    This will be short and simple. Prices, videos, and parts are on point. If you have tools not working properly a part that needs replacing. This is the place to look Thanks again. I Recommend. E Replacement Parts
    Brian - August 11, 2022 Verified Purchase
    Great part-difficult repair.
    The part was correct, it arrived quickly and the whole transaction with Ereplacementparts was quite satisfactory. However, be aware that the Youtube videos that show you how to replace this spring in a Dewalt Impact Driver make it seem like it is a simple fix. IT IS NOT! Got it done, and the drive works correctly, but it was an ordeal, and I am pretty handy at fixing things.

    Watched your video for this repair and it made it very easy to do. Watch for flying parts as you remove split ring . It's little hard to get split ring started back on. Here is a copy of the video
