We spun two nutserts installing on the WK in the exact same spot on both sides of the Jeep. I think its the shape of the body in that location that does two things. First it's a little harder to get the nutsert to sit and grab flush. Second the angle at which the bolt must enter threw the slider to the nutsert is a hard to achieve as well. This is really no big deal and easy to fix you could just tack the nutsert in place if you can. I just drilled out the nutsert and put a new one its place. So sending at least one or two extra serts with purchase is a good idea especially for the WK guys.
