Back to Generation

If your 2020 Toyota Highlander is experiencing a rough ride despite proper tire inflation, there could be several underlying causes. Below, you'll find a detailed guide to diagnose and potentially fix the issue.

Tools Required
  • Tire pressure gauge
  • Jack and jack stands
  • Torque wrench
  • Socket set
  • Wrench set
  • Suspension check tool (if available)
  • Alignment machine (if available)
  • Tire balancing machine (if available)
Repair Instructions

Step 1: Tire Inspection

  1. Check Tire Pressure: Use a tire pressure gauge to confirm that all tires are inflated to the manufacturer’s specifications (found in the driver’s door jamb).
  2. Examine Tire Condition: Look for signs of damage or uneven wear. If necessary, rotate tires to ensure even wear.

Step 2: Suspension Component Check

  1. Lift the Vehicle: Use a jack to lift the vehicle and secure it with jack stands.
  2. Inspect Shocks/Struts:
    • Check for any oil leakage.
    • Perform a bounce test: Push down on each corner of the vehicle; if it continues to bounce more than once, the shocks/struts may need replacement.
  3. Examine Bushings and Control Arms: Look for cracks or excessive wear. Replace any damaged components.

Step 3: Wheel Alignment

  1. If you suspect misalignment, take the vehicle to a professional alignment shop.
  2. If you have access to an alignment machine, follow the manufacturer's instructions to adjust the alignment to factory specifications.

Step 4: Wheel Balancing

  1. If vibrations are present, have the wheels balanced at a tire shop.
  2. Follow the shop’s instructions for weight placement according to the machine's readout.

Step 5: Steering System Inspection

  1. Check for Play: With the vehicle lifted, grab the tire at 12 and 6 o'clock and shake. If there is play, inspect the tie rods and steering rack.
  2. Replace any worn components as necessary.

Step 6: Test Drive

  1. After performing all checks and repairs, take the vehicle for a test drive to evaluate the ride quality.
  2. Pay attention to any vibrations, noises, or handling issues.
Conclusion

If, after completing these steps, the rough ride persists, it may be best to consult a professional technician or a Toyota dealership for a more in-depth diagnosis. Potential issues may include internal suspension problems or electronic stability control (ESC) system malfunctions, which require specialized diagnostic tools.
