I have a 1996 1.3 Nissan Micra which has had a shaking steering wheel since I bought it a year ago. I have had the wheels balanced half a dozen times at three different places, and also the tracking done, and it is still happening. In fact, from only doing it at around 70 mph it is now doing it from about 30mph upwards since the last balancing this weekend. The place assures me their balancing machine is accurate, and as they are one of three places to do the balancing for me, I am inclined to agree with them that this is not the problem.
They have also assured me that the wheels are not buckled, and that if they were the balance would have sorted the problem out anyway. I have the the wheels swapped from front to back just in case there was a problem, but it hasn't made a difference.
I don't particularly want to spend a load of money on fixing this problem as the car is old and probably one I would want/need to replace in under 24 months anyway, but it is unpleasant to drive and I am also concerned that the cause could be something dangerous. Does anyone have any idea of the most likely cause, and roughly how expensive this would be to repair as I don't want to spend a fortune on speculative investigation which obviously the garage would like me to do!!
Thank you
