Huh?
The sensor is at the top if my memory is correct. The oil level is well below that mounting point, and just above the point where it will spill into the hub.
If the differential needs to be flushed to remove crud wouldn’t the solvent or flushing liquid need to be excessively over filled, something which requires a modification to the fill hole in the pumpkin using some plumbing fittings to raise the inlet well above the current opening?
You can’t drive the coach with flushing liquid in it so how do you get the necessary agitation to remove and carry crud away?
