I know this is an old thread, just wondering if anyone could help me out to pinpoint the most probable cause.

Over the summer, this suv tipped my front left bumper going 70 on the parkway, i went to the right and overcompensated turning the wheel to the left and i spun doing a 540 on a dry bridge. (this was a hour b4 rush hour - I saw 2 cars veer out of my way going 70 [almost crapped my pants])

Neway...wheels seem to be ok, I just had new tires and an alighment done. Steering wheel still vibrates at 65+. Dont really want to spend on coilovers, I like the ride the way it is and dont really have soo much money to spend.

And does anyone know wheres a good place to get this checked? Other than the typical gas station garage?
