Interesting, I'll have to investigate that when we aren't getting snow dumped on us. Regardless I think I at least got my top nut tight enough, checked it frequently over the weekend on the camping trip and the washboards didn't make them budge. Now that the springs are settling though I'm absolutely LOVING the refreshed back end. Loaded up for the camping trip it was butter smooth, granted anything feels better than clapped out shocks and spacers though. Regardless the back felt great on washboards and the light flexing I got to do. Only problem is it's making me realize I will have to refresh the front end sooner or later >< BTW any tips on bending the rear brake braket to get a little more wiggle room there? I think I'm fine on it since I'm not deleting my sway bar but I tried to bend it and it was a bear, think I only managed 10 degrees or so.
