2nd Gen Non-Engine/Transmission ONE Brake drum getting hot

[WBraico]

I have a 98. 5 3500 4x4 One rear brake drum(driverside) gets hot in normal city driving. I have jacked up the rear wheels there seems to be no more drag on one over the other side. Can the hot side be getting more pressure(fluid) than the other side? Has any one else had this problem?
