[Chumley60]

I had the exact same noise with my '95 Nissan pickup, except my squealing stayed on the left front. Replaced pads and turned rotors, no help. Had the bearings repacked and adjusted, they were fine. Even cleaned the rust between the rims and discs/drums. No change. After a few months of the neighbors knowing who was driving down the street, it went away. Comes back occasionally, but only for a few seconds when temperature is right. In my case it seems to be more an annoyance than a problem.
