my Toyota RAV4 Fifth Generation (2019-present) has uneven tire wear what's causing it

Solution

1. Preparation

• Gather tools: tire pressure gauge, alignment tools, jack and jack stands, torque wrench.
• Ensure the vehicle is on a flat, stable surface and the parking brake is engaged.

2. Adjust Tire Pressure

• Use a tire pressure gauge to check the air pressure in each tire.
• Inflate or deflate tires to match the recommended pressure found in the driver’s door jamb or owner’s manual.

3. Wheel Alignment

• Remove the front wheels: Loosen the lug nuts and lift the vehicle with a jack. Secure it on jack stands.
• Perform the alignment:
  • Attach alignment tool to the vehicle.
  • Adjust the camber, caster, and toe settings as per manufacturer specifications.
  • Tighten the adjustment bolts to the specified torque values (typically 50-70 ft-lbs).
• Reinstall the wheels: Place the wheels back on, hand-tighten the lug nuts, then lower the vehicle and torque the lug nuts to the specified value (typically 76-85 ft-lbs).

4. Inspect and Replace Suspension Components (if necessary)

• Check for signs of wear in the suspension system (shocks, struts, bushings).
• If any components are worn or damaged, remove and replace as follows:
  • Remove the damaged part: Use the appropriate socket and wrench to detach the component from its mounting.
  • Install the new part: Position the new component and secure it using the manufacturer-recommended torque specifications.

5. Tire Rotation

• Rotate tires based on the vehicle's maintenance schedule (typically every 5,000-7,500 miles).
• Ensure the tires are moved to appropriate positions to promote even wear.
