Adam F, I'll try your suggestions. There's no uneven wear on the tires because they're new. The old ones seemed to be pretty evenly worn as well.

In the FSM, there's one picture showing a person's shoe on the tire while the front wheel is off the ground, using a lever on the lower suspension arm I guess. Then, there's another picture showing a lever lifting up the tire, with a block of wood as a fulcrum. Tomorrow, I'll see if I can try to do whatever it is those two pictures are supposed to show.

I don't think there's any grinding noise, so I guess the bearings are okay. I still would like to check them since they're about due to be repacked with grease.
