I had the vibe immediately after getting the springs done, but as I drive it I can hear/feel various different things going on at different speeds, and all of them showed up after doing the springs and raising the truck a nice 3". Seems to me that much lift would affect many things some what, some more than others. Sometimes I feel it in the bones of the truck at around 55-60, sometimes feel it in the wheel, sometimes rolling to a stop, sometimes hear it with the window down rolling slowly next to a wall. All of them go faster or slower as the running gear does.
I think the way to go is to replace the u-joints first, then check the drive angle and see what's what after that.
Meanwhile, the old main spring is enjoying the ride!
...kinda wish I'd gone for one more leaf....
