vehicle.
- Compressing the coil spring using a spring compressor.
- Installing new components in reverse order of removal, ensuring all bolts are torqued to the manufacturer's specifications.

4. Wheel Alignment

Tools Required: 4-wheel alignment machine.
After any suspension work or tire replacement, perform a 4-wheel alignment.
Adjust the alignment settings to match the manufacturer's specifications for camber, caster, and toe.
