After putting over 1100 miles on this thing since late-August, it's time to stick a little more gear and a limited slip in it. We compromised on a set of 4.10's, as that will keep the truck completely highway-friendly while offering a noticeable improvement in acceleration over the current 3.73's.

I started the install today (clockwise from top left). Pulling the drain plug, it was immediately evident that something wasn't happy. Removing the cover, more shrapnel was found. It seems that one of the 52 year old spider gear thrust washers wasn't up to the abuse dished out by the new drivetrain. The housing was stripped of everything, new bearing races were driven in, and reassembly began. The pinion is currently installed with the spec shim and mockup bearings. The diff is only set in place. Actual setup will take place tomorrow.
