vibration in front end when accelerating starting at 40 mph - 60 mph

Thanks. i have appt at 1:00 today. Mechanic on phone said it sounded like maybe drive train or motor mount problem. He said if vibration before AND after putting new tires, balancing & alignment it wasn't an alignment / tire problem.

Well at least it seems the mechanic possesses some logic! Many do not... Good luck with it!

Thanks
