I load it by hand, I cant get a wrench on the ring gear bolts becasue the posi unit is in the way as well as the extra large aluminum caps. I can get a socket on but can only turn it very little before it hits the caps. I am getting ready to take a look at your links.
I did some research over the weekend and I am begignning to think maybe my carrier preload and pinion preload may not be tight enough. Even though these bearings may only have 100-200 miles on them should I still set them as tight as new bearings? I have an old axel with the splines cut off and a nut welded to the spline end of the axel about a 5 inch long tool. I stick it in the carrier and use an inch pound tourqe wrench to measure carrier preload. I have about 15 inch pounds on it. Also the cap bolts, in the Yukon manual it say 60 ft/lbs, the Motive manual says 80-85 ft/lbs. Which is it? They are 1/2 bolts with 3/4 heads.
