I have been pulling tree roots and small stumps with the winch. On four different occasions, the front left lug nuts have come loose. I have re-torqued them every time to 130-140 ft/lb, but still they have come loose again. I park the truck on my paved driveway, tranny in park, t-case in four low, and parking brake on. Twice, the winch pulled the truck toward the stump. As I said before, I did re-torque them after I finished. The next day; same issue after winching. If you winch, keep an eye on this.
