Hi all i hope this is in the correct place.

my 90 has developed a problem. When pulling off there is almost a resistance in the drive train as if two gears are not quite meshing properly and are then slipping past one another. It is that bad, that if you move say one yard, until is almost makes the banging noise, it will actually rock the vehicle backward say a half a foot (i think this is the torsion in the halfshafts shafts) If you accelerate upto around 15 MPH (this is as fast as i dare go with such an issue) these 'bangs' become so constant it sounds like a grinding noise. Obviously the quicker you move the quicker the banging noise will get.

any help would be massively appreciated.

As a side note, this weekend i drove it 40 miles did 2 days of winch challenging and then drove 40 miles home and it performed faultlessly. I parked it up for around 20 minutes while i had tea then went back outside and went to move the vehicle and this fault had developed???

Any ideas?

cheers

Just a thought but check that nothing is fouling your handbrake drum (or its not stuck on) and that everything is intact and clean inside too, with a handbrake partially on will give the same/similar symptoms you are describing.
But failing that disconnect (one after another) the front and rear propshaft with difflock engaged and see if the problem is still there, if it has got anything to do with the front or rear axel it will point you in the correct direction. I don't see how you can drive that distance without any problems then suddenly its goosed!

I think you're quite likely right about the hand brake D.G.F.S. The friction material may have parted from the shoe, does it wind up in reverse??
