The bearing will cost $75.00 to $100.00 for the part with the final price around $350.00 to $450.00 with most of the cost being labor . With that labor cost in mind it may pay you to spend a little more and replace the Bellows/boots if they are getting into their third year or more, other wise you may end up spending that same amount of labor again to relace those items a short while later.
