I think one of my brakes is dragging. I replaced one of the rear axle oil seals and after I reassembled it, it was struggling to move. It does move now, but if I am in High gear reverse is wants to die. So I am thinking one of the brakes is to tight. Does anyone have any suggestions on how I can tell which one is sticking without removing the tracks? I have event in 2 1/2 weeks and I don't want to remove the tracks again if I don't have to.
