F60L Cab 12 truck

Shane,

As far as your diff goes, one must ask the question "Why touch it?"

There will only be foreign matter in it if there has been some major problem (Broken internals, torn seals or it has been submerged in a muddy creek)

Putting degreaser, kerosene and pouring hot water in it is only going to start the almost permanent "lining" of the housing coming loose and creating blobs of toffee to go into the bearings and causing seals to leak. Who cares what is coating the non-contact surfaces - it might even cut down on noise! The only thing that matters is the contact surfaces of the gears and bearings.

I would just be draining the oil, checking for unusual contamination and filling with recommended oil. One oil change to remove any loose sludge picked up by use after say 1,000km should almost do for the rest of the vehicle's life if it is used as a show/club truck only.
