The bushing in the steering shaft and the gear that go thought he frame to the steering linkage are bad and need to be replaced. The problem is the gear at the bottom of shaft or the steer wheel don't want to come off. It looks like some sort of cap washer holding the steering wheel on so I can't pull the wheel off. I can't get to the shaft to pull it. Also I didn't want to break anything either. Please help,thanks.
