Severe steering vibration

Steering damper first, remove to check or misshapen front tyres.

Lack of swivel bearing preload.

My money is on this too. Had the same on a RRC.

Or a knock off-road has bent the track rod, nocking the tracking severely out? Had that on a racer once, similar wobble. Badger.

A thought, but I don't do much off roading in this one and certainly not recently. The worst it does is the byeways on Salisbury Plain!

First thing tomorrow I will swap front tyres for rears. If that has no effect I will remove the propshafts one at a time, if that fails I'll check the pre-load on the swivels.

It looks like that the vibration was being absorbed by other components in the system (panhard and drop arm) and when those were brought back into spec. there is no longer any absorption for them in the system.

The joys of owning a LR!

Front to rear wheel swap and the vibration has gone!

Easy as that - at least it's got new panhard bushes and a much tighter drop arm as well!

No obvious defects on the rims or tyres. At some point I'll drop the car down to my local tyre place and get them to check the balance.

well, speaking as one who has on and off being trying to cure a RRC of shimmy-of-death disease, I reckon it'll be all of 'em.

On mine, steering damper made most difference despite apparently being functional, but swivel preload also made a difference, and it's still a bit prone on hitting bumps.

On what is now your Clumber Spaniel Wagon, I had a really violent shimmy triggered by bumps and that was cured completely by replacing a totally fscked damper - it had literally no damping effect at all.

crappy tyres also had an effect on the RRC: puttign decent, matched ones on made it better but didn't cure it. As I say, it's still a bit prone but then again I replaced the steering damper with a second-hand one which was in better nick, not a new one; might be that a new one would sort it out properly.

If none of the cheap solutions given seem to work then change the shocks and the steering column. A tiny amount of play in the column can cause the symptoms you describe, it's easy and fairly cheap to change too. TonyB

done that already, it had slight wear and made it a bit better. Haven't done bushes, but they don't fail the MOT so I assume no huge play in them.

Well, on the advice of a neighbour I removed the brand new LR Panhard bushes and fitted blue polybushes.

A darn site easier to fit and with 200 miles under my belt now, no sign of vibration at any speed!

Happy bunny.

Now off to Beijing for a fortnight!

Thanks for all the advice.

Thats a long drive in a LR !... But the food's good when you get there..
