Tried the radio station change. Didn't work

. I believe it may be the offside driveshaft as the whole front of the car seems to wobble from 40mph up to 50mph and then clears. I also have a split boot. I am still half hoping maybe the front wheels need balancing but it probably will be the driveshaft. In my experience wheels out of balance shake the car at higher speeds, the symptom I have is more of a side to side wobble. I believe there is a bearing that the driveshaft runs in half way along, presumably it is advisable to change that aswell? Thanks.
