The faint clicking is normally, it does that by design. That is the noise of the inner gears ratcheting and allowing it to turn without binding.
If it is bucking, let off the throttle some. It shouldn't be bucking while turning if you are off the throttle, unless your tires are very very worn. The traction of the tires should overcome the locker actually locking if you're coasting.
It should function the same turning left or right.
