Hello. I have an 87 raider. The rear driver axle nut came loose and axle shaft came out. Got that side fixed and am having problems torquing the nut. I have no way to tell the actual torque. So upon taking passenger side shaft out to replace bearing I realized I could not get the axle nut loose. The manual calls for a spanner wrench but have not been able to find one. Finally put it back together and dropped it off at dealership to let them try. They removed the nut, but now say that the bearing is stuck. It is tapered. Can someone explain how this tapered bearing is seized on the shaft?
