Hi Guys,
First post, great - what a downer. I've been having steering vibration on and off for 2 years in my 2009 Saab 9-3 TTID, originally it was blamed on the Continental tyres (225/45/18), then I swapped all for for Michelin PS2's and all was good for a year, then I replaced with Michelin Pilot Super sport and was getting a very slight vibration over 70mph, which I lived with. Now this weekend, I've swapped my tyres over to Continental TS830p (215/55/16), I had all 4 wheels balanced and they were fine, this morning I've been getting random steering vibration over 60mph, on some roads it is perfect without a problem, on most it was really quiet annoying. The other thing to bear in mind is, in the last 12 months my front brake discs have been replaced twice, garages blaming the problem on the n/s disc being warped. I've also been getting random steering vibration when braking from high speeds. I've had everything checked, suspension, calipers the lot, 2 garages say nothing is wrong. I've had the alignment checked last week and garage said it was fine.
Can anybody help please? I'm at my wits end, I think I need the on-car balancing done to rule out the balancing.
I live near Chester but am prepared to travel anywhere and pay good money for a quiet life. Otherwise I'm going to ditch the car next year. Thanks guys....
