year? model of jeep?
most early cj jeeps bolt in (hub & axle are 2 peices)
if your not removing the hub, remove the 4 bolts that hold the backing plate on and use a slide hammer to remove the axle from the housing, backing plate come with it, so disconnect and cap the brake line from the wheel cly.
if you think thats a pain in the ass, wait till you have to shim the axle end play(with shims behind the backing plate). major shitty design
