New wheels causing a slight problem...
Right, before I start, let me just say, that I am a complete n00b when it comes to things like maintainence, etc. But here goes...
Since I got my new wheels last week, while driving in a sraight line, I notice that the steering wheel shimmys a little bit every so often - sometimes to the left, and sometimes to the right. Its not noticeable to the passengers - but I can feel it in the steering, even though its not hard to just hold it straight.
I increased the tire pressure up to 38 psi on the rears and 36psi on the fronts, and the problem is (almost) gone, but I can still feel it abit.
I took my car back to the garage where I bought the wheels from, and they say that my bushes and shocks need to be replaced. But I wasn't too convinced. They came to this conclusion by raising the car, and wedging the arms with some sort of tool which looks like a crow-bar. This made the arms move around a bit, and they said it should be rigid. But i was like wtf? if u take a crowbar to it, of course its gona move like that. Like I said I aint no car expert, but I was able to analyze his behaviour, and I think he's bullshitting me.
Anyway, I spoke to another mechanic on the phone, and he said that the new wheels are heavier, and I need to get stronger wishbone ball joints - the ones from the sports suspension.
I spoke to yet another person, and they said that the wheels should go on without any other parts needing to be changed.
I've done 80K miles.
I hope its something like a wheel aligment issue, which won't cost as much to fix.
