Bump fo sum updates.
I'm about to finally finish up the axles that I built a few months back. To start, I decided to rebuild a used D30 true trac I picked up. By rebuilding it, I plan on fixing a common issue they have. The center cone spring system seems to work well, but causes the outer gears to wear against the casing. The one I picked up is no different. Not only does the casing start to wear, but the spring pressure decreases reducing the diff's ability to limit torque transfer. My plan is to machine the casing havles to remove the scoring, and install kevlar shims to eliminate the wear problem. It might sound like a lot of work, but I already have it...and I'm curious.

And the gear face that is wearing against the housing...
This is one of the cam bearings that exerts pressure to the gear
At the center of it all are two bevel washers that compress once the case ends are bolted to the center section. These washers act like the springs in a traditional LSD exerting pressure to both inner gears. Without them, the diff would operate just like any other open diff. The benefit of having the six worm gears are simply that they allow a stronger 1 peice center section.

I also fabbed up some rear spring pads, and plan to incoporate a rear sway bar.
Thats all for now, but I'll have more soon! :farmer:
