I was wheeling around in my 2006 jeep cherokee 4.7L and I disengaged the 4wd ready to drive off. And then I went to drive off taking a left and it gave me a wicked clunking sound. While I accelerate now it gives me a clicking sound. Then it stops and then while driving at regular speeds it sounds like a loud hissing or very fast clicking. It also pops and clicks while driving up steep hills. Any ideas?
