2. Clicking or Humming
Verify by driving on a smooth surface testing for noise while turning in either direction. Remedy- replace outer CV Joint or complete CV Shaft.
Verify by driving on a smooth surface straight ahead putting load on vehicle. If you detect a vibration or shudder, replace inner CV Joint or complete CV Shaft.
