Last update, there is no other option but to remove the rubber piece and the duct tape won't also fit technically 100% because the drive shaft is not completely fitting in the chassis that is why the rubber part is curved towards the tire, picture attached to show the rubbing with tire and wheel part
I eliminated the sticky part on the duct tape just incase and added lubricant on the drive shaft so it is isolated and that is the best solution we could reach after all the brainstorm to minimize the dust from entering to the drive shaft moving parts inside.
