About a week ago a noise that sounds real squeaky/grindy is happening on my 93 Cherokee. While just idle no noise but until about 30-35mph that noise just winds up. I shift into gears fine too. It almost sounds like it's coming from below me which makes me think something along the lines of the driveshaft. Anyone have this problem or have any ideas?

 

old suspension components? faulty exhaust hanger? U-joints? Transfer Case? Fluids levels?

 

Like said you have a lot of stuff right there that could make the sound your hearing.
