I felt a little vibration in my truck after I did my lift, wheels and tires and thought it was just the BFG's. But after about 1000 miles the vibration has gotten worse. I put on my stock wheels and tires and the sounds and vibration got worse. And I just put in my stock leaf springs last weekend thinking maybe something was wrong with my deavers, and that did not help at all either. Tomorrow I am putting it all back to stock and if I still have the vibration, its going into the dealership, ugh...
