What lubricating grease should be used in automotive wheel bearings that are exposed to a wide range of temperature conditions?

Most lubricating greases for automotive wheel bearings must meet the NLGI GC-LB or SAE J310 requirements.  Both of those specifications require that the grease must operate over a temperature range of -40 °C (-40 °F) to 160 °C (320 °F).  This covers the vast majority of driving conditions.
