A friend of mine has a 93 W350 that he just bought, nice truck with a few minor issues such as the plastic selector to lock in the hubs is broke. He figures there must be problems inside to reason for the busted selector but anyways. He would like to rebuild the hubs but cant seem to find a decent price.

It seems as though I read somewhere that its just as well to buy new assembles. Either way whats the best option and where to go to get it?
