RE: H3 with a small growling noise at 1800 rpm
OK! I think I found the problem. Today I noticed a stud coming through the exhaust heat shield without the nut and washer, it looks like it fell off. There are two other studs with nuts and washers. I called Hummer and they say it in stock for .53 cents. I will go to the hardware store on the way home as the Hummer dealer is a long ways in the opposite direction.
Ill post later if this worked. Thanks All for your assistance!

SUCCESS!!!!!! Replaced the missing 6mm nut and washer noise went away. Also tightened the two other nuts that were still there and they were finger tight.
Noise GONE!
Thanks All!
One other thing, while under the H3 I noticed that the 1/2 inch bolts to the tranny pan were loose ( finger tight) and there was fluid weepage. Tightened them slightly,uniformly as the loose bolts are something reminiscent of my Harleys. Readers, might want to check these as they might be loose on your H3 too
