my Toyota RAV4 feels unstable at high speeds, what could be causing this

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a flat surface and ensure it is secure.
• Disconnect the battery if working on electrical components.

2. Tire Inspection and Replacement

• Inspect Tires:

  • Remove the wheel covers if applicable.
  • Check for proper tire pressure; inflate as needed.
  • Inspect for uneven wear; replace tires if tread depth is below 2/32 inches.

• Replace Tires (if necessary):

  • Loosen lug nuts with a socket wrench before raising the vehicle.
  • Use a jack to lift the vehicle and secure with jack stands.
  • Remove the lug nuts and tires, then install new tires.
  • Torque lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

3. Suspension Inspection and Repair

• Inspect Suspension Components:

  • Check struts, shocks, and springs for leaks or damage.
  • Replace any worn or damaged components; use appropriate tools for removal (e.g., socket set, spring compressor).

• Install New Components (if necessary):

  • Follow specific manufacturer's instructions for installation.
  • Torque bolts to specified values, ensuring all connections are secure.

4. Wheel Alignment

• Perform Wheel Alignment:
  • Take the vehicle to a professional alignment shop or use an alignment machine.
  • Adjust camber, caster, and toe settings to meet manufacturer specifications.
