Hi
I have an Alfa GTV and there is a very slight vibration through the steering wheel at speeds over 50 mph
And under heavy braking (sudden braking from say 80-60 mph) this becomes a significant judder.
What should I investigate? Tracking / wheel alignment?
Thanks
Matt

Hi Matt
First of all, have the wheels been balanced recently? If the tyres are half worn, the balance may be out and they may need re-checking. However, the brake judder may point to a bit of suspension wear - top or bottom ball joint would be favourite but a good shaking on an MOT test ramp will reveal all. If the steering shakes while braking, but there's not much vibration from the brake pedal, suspension wear is the most likely. If the brake pedal judders as well, it could be something that's becoming quite a bit more common; brake disc thickness variation. Often diagnosed as warped discs (which it isn't) it's due to uneven wear of the disc. The simple cure is to find a garage with an on-car disc lathe (check this web site for your area:
http://www.skimmydiscs.co.uk/Find%20a%20lathe2.html).
Get them to skim the discs on the car provided they're still comfortably above the minimum wear limit. If they're too worn for skimming, try http://www.brakeparts.co.uk/ for new discs (or get a garage to supply and fit them).
Hope that helps
Tim
