It sounds like your 4WD front locking hubs maybe sticking on. These were automatic locking hubs for this model. Ensure your out of 4WD and then just quickly reverse for a short distance the quickly go forward for a short distance. Repeat this 2 - 3 times, this should disengage the hubs. If the noise persist you will have to get them removed and lubricated again. Hope this helps, let me know how you get on.
