Working on the 1993 4x4 2500. Although I wrote the book on changing front rotors I am scratching my head over this one.
I got a loud squeal noise when the truck is warm going down the road. Stone cold there is no noise. Sounds like an oil seal not a brake pad squealer. The next day around 35 MPH it sounds like I suddenly put off road tires on the truck, but, this noise is kinda coming from the back. Sounds like dry ball bearings.
I put the wheels in the air and get the squeal from the passenger side front wheel. Figuring the Precision hub bearing is going bad. (And it doesn't have that many miles on it.) The test of the rear was inconclusive. Only when running the engine did we get gear noise, but, only one wheel was spinning in the air.
Oil in the diffs look ok.
I did get things wet enough for the drum brakes to grab hard while stopping. Like 1/8 mile of flooded road during our last storm some weeks ago. Is it possible for water to ruin a hub bearing?
