Toyota Tacoma Front and Rear Differential Drop Kits (Does it help with vibration after Lift kit)

Hey everyone, after installing the new front and rear suspension on the Taco I had vibration from the front driver side. I knew that this was possibly the needle bearing taking on some stress after the lift kit installation. I bought a front and back differential drop kits to possibly help with the issue. Does this help or am I going to have to pay money to swap out the needle bearing? You'll have to watch for the results.
