I don't feel any resistance when pressing on the throttle pedal. In stead, when you press a bit on the throttle, like if you were just trying to get the car to roll forward slowly, the throttle would stay where you had it, like a sort of high-idle. Giving it a little blip will allow it to settle down to the 800 RPM.
I looked into the bearing, and it gets cocked in the seat, so I think that's what is happening- you press on the throttle, the looseness on the bearing allows it to get cocked, and it stays where it is.
I don't think you can disassemble that part. It should have been designed better, with a sealed bearing instead of a ball-and-socket arrangement.
