The compression spring is part of the impact drivers chuck assembly. The spring is found over the anvil shaft and provides tension to pull the chuck collar back after a bit is removed. Over time this part can lose tension or become damaged. A failed compression spring will cause the collar to move freely, and the driver bit will come loose. This is an OEM official part and is sold individually.
