the centre is fixed, and the outer bearing carrier (hub) is fixed but moves up and down, if the axle that joins the wheel flange and the diff together is a set length then where is the give (if any) when the wheel moves up and down with suspension travel?
ie could you not forgoe the circlips that hold the splined axle shaft in the centre, as at worst on full suspension travel the centre hub may move in or out much like a driveshaft on a conventional gearbox, as long as it cant move to far in and munch the oil seal, where is the harm??? it cant fall out and may only move sideways a couple of mm at most?
am I on the wrong track
