"click click" in rear end upon moving

When I move from a stop in Drive or Reverse, there is a clicking noise coming from the rear end of the truck. Usually two clicks. Happens everytime I set off.
Have seen some posts about this but havent really seen a clear answer. Just recently purchased this truck used with 80k miles. New to owning a truck in general so im not familiar with servicing driveshafts or u joints...I did check fluid levels on both diffs already but i dont know where to start as of right now. Any help is appreciated!

Check out the universal joints on the drive shaft. They have been known to do that in all vehicles.

If it sounds like it is coming from the front you may want to check them up there too with that 4x4.
Mine did something similar. I have a Dodge brand of posi rear end and the unit went bad. It was able to be repaired, however the mechanic stated that it is a weak design and should be upgraded to a heavier duty unit. Most of the posi units require an additive to the fluid and if it is not put in, you will get a grinding noise. You might try that first to save some $$.
