I have a 99 F250 with a bad front left wheel bearing and am trying to figure out which bearing assy I need to order. I have 4 wheel ABS and everywhere I look for the correct bearing it states "built after 3/22/99". The sticker on my door jamb says 02/99.

515020 is listed on Advance Auto website with the "after 3/22/99". I'm told the difference is in the rotor. Advance also lists a bunch of other bearings when you search for front wheel bearing that are only 8-10 bucks each. What are these? Are these for the 99's built before 3/22/99?

Powerstrokeshop.com says I can either get the 515020KIT for $300 and order the newer rotor at $98 or use the old style at $347 plus the seals, studs and nuts and use the old rotor, obviously the first is the better deal.

Advance Auto lists a bunch of different rotors, the cheapest being 32 bucks and they all say they fit '99 strokes with VIN "F". Which position in th VIN would this 'F' be? If I ordered the newer style hub kit which rotor would I need from Advance?

PLEASE HELP!!!
