I have two questions about the front wheel bearings and the input shaft size. I know that some year models have the front bearings that are dealer only as far as repacking, how can I tell if I have those bearings. I'm wanting to get this done pretty soon and I have always done it myself. If I have the dealer only bearings is it possible to change my front hubs with another year model so I can do it myself in the future. On the input shaft I saw a post that said that the 1 1/4 shaft size was changed to the 1 3/8 size starting in 2000. How can I find out if I have the 1 3/8. My truck is a 2000 year model and was built in Dec. 1999. Thanks in advance for the help
