quick 8.75 axle guestion

The maximum is over 1/4 inch, when the adjuster falls out.
Sometimes you have to bop the adjuster side axle with a big hammer and a hardwood block, to drive the other side out as far as it will go. This is usually because the housing is bent, or the bearing bore is damaged, or the bearing is not seated properly,due to hanging up on something;like a backing plate or a gasket.Do not attempt to drive it through with the adjuster-side nuts. You will end up ruining the retainer-plate
PS; you did back off the adjuster..........right?
