Very Bad Steering Vibration

[Cadbury]

Hi all,
I hope someone can help.
I have developed a very bad steering vibration . It happens when driving at about 60km/h and more and going over a bump. The steering shakes like mad and the only thing to stop it is slowing down to about 15km/h.
Any ideas?

Hey mate - have you checked bushes/rubbers on panhards, leading arms, swaybars, steering arm etc? Thrown any weights off the rims (with all this rain/potholes everywhere, it's possible)?

Hi Bigrig,
I had the leading arm bushes replaced when I did the lift to correct the caster.
I will go get alignment done today. Maybe thye will be able to tell me if its the wheel bearings or the tie rod ends.

Good luck with it mate - let us know the culprit once identified!!

Sounds like panhard rod bushes to me.

The wheel and tyre place said its my steering damper that is leaking. Does this sound right?

[Bigrig]

I didn't think that would account for a "wobble" at speed (Tony??) - understand if the damper is shot it could be harsh through the steering, but haven't got a clue about causing a wobble as such ...

Steering damper won't cause a wobble, but a good damper will help mask a wobble caused by something else.
If the damper is leaking, replace it. But it won't fix the wobble.

As Tony has stated sounds like Panhard. Unless the wheel bearings are dangerously loose or shagged all you will get from them is a shimmy. Just replaced the panhard in my brothers GQ as one of the rodends were stuffed. He now has an adjustable. The advantage of the adjustable is you can replace the rodends instead of the complete unit.

Are you talking about the panhard or drag link? Panhards have bushes not rod ends.
