A novel temperature probe provides a visual indicator to an operator of when an assembly, such as a vehicle axle, filled with a semi-fluid synthetic grease for lubricating the bearings therein has reached an unsafe temperature during operation. In one embodiment, the temperature probe is provided in a specially drilled bore through one of the components. In another embodiment, the temperature probe is provided in a bore drilled into a fastener member which is normally used in the assembly. The temperature probe includes an indicator pin which is mounted in a housing. When the components reach an unsafe temperature during operation, the indicator pin pops outwardly from the housing to alert a user that an unsafe temperature has been reached.
