Defende8r death wobble

Hi I need your help. I have a defender 300tdi and it has developed a terrible death wobble at 50mph. I last night drove up a curb slowly to get through a tight spot and the death wobble disappeared for about 5 miles before returning. Just before it starts to wobble the front end appears to become light on the steering. I am getting married in the next to weeks and was planning to use the landrover for the special day. Any help will be greatfully received.king regards

Sorry only started today.

Take this to the Defender section. Saying that I'd be careful driving it like that it sounds like something bad in the steering system- serious wear.
