Auto Parts: wheel barrens, ford windstar van, rear wheel bearings

Question
I have a 1998 ford windstar van and need to replace right barrens.How do I do this? Is it hard?

Answer
    I gather that whoever conveyed this information to you had a rather strong accent.  What he is referring to, I hope, is the wheel bearings.  Replacing the rear wheel bearings is fairly simple, they are held in place by a nut.  The entire assembly is in one piece, and is purchased in that condition for about $60.  The front wheel bearing is just the bearing, and installation requires several special tools including a press.   I would recommend having the front ones done by a pro, but you could probably tackle the rear ones by yourself if you have been accustomed to replacing brake pads, spark plugs, etc.
