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.

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 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

Post by: Disco-Ron on June 12, 2007, 23:09:39: 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!!
