I had 5100's installed all four corners in July. No TSB or anything in the rear, and set the fronts at 1.75. Driving away from the shop I could feel that the ride was SIGNIFICANTLY IMPROVED. I no longer felt every bump in the road. However, I do feel a slight vibration, starting around 30mph and fading out around 65mph. It's not a terrible vibration, but noticeable in the floor, pedals and steering wheel. From what I've read in many threads here, it is a strong possibility that lifting the truck has uncovered (or aggravated) an existing problem with the front differential bearing. Apparently, (fingers and toes crossed) this is an issue more because it's irritating, and NOT so much because it is unsafe or could cause a catastrophic failure. Sometime next week, I think I may drop the front to .85 and see if that alleviates any of the problem, or at least lessens the vibes. Other than that, no real issues after the level. Hope this helped.
