When my water pump went, i also had a "grumbling" noise under the hood. With no belt, when you try to turn the pulley, you should feel a sort of "gritty" feeling.....just not nice and smooth. that is if it is the bearing/bushing thats bad.

My 97 ZJ had that grumbling sound. I took the belt off and I could move the fan blade sideways about 1/2"! It still wasn't leaking or overheating, if you can imagine that. It's a 4.0 after all.

The impeller blades on some/all chain store water pumps for the WJ 4.0L are plastic, and can become loose on the shaft or even break off, causing noises and overheating issues. >http://www.jeepforum.com/forum/f310/...eller-1442660/

I bought mine at NAPA as heavy duty lifetime warrenty, I made sure it was metal. What causes them to shatter is the bearings wear enough to allow the impeller to strike the cylinder barrel. It only takes about 1/16" movement to do that. Mine was worn enough to leave a deep scratch on the cylinder barrel.
