Had a disturbing problem today. Sometimes, when I turn, there is a loud semi-metallic rapping noise that comes from the transmission area. <img src="/forums/images/graemlins/scared.gif" alt="" /> <img src="/forums/images/graemlins/scared.gif" alt="" /> This only happens when turning at medium to high speed. It happens a lot on onramps. I've been able to reproduce it by doing tight, fairly fast circles in a parking lot. It's very unnerving, I don't know what could be causing it. I suspected a problem with the center differential, but I cycled from 2Hi to 4LoLC twice and still had the problem. That raised some questions too(long engage/disengage times) but I'll address those later.

Any ideas?
