I have a 3-speed 1991 Audi 100 non-quattro and I am trying to find the right front wheel hub for it. All the dealers I call give me the part number 443407615A, but that hub does not fit at all. It is too loose for the bearing, and it doesn't match the pattern on the axle. The hub I keep getting has 26 splines, yet the axle has 38 splines. Nobody can seem to tell me what the right hub for the car is. Does anyone have any suggestions?
