The wheel problem solves it by forcing the sensor holder towards the inner side, very carefully. So the wheel fits better and does not make the rebound error any more.
First, two screws are removed under the bottom slider.
Then remove the upper housing, remove four more screws and release the lower housing.
Turn the wheel plate and remove the wheel. We clean and very carefully force the sensor holder in, very little.
The wheel is placed and the plate is returned to its place. Without assembling it is proved. It is repeated if it still makes the mistake. It is assembled following the reverse steps.
