Gearbox problem?

Forum: 

Help!
I've recently bought an R reg Fourtrack Independent. It seemed ok on the test drive, but since using it in 4WD this weekend, it wont come out of it. With the selector in 2WD and the dash button off, it still registers the electric 4wd light and won't disengage from 4wd. The steering is very heavy, pulling to the n/s and I dare not go above 20mph because it makes a nasty noise. When I stopped, there was a hot smell from the front of the truck.
Any ideas.
Thanks.
Russ.
