A method of providing road and vehicle diagnostics. The method includes providing a vehicle axle system having a first axle half shaft housing, a second axle half shaft housing and a differential housing. Attached one or more of said housings is one or more tri-axis accelerometers. In communication with the accelerometers is one or more data processors operably 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 said data collected from said accelerometers. A depth of the road event is determined by a magnitude of said positive and negative changes in acceleration of said spike in said Z-direction and a length of road event is determined by a span of said one or more spikes in said Z-direction. Once the road event is identified the time and geographic location of the road event is identified.
