hzj75 ute , clutch or gearbox broken??? with some pics

hi guys

today while taking off from a stop sign in my ute i got a loud BANG which sounded like it came from the gearbox / clutch area it was just as it loaded up and i began to take off then quite a violent bang . and to make it worse i had to get towed home by a nissan :doh:

i did notice one thing over the past week when coming to a stop like rolling along and push the clutch in and stop sometimes on the odd occasion would give a "clunk" from the gearbox / clutch area and seemed to be getting slighly more frequent i though it may be drive shaft clunk and was goin to grease it untill this happened

now ive had a bit of a look and this is what ive come up with so far anymore suggestions / things to check out would be helpfull.

with the car running you can select all gears WITHOUT pushing the clutch in but no drive engages, tail shaft doesnt spin and car does'nt move. a very slight grind as u run the shifter thru each gear can be felt ( like if you dont push the clutch in far enough and shift)
pedal feels fine, master / slave work , axle caps are still on.
my guess is the clutch ?? i really hope its not the box or input shaft ( you wouldnt feel the gears running if the input shaft had snapped right ? plus just taking off surely wouldnt do it ?)

could it be possible the clutch has lost all clamping pressure or a broken disk and im not up for a new gearbox yet :confused:

cheers for any imput.

I did check that transfer was engaged trap for young players that one lol. I tried in 4h/4l/2h even with the front hubs locked in nothing no drive anywhere :( I might get a chance to drop the box this weekend and have a look , would be nice to pin point what's self destructed has anyone else had a clutch/ gearbox let go like this I'm really sus on the clutch it was shuddering quite a bit and slipping a bit I think the turbo may have killed it lol. I've had a clutch let go before in another vehicle was a very similar feeling accept it was stuck in 2nd gear
 
ok so it was the gearbox/transfer clunking , stripped output shaft and gear it was also jumping out of 5th, oil wasnt pretty coming out of either so ive decided to put a new box in and a excedy h/d clutch as i want this truck to be reliable for trips ect, heres some pics of the operation

Yes mate 5th gear upgraded transfer input gear mod, all new synchro's new input shaft various other new gears and things so it should be pretty decent also warranted with my turbo too.
 
What did the gearbox/tcase set yopu back?
