So just to get my head around this, the transfer box wears it self out by rattling loads. The video shows a really simple fix if you catch the problem in time. Surly this part would be covered by life time warranty if you still in it. If not surly VX has a responsibility to say its their fault and will help with the cost. If later on the transfer box develops a hole then its got to be faulty product.
GM seem to try and cut corners and i seems to bit them in the backside.
How do you know your transfer box is on the blink as you could say?
