I installed the lift myself and I think the fact I had never done anything that extensive myself rattled me a bit. I did my homework before taking it on, it still took me 15 hrs. but I got through it. Went over eveything last night in my garage again and noticed my Sway Bar end links were a little loose. Tightened 'em down and no noise what so ever. I will check them again in a week but if they do seem to come loose, even with the use of a nylon nut, can a guy use loctite like on the axle spacer nuts or not????
