Solution

1. Preparation

Gather all tools and parts necessary for repairs.
Ensure the vehicle is parked on a level surface and the ignition is off.
Engage the parking brake for safety.

2. Check and Adjust Tire Balance

Tools Required: Wheel balancer, torque wrench.
Remove the wheel covers or hubcaps if applicable.
Mount the wheel on a wheel balancer and spin to check for imbalance.
Add or remove weights as necessary to achieve proper balance.
Reinstall the wheel and torque to manufacturer specifications (typically 76-87 ft-lbs for Highlander).

3. Tire Pressure Adjustment

Tools Required: Tire pressure gauge, air compressor.
Use the tire pressure gauge to measure the pressure in each tire.
Inflate or deflate tires to match the manufacturer’s recommended pressure (usually around 32-35 PSI for the Highlander).

4. Wheel Alignment Adjustment

Tools Required: Alignment rack, alignment tools.
Place the vehicle on an alignment rack and perform a four-wheel alignment check.
Adjust camber, caster, and toe settings as needed to meet manufacturer specifications.

5. Suspension Component Inspection and Replacement

Tools Required: Socket set, jack stands, pry bar.
Inspect all suspension components including control arms, bushings, and struts for wear.
Replace any worn components with OEM or quality aftermarket parts.

6. Drivetrain Inspection

Tools Required: Jack, jack stands.
Inspect CV joints and u-joints for play or damage.
Replace any damaged joints with new ones if excessive wear is detected.
