Welp, I replaced it, quite an easy job and can be done in under an hour.

The old fan clutch definitely has something wrong with it seeing it freewheels with little or no resistance when cold and when hot. I put it on a stove to heat it up and it did nothing but like to freewheel after about 2 revolutions.

The new one is a lot stiffer and like to roar pretty loudly when you first pull off when it is cold. At about 2000rpms it disengages and only come back on when you sit for a bit.

The truck does warm up a lot faster.

I think this was my weird dry squeaking noise. I don't think there is any fluid left in the old clutch.
