hi everyone, i was driving today, and when i got to around 70 mph +, the steering wheel bagan to vibrate, not a great deal but enough to notice......it has never happened before, any ideas??
 
As above... if you dont get it until 70mph and if you can drive through it then wheel balancing would be my first port of call.
 
Unblanaced wheels can make a huge difference to the pleasure of driving a car - it ruins it!

I have come to regard proper balancing of wheels as something of a black art of late. I got the front wheels on my S2 rebalanced for the fourth time a couple of months ago - by the same place that did them on times 1, 2 and 3. This time they actually got it right (had they not managed it, it would have been back for a 5th time ... and the only reason I went there was because they were highly recommended by several people ... )

On a different car... My Focus was vibrating and I got the front wheels done.. Not much difference... I decided a few days later to get the back wheels done.. I was asked "Why are you doing this...?" The boys done it and that cured the shimmy.. From now on it will be all 4 I get done.[;)]
 
I always also fit the locking wheel nut opposite the valve, it helps eliminate vibration as the wheels are always balanced OFF the car.
 
Well this wheel vibration caused me much trouble with my previous 944 and the one I have just purchased is doing something similar.( though I have yet to try and attempt balance of wheels)

I had my previous porsche balanced countless times to make no difference at all really in terms of being acceptable. eventually I remembered my days fitting on trucks which had their wheels balanced whilst fitted to the hub or simply on the vehicle.

Hardly any will have such a machine these days but there are still some around.

Balancing on the hub takes away any influencial causes of vibration from the hub and strut etc. the result was much much better. if all else fails then this is a good option as your vibrations may be caused by other stuff. You just need to remember to put the wheel on the same way you take it off to avoid those wobbles coming back.

I hope this helps as at the time I was having these troubles I felt just like the previous comment and it was spoiling the pleasure of ownership.

cheers

I've seen adverts for wheel balancing on the car, but was never convinced by them. The effect of an off-centre weight will be a product of the distance from the centre of rotation, and given that the wheel is the biggest thing that rotates (driveshafts etc are all small diameter by comparison), I was dubious as to how much difference it would make.

Therefore, I'd interesting to hear something positive about it as an idea. Thanks Paul.
