can anyone help? brought the DCF-886 impact driver about 12 months ago and stupidly forgot to register the tool on my dewalt account for the warranty. recently when I try to put a bit in the impact driver it does not click in and hold the bit so it always falls. I was wondering if anyone has experienced this problem and how they resolved it? ive seen that you can buy replacement parts online but im not sure what component I am looking for any help would be appreciated
