WTF my car shakes at 60mph!!!! Options

[mrgrape]

k so recently i put my car up on the lift during auto tech in high school to
identify front and back suspension and check brakes
after that i rotated my tires and put the tires back on
accidently i torque wrenched one too much
after up on the lift, when i go to 60mph my car starts shaking like it does normally at 90MPH
so im like **** and only drivee 50 mph on freeway thus getting honked or stared at....
whats the problem????
is it b/c of tires or something else?

^ I think you should take it back and tell them about the shaking. It sounds to me like the wheels aren't balanced properly. If your rear tie rods were, well, less than perfect, wouldn't it cause suspension issues and uneven tire wear? I don't think it would cause shaking. That would be more of a front tie-rod or a control arm bushing? Not sure...
