why does my Toyota Highlander shake when I’m driving at high speeds

Solution

1. Tire Inspection and Replacement

• Sub-steps:
  1. Use a tire pressure gauge to check tire pressures and inflate to manufacturer specifications.
  2. Inspect tires visually for bulges, cracks, and uneven tread wear.
  3. Replace any damaged tires with new ones of the same size and type.

2. Wheel Balancing

• Sub-steps:
  1. Remove the wheel and tire assemblies from the vehicle.
  2. Use a wheel balancer to check for imbalance.
  3. Add weights as necessary to achieve balance.
  4. Reinstall the wheels and torque the lug nuts to manufacturer specifications.

3. Wheel Alignment

• Sub-steps:
  1. Lift the vehicle on a hydraulic lift or jack stands.
  2. Use an alignment machine to check the alignment settings.
  3. Adjust the toe, camber, and caster angles according to manufacturer specifications.
  4. Test drive to confirm improvement.

4. Suspension Component Inspection

• Sub-steps:
  1. Visually inspect shocks, struts, and bushings for any signs of wear or leakage.
  2. Replace any worn or damaged suspension components.
  3. Reassemble and ensure all fasteners are torqued to specifications.

5. Brake System Check

• Sub-steps:
  1. Inspect brake rotors for warpage by measuring with a micrometer.
  2. Replace warped rotors and inspect pads for uneven wear.
  3. Ensure calipers are functioning properly and not sticking.

Tools Required:

• Tire pressure gauge
• Wheel balancer
• Alignment machine
• Hydraulic lift or jack stands
• Socket set
• Torque wrench
• Micrometer

Parts Required:

• New tires (if necessary)
• Wheel weights (if balancing)
• Suspension components (if worn)
• Brake rotors and pads (if needed)

Estimated Repair Time: 3-5 hours

Safety Warnings:

• Ensure the vehicle is on a flat surface and securely supported before working underneath.
• Always wear safety goggles when working with tires and suspension components.
