DEFENDER 110 SHUDDER AT SPEED

My 300tdi 110 wagon had developed a shudder in the steering that occurs at
around 105km/h. At lower speeds there is no hint of the problem.

The shudder starts when I hit a smallish (well smallish for Australian
highways) bump in the road and it rattles the steering wheel very
uncomfortably until I reduce speed. I have replaced all the dampers,
including the steering damper, and it has made no difference.

All wheels have been balanced and the alignment has been checked.

It has been suggested that it may be the radius arm bushes, or the pitman
arm. The steering tie-rod ends are slightly worn, but not flogged out.

Has anyone had a similar problem, and if so do you have any suggestions
regarding the cause?

Any assistance will be appreciated.

Regards

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.

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.

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.

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.

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 :)
