Ok ive got a small update.
The D60 is stripped and cleaned:
My air leak was a rupture in the soft copper tube for the locking collar for the ARB. So thats out
The o-rings are not in bad shape...
...but the new collar comes with the updated quad-rings, so of course they went in
ARB ready for reinstallation:
At this point, the ARB is back in and pressure tested; all is good.
I have a growing pile of parts in the garage:
Im expecting 5(?) more deliveries before i have everything to finish the truck. One of those is my new springless kingpin caps, which i wont get until next week, so i cant reassemble the D60 just yet. So i tore into the D70 today. Apparently i ordered the wrong wheel bearing hub seals! Also, i need repair sleeves for the spindles which im currently researching (proving to be a challenge to find the right ones). Also, my caliper brackets are wallowed out and need to be replaced so it looks like im pretty much buying a whole new disc brake kit, once i can find one with the correct offset for my housing, which i am also having trouble finding. I may have to buy a weld-on kit, or try and make my own.
So yeah, not much accomplished, and it looks like itll be at least another week, before i have all the parts required to finish rebuilding either axle.
