My grandson is complaining of steering wander in his 1996 Cavalier. He has studded winter tyres installed that were balanced at installation a month or so ago, pressure doesn't seem to be a problem and is same on both sides. I drove the car myself and must say that he was right - the car is all over the place - it is icy on the road at the moment in our locale and I am used to driving my CRV but even so - I was quite nervous. Where would you suggest I start to look. Incidentally, a couple of months ago he put the car in a ditch and he assures me that the steering wheel was straight and level before but is no longer. Is it possible that something let go underneath, I don't see anything obvious. Will an alignment put this right ?
