Gotta change the front bearings on my 99 Challenger.

I've done the sealed unit type ones in front wheel drives and I've done trailer bearings, and have a bearing puller, so I feel OK about removing the brake calipers and ripping the hub off.

However I have no experence with (non - constant) 4WD front hubs so am worried I'll take stuff off and then hear a "boiiinnng" and watch springs and cogs and sh!t go all over the place.

Is it as easy as removing the centre nut and away she comes?

I believe I have to remove the inner hub - drive shaft seal first with a circlip on it (?) and that is all that googling has shown me. In fact googling has found very little.....

EDIT: BTW I have no idea what the hubs are I just know I can stick it in fourby at up to 80kph, and it has no little dial thingo for freewheel and lock like the old school 4WD's had. Just a cap over the centre like a trailer hub has.
