Yes, the winch is secured to the mounting plate and then the plate and bumper use the same holes to bolt to the frame. Believe you can't get to the winch nuts and screws until you remove the bolts that go into the frame. Then after you take those out it's just a matter of lifting the winch and mounting plate off since they're together then placing it somewhere you can get under the plate and undo the 4 screws and nuts. I set mine spaced out enough on 2 chairs to put on and off my winch.
