Jack one wheel up, check for lash in the transmision. Could be stuck in difflock.

drop the oil out of the axle
but  :shock:
last time this happend to me, wasnt the diff, wasnt the hand break altho everything pointed to it, was the rear output shaft bearing in transfer box had collapsed and welded itself together, would drive 2 ft before locking up, drive backwards abit lock up then just locked up altogether and wouldnt budge, had to drag it off the road with my 90's winch  :shock:

btw, when i diff goes, it usualy just spits its guts out of the axle casing, so i cant see it being that, handbreak or a bearing somewhere id say

does it clock and nock its bag off ?
chock the wheel
let hand break off and take it out of gear
scraw underneath and turn the rear prop and see if its notchy
the grab where the prop bolts to the diff and check to see if the pinion bearings aint collapsed
and then feed back
thin brown mess says to me its not been changed for a while, and its got abit of muddy crappy water in there

if was something to do with transfer box would it still do it in neutral on transfer box as that didnt make a difference

If the oil is clear oil colour (as new) - very good.

Browny colour - worth changing.

Milky - water has got in and change oil needed.

Black mess - needs changing.

If it feels gritty to the touch I would worry mate. Thats as far as my knowledge goes im afraid.
