gromero: were both your cars cold when you did this test? I find my vibration naturally dissipates after about 10 minutes of operation then return about 30 minutes later. (caused me to blame tire pressure for awhile, not the case.)
This "on tire" balancing is sort of cheating (cause is not eliminated, just balanced out) but my local dealer has "road force" balancing which I'm told eliminates vibration other balancers won't, so I'll probably give that a try before I spend money on diagnosing my entire suspension/steering systems.
I'm glad we've got a support group going for this. No local dealer has ever heard of it but they promise they can fix it. Maybe I'll get one of them to sign it in writing and hand it over.
