Steering wheel wobble, Disco 1

Hi folks, I have a Disco 1, 1992 200 TDi, with a 2" lift.

I was out green laning with Muddy Gonzo and the others all last weekend, and towards the end of sunday, the steering wheel developed an on/off "wobble". It's not at any particular speed, occurs randomly at anything from 25 MPH to 70 MPH. I had a noisy bearing too, and put it down to that, but after changing the bearing today, the noise has gone but the wobble is still there.

The wobble will stop if change pace, so either "power through" or brake. It persists for a few seconds each time when you change speed. I'm really perplexed and have no idea what it could be!! My next suspicion is either steering box or a dodgy CV joint... If it was a tyre/ wheel balancing issue then surely it would be at a certain speed?

Any thoughts?

Would check wheel balancing and steering damper, have just gone back to my road tyres from muds and it has made one hell of a difference

check all your bushes, bearings and swivels

try the swivel pin pre-load,had the same with mine,ajusted pre-load and cured it.

If none of the above work, try lookin' towards yer steerin' pump. Although ah'd check the track rods ends furst
