Oil change in a diff without drainplug or cover
In my 64/98 I want to change the oil in the diff, but havent got a gasket if taking the diff apart, but is it possible get a hose in through the filler hole and suck it out with a vacuum pump, of will I have to remove the complete gear??

But a sealant like RTV would be sufficient if not having a gasket is good to know, thanks :-)

Yes its a chore,
Have to jack up the rear, remove rear tires and wheels disassemble the rear brakes remove the backing plate, remove the rear axles, remove the drive line unbolt the center section and loosen to drain oil into a pan then remove rear. clean out the muck at the bottom of the housing and then reverse the process filling with new recommended oil usually 90 weight.
Things to check while you have it apart
brake shoes or pads
axle bearings and seals
pinion seal
replace above as needed
This can turn into a MAW in a hurry

Not so much sludge just fluid evaporation so it looses it viscosity and becomes tar again....plus contamination of metal from bearings and gear which become a silt of sort. lol. too much heat will do that to oil.
