If you don't know about the brakes on your new classic Z and it has a wobble in the steering wheel around 30 mph then you should try this. I replaced the inner and outer front wheel bearings, had the rotors turned and new grease packed in the hub. $50 to go from driving what felt liked a cooked spaghetti noodle to an uncooked noodle, stiffer without the shakes.

Here's the info;

Good stuff. If you get your rotors turned, be sure to leave the hub attached to the rotor while it gets turned. Otherwise, you might get a pulsation in the brake pedal since its not a free floating rotor.
