DEFENDER 110 SHUDDER AT SPEED

Best to get the swivel pre-load checked, until mine was sorted I had similar troubles.

Swivel preload is the usual suspect for this symptom, but there should not be ANY play in the tie rod ends, and play here or any of the suspension bushes will encourage the oscillation once it starts. JD

so we're talking a crater roughly the size of Norfolk then?

To ease the problem temporarily, and I stress temporarily until the exact cause is known, try lowering the front tyre pressures. On my Disco it disappeared at 28 psi. I never got to the bottom of my wobble. I had springs, shocks tracking and balancing done, changed the discs, wheel bearings and pads too. Had the preloads checked and the steering joints - all said to be normal. Tyres are wearing normally. Found a little play in the steering column and changed that too. Having done all that and reduced tyre pressures the wobble all but disappeared. I have just put the pressures back up again and the wobble has re-appeared on big holes only which I can just about live with.

well Coochiemudlo at least!

Try this.......

Or even this........

Thanks to all who replied. I now have a short-list of things to look for. Interestingly, nobody mentioned the radius arm bushes, yet this was presented to me as the most likely cause by my LR specialist! I guess that it is now a process of elimination.

Thanks again for your help.

Radius arm bushes are very unlikely to cause it, but will exacerbate it. These were covered by my "any of the suspension bushes", but they are not particularly a problem. In fact the panhard rod bushes are more likely to increase the vibration than the radius arm bushes, and inboth cases the primary effect will be wandering steering rather than shudder. JD

Hi Scott,

Had a similar problem with a 1996, 110 Defender. We tried all of the above fixes with no luck. As fate would have it there was a problem with the front diff and out she came for a rebuild, problem solved, no more shudder when hitting bumps.

Hope this helps.

Hymie uttered summat worrerz funny about:

Also swivel pins IMO the most likely cause as they all do that sir , do a google, we've done this to death many times here :-)
