Yea I was going to recheck the pattern since like you said there was probably no preload when putting it together. The axle didn't use the big slinger, so we left it off.With .070" of pinion shim, the bearings should require a good amount of preload shims to keep them from crushing. It looks like your pinions dont match in size and yes, that shoulder is longer. Did you order super duty gears and are you 105% sure you have a 60 and not a 50?
My real question is; How did you guys preload the pinion when running the patterns? If it was loose, your patterns were wrong. Your .070" is including the slinger right?
My 60 only took .037" with yukon gears and usa standard master. With the added thickness of the slinger, my total pinion shim stack was .068". (Slinger was .031")
But I'm still at a loss, the bearings are just flat out too far apart. If anything more pinion depth would help because then the shoulder would sit further down and allow it to preload. The pinion is stamped D60 513R, the box is the Yukon part number for 250/350 Dana 60s in this year range (this is an 03), and the sticker on the axle says 248 which should be a 60 and not a 50.
