No drive to front wheels ?

[steveb]

She's been in the car doctors lately to have a front diff replaced as well as a new offside front drive shaft......

Now even with the new parts, still no drive at all to the front wheels ?

Took her into a muddy field .. foot down ... rears were spinning for a short time then power seemed to drop to the rear wheels ?
NOTHING happening from the front !

So to me, the transfer box was cut power to the rears but did not transfer any to the front ?
I tried this with and without 'DSC' - same result ?

Any help mucho thanks
