Hi,

It never happened to me before but for some reason my steering wheel shakes between 140km/h and 160km/h only. I have had a balancing done at least three time in three different places and no one can find any problems. The front tyres went to the back and back to the front. I still can notice shakes. I was told to go and to a road force wheel balancing. I can not find any place around London doing this. Can anyone heard of a good place to have it done.

Many thanks

Yaro

errr don't drive so fast, presumably this is only a problem on your private air strip.

Did it get better when the tyres were swapped round? Could it be a suspension problem perhaps?

Well with vRS it is difficult do drive slowly unless you got stuck in a traffic.

When the tyre were swapped around I still could notice shakes. Suspension wise they could not find any problems. Recently upgraded springs to H&R, Koni shocks, bushes in order etc

Very strange to me

Are there any more suggestions? It still does it!

I had a similar problem on my previous car after having new front tyres fitted. I went to a couple of places to get the wheels rebalanced to no effect.

It was because the tyre fitter had lost one of the wheel studs so he "borrowed" one from a rear wheel. The garage that found the problem was so incensed he obtained the correct part and fitted it for no charge!

Check you have all your wheel studs/bolts/nuts as appropriate.

This is goign to sound well odd, but one of my mates once had to track down a rumble that only appeared after the car in question had 2 new tyres fitted. After much normal diagnostics, shuffling tyres, runs up the road with 3 additional sets of calbrated ears, we decided the rumble was actuallly following one of the new tyres, demounted it, and won a set ot 10" electicians pliers!

If you have had balancing done on all 4, my money is on the tracking.

Toe will be out on fronts.

the fact that you can drive through the shaking suggests to me that either you have a faulty tyre or a damaged wheel or a worn steering/suspension component,have you had the wheels re balanced? its not un common for wheels to be balanced incorrectly sometimes! tracking wont cause your wheels to shake,it only effects tyre wear & steering alignment.

My L&K suffers from this aswell, only at higher speeds is it noticable. No suspension mods at all... Yet

All wheels were balanced 3 times. I have some time tomorrow so go to a frend to look at it. Thank you very much for all your comments.

Cheers.

I shall be in touch

Find a friend and swap all 4 wheels over to your car.

You could have one or more out of round tyre, this can be balanced out on a standard balancing machine and for normal driving you will not notice it. However if you drive fast then it becomes noticable.

I would try the previous posters suggestion if you can. Borrowing a set of wheels to see if the problem goes will at least elliminate the car from the problem, or not.

See my thread "cured-rattling-etc" as mine used to do this and doesnt anymore. I'm not 100% sure what cured it but I think new wishbones and bottom ball joints were most likely. Good luck;)

I have had the balance done on fronts again and there were 5g on passanger's side and 15g on driver's one. Toe (passanger's side) was out a bit. Front tyres Continental3 new set... steering wheel still shakes at around 140km/h. I have had wishbone bushes replaced 3 months ago (Super-Pro). I did not do the ball joints... hmm worth checking ... till later

many thanks

Check the runout on the hubs.

when I first fitted my 17"'s I used to have problems. Took them to tyre fitter and had 1 tyre replaced and all four balanced (before fitting in place of 16"'s) and the tracking adjusted, but still had vibration at speed. Went back to the tyre fitters after doing some research and advised they use the "small cone" instead of the normal one and when he rebalanced it was 35-40G out on two of them and 15-20 on the others, so he redid them all and has been fine (up until last week when I hit a drive a bit hard so need to get the tracking done again)

I am sorry but I am not familiar with 'runout of the hubs'. Could you please be more clear on this. Thanks mart

Also I do not exactly know what what do you mean by 'small cone'. Thanks karlbar

Runout - If you spin an onject on a fixed axle, it should remain in a fixed reference plane relative to the axle. In reality there are probably small variations. These are the runout. For more information on the subject start at Geometric dimensioning and tolerancing - Wikipedia, the free encyclopedia

Small cone - Wheels are clamped onto balancing machines using a flat plate and a cone through the wheel centre. The small cone is exactly that; the smallest of the set of clamping cones the machine comes with.

In another garage they said that driver's wheel is recline towards inside hence vibrations at high speeds.

Could this be anything to do with the brake discs?

I'm not sure what you mean by this. If you mean what I think you mean, that the wheel's not centred in the straight ahead, then that probably means someone's done a poor job of adjusting the tracking by taking all the adjustment on one rod end.

Could this be anything to do with the brake discs?

Not as such, but if the discs have been replaced recently, then a little grit on the disc to hub mating face could be a source of runout (qv) at the wheels. I'd expect you to have a long brake pedal if this is the case though.

The discs were replaced fairly recently, yes. The job was done properly, I would say. I have EBC brake discs and red pads. I noticed that if I push the break on , sort of heavly (at high speed - 90mph) than the steering wheel shakes a little bit. If I am taping everything is fine. I was driving today on a motorway at 90-100 mph and it seems that the vibrations at those speeds have settled. I can not explain it. I shall keep my eye on it. But breaking from high speeds causes the steering wheel to vibrates a little bit. I just wonder what else is going to happen.

A run-out check would confirm it, but I honestly now think the most likely problem is grit on a disc mounting face.

Ken I had something similar happening with mine. Turned out to be the cv joints out of balance and kinda munched.

It may be your diff starting to go!

Cheers for ths info Fugs, cos I've never encountered that happening before, but I always prefer to start with cheap options and work towards expensive unless I know the expensive one is right.

Well its obviouslt something in your drive train thats out of balance. Does the car still do it if you coast in Neutral?
