some really good points that you sometimes overlook because you get tired of looking..yes I have a good cover/girdle,but yes I am also guilty of sanding the pinion gear for easier removal.my other car has a dana 60 that has all that stuff & never had problems ,but shim is also behind the race too.I will try that with the 12-bolt & see.as far as pre-load,Ive never measured it,just went by feel,and have used from "snug" to "tight",,I probably should actually measure it....as far as the pinion to bearing fit,I have some Green sleeve retaining loctite,will this help,plus maybe some carefully placed light center punches work to hold it in place?..I really appreciate all the answers & suggestions,if there are any more,I'll gladley listen as it will still be a couple of days before i start back toegther with it...........Thanks so much,Vic.......P.S. I also have some converter questions I'll ask in another thread if anyone wants to help

made my own solid design pinion spacer that used a shim along with front and rear holes to allow gear lube to flow thru machined tubular spacer. The spacer seemed to always show signs of loosness when tore down. MY Fix, pinion has ran five years now with no spacer between the bearings. If you want to try this always use a new G.M.pinion nut with heavy duty loctite, tighten nut to intended pinion preload and let set a day or two before running the car for loctite to harden. I use a 40 inch pound torque wrench to set the preload, it was designed to set the preload on jet engines and was military surplus when I bought it Good luck on fixing the problem, Ray |

on the "sanded bearing" idea...i have a used but in good shape bearing that is polished (sanded) to be able to tap it on and off for setting the pinion preload and clearance, then once the proper shims are selected i remove the bearing and install a new one. bearings have a high tolerance from one to the next, as long as you use the same manufactuer and p.n. each time you shouldn't run into clearance changes.
