ARP hub studs installed with a little oil on the threads, very snug fit.
Got a new spindle for the passenger side. Went with Fuji brand from YotaMasters. looks like a very nice piece and made in Japan. Front end gets a full rebuild.
Installing the diff came with some unexpected difficulties. The 4cyl diff studs are too short for the beefed up HP housing. longer studs from Marlin fixed that (part #MCHT-345). If anyone has the Toyota part number for these studs post up.
Minimal grinding on the axle housing was necessary to get the diff to fit. The ARB and heavy duty housing really add some weight to the diff, that and worrying about the air line made for a fun time test fitting. I cant say enough good things about the lube locker gaskets.
