If that doesn't fix it, it could be a worn thrust arm bushing (the rearward of the two front suspension arms). Quote Share this post Link to post Share on other sites
zenetti 0 Report post Posted April 17, 2008 If the wheels are not hub centric you will DEFINITELY need centre bore locating (CBL) rings. Most european cars are notorious for the 'shakes' you describe if the wheel is not located centrally on the hub. Kiwi535 had the same problem a while ago and teh rings solved it. I highly doubt it will be a bent wheel as this would have shown up when when the new tyres were fitted. PM me for more details if you want. Quote Share this post Link to post Share on other sites
