they make kits for this w/ new axles, after you remove your axles you will have to remove the backing plates, remove the seal & bearing, cut off the end of the axle, reinstall backing plates, slide the new axle in w/the bearing assem installed on the axle, the new axle bearing assem bolts to the axle using the backing plate bolts (new ones), the new bearing assem is what holds the axle in, I think mine was from Moesure
