Thanx for the reply.
This is a safari van all wheel drive.
The front wheels are in neutral until the back wheels turn a fraction faster than the front wheels. This happens automatically. Or is supposed to.
When the drive shaft to the front wheels is diconnected, the diff acts as normal. When the front drive shaft is connected, the van remains in 4 wheel drive all the time. This should not as per above paragraph.
I suspect that the problem is electrical or electronic but don't know where to start looking. Neither does anyone in Winnipeg, Canada.
