Try having a look at all the ball joints, track rod ends, bushes and check the wheel bearings (maybe could do with a tweak). Mine did the same, it was the wheel bearings.

There is lots of metal in the land rover steering system, so once it starts wobbling it just keeps on shaking.

Release the steering damper and remove both front drag link and rear track rod.

Jack the axle and feel for play in the wheel bearings or swivel hub bearings.

Feel for lots of play in the steering box.

Also squish the steering damper in and out, it should be very firm from the first movement. Any initial play, farting noises or ease of movement and it's pooped.

Hth, sam.

Happened to me, only it was at about 64mph to the dot, turns out it was the pre load on the swivel hub.

Worked a treat after that.

Swivel hub bearings knackered or need adjusting.
