I have a 5th gen lude and sometimes when i break at high speeds (damn traffic lights turning yellow and damn photo enforced intersections) i hear this moaning sound, its quite distinct. Could it be the abs kicking in? And when i idle in traffic going lesss than 5 mph, and i hit the breakes, i hear this click/clack. Is this something i should be concerned about? And theres one more thing when i turn my steering wheel all the way in one direction, and turn it back to its center, i hear that distinct moaning sound too...whats causing all this?

These sounds do happen quite frequently by the way
If anyone could helpme, thanks in advance....
