Thanks everyone. I'll be crawling under it tonight to check it out. I had thought of the linkage as well, but since it's new to me, I hadn't had any opportunity to actually start digging into it and sniffing out the little quirks.

There isn't a T-case drop to the best of my knowledge. It's stock height so I wouldn't imagine the previous owner would have a need to install one.

I'll try the suggestions and report back when I get off work tonight.
