It is definately not a balancing issue or alignment issue because I just had both of those things done twice at different shops, and those shops can't find the problem either. Thanks for all the info. so far I really appreciate, so please keep the help coming, because I don't know to much about the suspension of the Alero. Also if it helps I do have a Eibach Springs lowering kit to, there is no rubbing at all with my wheels in the wheel wells, oh and my wheels are not bent either I had checked those myself and also had the shops check em to. So let me know if you have any more ideas, thanks guys!

My brother had this problem with his truck, vibration at highway speeds, he had the tires balenced several times all at different shops, had it aligned a couple times but it didn't go away. I gave him my old mud tires from my truck and the vibration went away, so we concluded that one of the tires were out of round.
