In most cases one of the differential units will be naturally lubricated, but there are some medical conditions that may interfere with this natural lubrication and so require a little extra "greasing of the wheels." If the units are similar units then lubrication will likely be required. If differential units are joined at a non-standard junction lubrication will also probably be necessary.

Unless you have a 4x4 or 6x6 unit, there is no front differential.
because machine want lubrication with out lubrication machine parts will be damaged
so they can move
(1) Wheel bearings need lubrication or are about to fail. (2) (if an AWD model) the differential is low on lubricating fluid. If your question is in regards to its 'whining' when moving in reverse - that is normal.
Yes, the differential pressure switches off the thermopac. Differential pressure switch shut off unit in case of abnormal thermic fluid flow condition.
Most diesel-electric locomotives use electrical transmission and each wheel is driven individually by a electrical motor, rather than drive shafts. So there is no differential unit on these locomotives.

Lubrication of moving parts.
The speed sensor ring is in the differential case in front of the ring gear. To get to the unit you will need to remove the differential cover and drain the lube which requires replacement along with the cover gasket. Check to find out what lube you need to use and if synthetic is required. If you are not familiar with differential or transmission work you may want to get an estimate from a transmission shop or your mechanic.
That will depend on which differential you have. There is more than one. Find the metal tag located under one of the differential cover bolts on the rear end housing.
The 2001 Pontiac does not have any lubrication points. All of the components on the automobile are sealed and do not need to be lubricated.
