I HAVE JUST FOUND OUT THAT THE FOUR WHEEL DRIVE IS NOT WORKING.
1997 Isuzu Bighorn

There have been bangs or grinding noises from the front. It is unknown how long it has been like this as it is not used often, We've had the vehicle for about four years and the four wheel drive got used a couple of times then not at all. It has bben suggested that there is vacuum involvement in the selection/engagement of the drive? What are the likely causes? What are the easy quick things to check first?
