driveshaft ? static drop w/ leafs

I just lowered my 1991 b2600 with belltech drop leafs in the back has anyone had driveshaft problems? I installed them and now I hear a loud clicking noise when driving, I wanted to know if I need to put shims in the rear for the pinion angle or not

is it a 2 piece shaft? and how may inch drop leafs?

yes 2 piece driveshaft maybe 3 or 4 inches

check your carrier bearing, it may have went buh bye

I just replaced the Ujoint and the noise went away but now I have a vibration that feels like an out of balance tire at about 50-65 mph but goes away at 70 mph. I had all my tires balanced and it still does it. Do you think I need a shim in the back and if so how many degrees??
