Had to flatten 2 of the washers with the bench grinder to get them to lay flat and marked that side of the D bracket with a paint pen so when installed I would know and put that side on the bottom. Pregreased both sides of the end links and rubber hourglass bushing and pressed them in the end links with a shop press, then pregreased the O.D. of the steel bushings and pressed them into the I.D. of the rubber hourglass bushings with a shop press.
The only thing that I wish would be different in the kit would be the bushings in the top of the end links, you have to use the stock bolt there, no choice and the steel bushing for the rubber hourglass bushing is for the bolts they send with the kit and there is play there with the stock bolts. May have to look at that area later, may become an issue, maybe not. When I installed, I let the end links hang from the top bolt hand tight not attached at all on the sway bar, then tightened them to the frame of the truck with the stock bolt pretty damn tight, I put a lot of a$$ into it because I knew there was potential play there. Should have taken a pic of that area, but with the elephant snot grease all over my hands, I opted not to get that on my phone.
TIP: The best way to get the elephant snot off your hands is to spray your hands with a penetrating lube, I use Aerokroil, but WD40 or whatever you have would work. After spraying, rub hands together to break that snot up, then wash with fast orange or dish soap.
Test drive home is about 6-7 miles, took the long way over a couple of tracks and some big curves, much improved over stock and I was thinking that with the Air Lift spring bags, this would be negligible, but they cannot compensate for what this sway bar does, a very nice addition to my modified truck, ride quality is better than it was when completely stock.
