disco only moves wen difflock engaged

[manta]

hi all,
        bit of a newb at this but here goes.
      disco auto 95 n reg.    drivin along  accelerate bit of a  bang, loss of drive, no drive at all in high or low range unless difflock is engaged.
      if diff engaged she drives perfectly thru all gears, but obv i cant keep her in diff all the time, ne one ne ideas  wats wrong. diff trans or gearbox????

First things first. Jack it up so all wheels are off the deck and then engage drive, with diff lock in...... See what wheels go round......

Sounds like you've done a diff in.

could be a diff, but could just a halfshaft...

You'll know what's what by following the step above  :lol:

i.e. two wheels going round (same axle), diff

Three wheels going round....., half shaft.....

could be a diff, could b a halfshaft, could be drive flange stripped
could be a blown cv

jack 1 front up and 1 rear, stick in difflock and see which end will rotate, that will tell you if its a front or rear end problem

What i did to find out which end the problem was, was to disengage difflock, engage first gear with hand brake on, then lift the clutch, and get a mate to glance underneath to see which prop is turning, thats the end with the problem!!

I stress that i would NEVER advise actually getting underneath, as things can jam up and could potentially make the truck move!!
