just pulled the axles out of my housing. 8.5 10 bolt 28 spline. i need to get the lenght to order new ones since the bearing surface has a groove worn into it and there is alot of play. do you go from the back of the wheel stud plate to the top of the axle? or from were the axle maching stops at the bottom up to the top of the axle? any help on this would be appreciated.
