During my rear disc conversion, I noticed something odd.... One of my hubs is smaller than the other...? When I got the 14B FF axle, the brakes on it were, what I believe, to be the one ton brakes. I had to replace a hub due to a sealing issue, and I'm wondering if one of my hubs could be 3/4 Ton, and the other 1 Ton? Can anyone shed some light on this for me? I think this may be causing a vibration I have been trying to track down. Here are <a target="_blank" href=http://photos.yahoo.com/bc/stoopalini/lst?.dir=/Hub+Diff&.view=t>some pics of the different hubs</a>. Look at where the hub overlaps the rotor, and you will see what I mean. The Driver's side hub is smaller. Thanks for any help ..... Thomas.
