Park your MH level and have a the proper tools. IIRC a 17mm, 19mm and a 13mm(?). You likely won't need to raise vehicle. Loosen the down links at the sway bar. If you can't raise the bar to line up the holes or it is too hard to raise loosen the bushing mounts a little. CAUTION the bar could drop. Refasten the down links to the inter hole. ( To the rear if doing front bar, to the front when doing the rear.) Put some blue Locktite on the bolts, tighten and enjoy your new ride.
