Transfer box has be known to go although usually diff first, regular fluid changes normally keeps them going. Are your ayc lights on by any chance?

No there should be a AYC light on te dash if it's lit you may have a problem at the back

Not on a 7/8/9 mate. It's ACD with 3 lights on the dash Tarmac gravel snow.
If all 3 lights stay on then Ayc/acd isn't working and there is a fault.

 

[discodave3]

yes all 3 lights are on they have been on for a while when the car is stationry you can switch them but when you are driving they all come on and you cant switch between them thanks dave

You need to check the fault code. You can do this by using a small piece of wire and bridging pins 1 &4 on the obd port under steering column. Once you done this turn ignition on and count the fast and slow light flashes from the acd lights
