My Steering column is making a 'TUNG TUNG' sound when its turned either ways. It came up first a month before and disappeared on its own after driving the car for a few kms. Later it reappeared and hasn't reduced yet. I am also getting a vibration on the steering and brake pedal along with this sound. On the outside its tough to find this sound but there is a prominent vibration on the side panels( where the side indicators are placed). There is no other change in the behavior of the steering. There are no noises while going over potholes either. It seems to be associated with steering only. Is this also due to worn out elastic pads? Also whats the approximate cost of this part? My car will be 5 years old this november but with only 30k on the odo.
