I have an 86' 190E that always pulls to the right. I have checked the brakes on that side and found no problems. Also I do not see anything wrong with the front suspension components. However on the right rear the "pulling" strut's (or control arm) rubber mount is damaged. Could this be the reason for the car to pull to the right?

I am not sure if that strut is called a control arm or a pulling strut. According to the Mithcell serice manual, they refer to it as a pulling strut and say the whole strut has to be replaced if the rubber mount is damaged.
