How many separate bearings/race/seal sets are there in the front diff? 3? Suppose I'll need any & all part #'s you've got...

Been experiencing an intermittent wobble in the front end. Did the inner & outer front wheel bearings a few weeks ago... Noticed this past weekend when rolling around under the rig that the pass. side driveshaft has a considerable amount of play at the diff (+1/4" up & down). Figured since I'm about to finally do my R&P, might as well have the bearings done at the same time - but since I just did the wheel bearings I don't need to buy a 'master kit'; Just need the ones in the diff. Can't seem to find the #'s or someone knowledgeable on the phone... Arrrgh. <img src="/forums/images/graemlins/shiner.gif" alt="" />
