This is a right axle and axle housing for a John Deere 425 rear end. This part will also fit a 445 and 455 tractor. The part number for the Right axle is M806170 and the housing number is AM88196. These parts are in good used condition. The axle splines do show a little amount of wear, the wheel stud holes are in good shape, and the axle end bearing seems to be nice and tight. (26b)
