Death Wobble 2000 Range Rover

[Rjhaworth]

I have loved my rover even with all of the problems. First was the air suspension, swapped it for a coil conversion. Second now is that I still have a death wobble at 55 -60 MPH. I have replaced the steering dampener and have has tires balanced and rotated and also replaced the panhard bar. I would get a vibration at about 55-60 then it would go away at higher speeds. If I power through 55 like when getting on the freeway no vibration. I have had a couple of times when I hit a small bump at speed and I get wobble in the front but goes away if I just let off of the gas for a moment. Last week I was driving on a smooth surface and wham, bad wobble. Scared me pretty good as it did not go away quickly, in fact I had to slow and pull to the side of the road before it would go away. Felt like the front end was shaking apart. Did it twice in row once I got up to speed again. Nursed it home at speeds below 50. Could it be the bushings on the torsion bars up front? I have read about some sort of pins, are these similar to a ball joint?
Any help would be greatly appreciated.

So, how many miles on it, have you checked and replaced all the bushings and or tie rod ends?

156000, and I was hoping to get away from throwing parts at it. I have had it to a couple of tire/suspension shops and they cannot see anything worn or loose. I will be taking it to a land rover mechanic tomorrow, hope they can find the issue without trial and error.
Thanks,

So here is what I have summized. My Rover is a 2000 with 2003 wheels. The centering ring is not an exact fit and the has caused the wheels not to center and I believe has been causing the problem. I used a hose clamp(sans the clamp part) and was able to fill in the open space between the centering ring and the wheel on all 4 wheels. This improved the bounce tremendously. I am having some made special at a Tech College that has a machining class.

You may also want to replace the top and bottom swivel bushes/bearings on the front hubs. This can cause a bad wobble, but to be apparant when you jack the wheel off the ground.
