It really does sound like a brake issue. To check you will have to jack it up and remove the wheel. Try to turn the hub, might need a 2x4 piece of wood. When turning you can see if the brakes (discs?) are dragging, discs will drag some. Drums? Take them off, rotate the hub. Make sure yer parking brake isnt pulling the brakes closed. JR

fastest way to see if brakes are draging is remove the drum and put the wheel back on and spin it by hand again if it moves easily then the brakes are dragging and either the shoes need to be adjusted in or the e-brake cable is being pulled ( sometimes when rear dif is hanging the drive line will pull down on the cable). Additive is a 4oz bottle that is added to the oil when you use a positraction unit. The heat generated by the posi unit clutches naturally repels oil and the clutches can run almost dry at that point which makes it grab way to much and wear out faster. The additive or friction modifier is a lubricant that is attracted to the harsher heat and keeps the clutch pack lubed.
