I should preface this with saying that the 850 is running Bilsteins(all the way around)/TME lowering springs/Voxx 17" wheels/Micheln 215/45/17s/IPD strut brace/Volvo camber kit. <p>My father is feeling a light vibration in the steering wheel when he is traveling over 65mph on concrete-on asphalt he is says he can't feel the vibration. After assuring me that he didn't think the vibration was coming from the stiffened springs/bigger wheels/less tire rubber(as compared to the stock tire) absorbing energy, I went to work(with my mechanic) trying to ascertain what the issue could be. Both end links were replaced, the shock/strut mounts were checked, the tie rod ends are less than 2 years old, the wheel bearings are good, and everything in the suspension seems nice and tight. <p>The car was in for an alignment less then 1k ago, and at the time had all the wheels balanced. When I was washing the car a few days back I noticed that the weights had come off the front passenger wheel, so back I went to Big O', and ten minutes later the wheel was balanced(w/ new weights). Any help would be most appreciated. Thanks!
