Abstract: Methods and apparatus are provided for predicting potential failure of wheel bearings in a vehicle. The apparatus includes a temperature sensor configured to measure a temperature value for a wheel bearing and a processor for comparing the temperature value to a threshold value. When the temperature value exceeds the threshold value, the process provides an indication to warn of the potential failure of the wheel bearing. The method includes operating the vehicle for a time period and measuring a temperature value for the wheel bearing after the time period. Next, the temperature value is compared to a threshold value for the wheel bearing. When the wheel bearing temperature value exceeds the threshold value, and indication is provided to warn of the potential failure of the wheel bearing.
