Greetings all,
My forward pinion bearing and race rusted and started making a growling noise so I'm doing new ring and pinion gears and installing ARB air lockers while I'm in there. I'm struggling a bit understanding the right way to set pinion depth on the 8.25 or if you even need to. On disassembly, there were no shims installed, and the only ones that came with my G2 master pinion install kit are the smaller ones for the forward (small) bearing and race, so they would not increase pinion depth but only change preload, which I understand to be unnecessary on the 8.25 due to the crush sleeve.
I spent hours grinding down the old races to make test or fitting races that don't have to be pressed in to set the preload, but there are no shims in the kit to put behind the larger rear race to increase pinion depth. I'm not sure if I need that yet or not, but I'm hesitant to install the pinion and carrier and pattern the gear contact without having a way to adjust pinion depth if necessary. I also don't know whether to install it with the old or new crush sleeve or not at all to test the pattern, or which nut to use to seat the yoke and bearings.
Appreciate any help getting this done right. Thanks.
