why does my Toyota RAV4 have uneven tire wear on the front tires?

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a flat surface and engage the parking brake.

2. Check and Adjust Tire Pressure

• Sub-steps:
  • Remove valve stem caps from all tires.
  • Use a tire pressure gauge to measure the pressure of each tire.
  • Inflate or deflate tires to meet the manufacturer's recommended pressure (found on the driver's door jamb).

3. Perform Wheel Alignment

• Sub-steps:
  • Drive the vehicle onto a professional alignment rack.
  • Follow the manufacturer’s specifications to adjust camber, caster, and toe settings.
  • Make necessary adjustments using an alignment tool and ensure all settings are within specifications.

4. Inspect and Replace Worn Suspension Components

• Sub-steps:
  • Raise the front of the vehicle using a jack and secure with jack stands.
  • Visually inspect struts, shocks, and control arms for wear.
  • Replace any damaged or worn components with OEM or high-quality aftermarket parts.

5. Inspect and Repair Steering System

• Sub-steps:
  • Check the condition of the tie rods, ball joints, and steering rack.
  • Replace any damaged components that may contribute to uneven tire wear.

6. Rotate Tires

• Sub-steps:
  • Remove all four tires using a socket set.
  • Rotate the tires according to the manufacturer's recommended pattern to promote even wear.
  • Reinstall the tires and torque the lug nuts to the specified value (usually around 80-100 ft-lbs).
