Sorry guys, I got busy and distracted. Forgot to get back on here. I have since figured out my problem. All it was was a bad cable, I replaced it and the PTO will now disengage fully like it should. But to answer your questions, I drove it about 100 miles from where I bought it back to my place. No unusual noises. Obviously, it engages with a cable. Everything works fine, the box lifts flawlessly. The truck has other issues, but I suppose those problems are for another thread. Thanks for the responses.
