I had front end-work done on my car. The mechanic, whom I know well, said my front hubs had 2 plastic washers (2 on each side) that needed replacing, but he couldn't find "just the washers." He's called around and everyone told him that the only way to get the washers is to buy the whole hub assy., a $300 cost. Needless to say I said leave them for now since I don't currently need/use 4WD.
What are these washers called? Who can possibly sell "just the washers"?
