A method of providing road and vehicle diagnostics, includes providing a vehicle axle system having a first axle half shaft housing, a second axle half shaft housing and a differential housing. Attached to one or more of the housings is one or more tri-axis accelerometers. In communication with the accelerometers is one or more data processors configured to receive and analyze data from the accelerometers. An occurrence of one or more road events is determined by one or more spikes in the Z-direction of the data collected from the accelerometers. A depth of the road event is determined by a magnitude of the positive and negative changes in acceleration of the spike in the Z-direction and a length of road event is determined by an amount of time between two spikes of opposite magnitudes in said Z-direction. Once identified, the time and geographic location of the road event is identified.
