I am in pretty desperate need of some new u joints. Put new Napa joints in about 15k miles ago, now have a cracked cap on one of them. I would like to go back to OEM. I found places to order them, but nothing specific to a 97 f250. I would go through the dealer, but they have a new parts guy and I really don't want to deal with getting the wrong parts. To get new u joints for the front driveshaft took over an hour of looking, don't have the time for that. Where do I get them and does anybody have part numbers for the rear driveshaft? If I have to go back to the dealer I will, but would like an alternative. I would appreciate any help.
