At about 60 mph my car starts shaking. REALLY BAD. I've had the tires rotated and balanced, and the vibration persists. Furthermore, after going autocrossing the vibration was way worse (but then got slightly better), so I'm going to guess it's a wheel hub. Is this something you'd recommend I do on my own to save a few bucks? I would need to buy a torque wrench and source a new hub or bearing or whatever, but I'd rather not make my dad have to pay a shop for something this small.
