Some of you know I just replaced my t-case. somehow my old one ran out of fluid. How that happened i have no idea. It turns out the only thing we can find wrong is that my exhaust is rubbing on my t-case. Its producing a squeak that sounds like my u-joint is going out. My question is can the heat from the exhaust burn off the fluid in my t-case? I'm starting to get a clunk on deceleration and I'm worried that I'm gonna blow another 'case tomorrow on my way to work.
