I bet it is a front wheel drive.I don`t think your g/box is kaput but if you look at the other two questions on this page relating to the same problem then that may help you.I have freed off four of these this month alone,whether it is down to the cold/wet weather,who knows but a general oil/lubricate every now and then to the shaft on top of the g/box does help prevent your problem.
