I jacked both front tires but removed and installed one sway bar at a time. Then I jacked one at a time for the rear. I noticed some members said to do both at the same time (Front or Rear) but I found it to be the same whether I had both jacked or only one tire.
Remove the top nut first on the stock sway links as mentioned by other members, it can be difficult to get off, spray with WD40 or Kroll Oil first to help you in getting the stock nuts off. If you have an impact gun, break the top nut loose then remove with wrenches. Then do the bottom nut in the same manner.
Grease the Bwoody links and stick the washer to them for easier installation in the rear where it is tighter.
Go buy more MODs with the 300+ you saved in installing them yourself.. hehe
Vast improvement in body roll. I immediately noticed a difference when only the front was done and I was turning the Jeep around to do the rear. Would do the change again, took about 3-4 hours for all four.
