U-Joints will clunk when you change from R to D, and vica versa. When they do die, they make a hellacious grinding noise that's like rocks being crushed, and also a constant scraping/whiring/whining noise as you put a load on it (acceleration). Needless to say, scary noises!
If the clunks came after the lift, check all suspension bolts.
Manually shifting an auto does nothing to save your rear end. Every mile you put down damages it more and more. GM axles are dirt cheap, I picked up a 3.73 12 bolt (stronger than yours) for $300.

Well I only shift it when I am stopping, which is when it clanks as I slow down I know were the shift point is speed wise & rpm wise & I down shift through the gears until I am stopped. Which keeps there rear from clanking if I do that, if I don't do that then It clanks until I am stopped.
Also I am on the hunt right now for a 12 bolt rear end with 3:73 gears (Like the one I have now) & if I can get one with some disc brakes & maybe a posi on it that would be nice.
