i tried looking for info on your rig, but this massive 77 page thread is kinda ridiculous LOL, (in a good way)
who built the rear case? how old is the bearing next to the broken teeth on the counter shaft? is it a new or used bearing?
is/are/were the #1 and #2 housings paired from the factory? what condition is the main bearing in? for that matter, how do all the bearings look? did you replace them all after the first set of gears went bad?
also, what engine you running? hp? trans? tire size?
when i first saw these pics, i thought it was a bit odd...
also, what number gear set are these?
the rear case was built by a friend who owns a toyota specialized off-road shop in Colorado, I have complete confidence in his abilities.
I couldnt tell you how old te bearings may or may not be, but i did check everything over for excessive wear or heat issues or slopiness and everything looks fine. these sets of gears i broke were in two different cases. I didnt break one set and then put new gears back into that same case, so there should be no issues with broken metal in the bearings or something like that
i couldnt tell you what # the gearset is, i dont know where to find that out
