"You do not need to remove the axle from the wheel hub before you start but I recommend you press the axle out or at least break its hold on the wheel hub before you loosen or remove everything. If you remove the knuckle and the axle is stuck to the hub it is a pain to get a puller on it later. Please see our article on axle removal for further assistance."

Is there enough room/play in the axle shafts to rear differenial to press the axle out of the carrier? I'd hate to press on the axle with the puller and have the axle damage my differential.

With the rear suspension arraigned as it appears in the photo, hanging down and unsupported the axle joints are in a position where they are most extended and therefore you have some space available as you collapse them while pushing the axle stub from the hub itself.

There is enough "play" in the axle's joints to allow a puller(being used as a presser!) to budge the axle stub in the wheel carrier but there is not enough space to allow the axle to be completely removed without disconnecting some of the rear suspension links. So you could break it free so to speak and then disconnect the links allowing the wheel carrier to be pulled off the axle stub. There are cautions about over-extending the axle joints in the FSM so it's best not to be pulling on the axle if it remains connected to the diff as you do all this.

If you don't disassemble the rear suspension taking care to only disconnect thing at their non-adjustable ends you will likely need a rear suspension alignment after you put thing back together positioned differently than their original adjusted positions.

You would be wise to check with the machine shop that they are aware and competent to install the bearing as the failure to do so properly will often result in damage to the bearing itself and cause a premature failure before long.
