2005 Denali loud noise only when wet

[ljo]

My 2005 Denali has developed the most obscure noise I've ever heard, only when it's cool and damp, or wet out. It sounds like its coming right out of the LF wheel and has the sound of a seizing bearing or an electric motor going bad. It is very loud, not constant, and goes completely away in approx 3 minutes. It just hits for a few seconds, returns to normal and will hit again, then finally go away. It never makes this noise when its warm and dry out. I have inspected the wheel bearings, to find no play, and no typical wheel bearing noise. I have no trouble codes.
I'm stumped, anyone have any similar problems?

This is very frustrating ... if your truck was a Tahoe you would have had the best thread title EVER: "My hoe is loud when wet"

But no, you had to buy a Yukon.

On topic ... could you perhaps record the issue?
It might help folks identify it.

Well I was wrong in saying the noise was coming from the left front. It was actuallly coming from the left rear. It was the stupid parking brake shoes. No lining on either side. Problem found and problem solved. Thanks.
