After reading several posts on this site, it's apparent the bearing in the front, passenger side axle disconnect has a tendency to go bad for lack of grease. An entire unit is around $500. Has anybody tried to remove the bearing itself and replace it? Sure would be nice to do that instead of spending so much money. I'm guessing there's actually an inner and outer bearing. Seems to me if you could get the old bearings out it should be possible to match them up and replace them.
