I'm going to be taking my 2000's rearend apart because my driverside bearings are going out and I was going to replace some stuff to heavier duty stuff to handle the cars Torque better including the Axle Splines, does anyone have a recommendation of which product to use??? Moser Axle Splines? Superior Axle Splines?? Ford Racing Axle Splines?? Also, how do I know if my car uses the 5 Lug/28 Spline or the 5-Lug/31 Spline?? Also best place to purchse it?? Any thoughts or advice would be appreciated!Thanks
