I had a shaking problem shortly after i got my svx. It was not a constent problem but seemed to aoccur at random times when driving at roughly 60 mph or more. It turned out to be a faulty front passenger side caliper. One of the pistons on the caliper was sticking which caused it to "drag" against the rotor at times, this caused the shake. Just something to think about.
