Have a question for you guys out there. I was testing out my 4x4 for the first time a bit ago. She engages ok and the 4wd light comes on. She drives down the road fine. When I stopped to pull her out of 4wd to 2wd it took a bit of strength to pull the lever down and then I heard a big clunk. It almost had a tight wound up feel in the rear end if that makes sense. Any ideas? Is this normal?
