It probably is the uppers, but there are occasions where it isnt. Certainly in my case, I had the same problem, insanely annoying, so loud it turns peoples heads...
I replaced my uppers, and the creak is still there.
I disconnected the ARB and went for a drive and noise gone.
Its worth replacing the uppers anyway as in most cases they are the cause of the creak, but also you'll notice a huge improvement in handling assuming they havent been done for a while.
