John:
I had the same problem. Mounting a Thule #555 fairing on the front of the front roof rack took me from a howl to no noise at all. I had to use 3 Yakima Mighty Mount Wing horizontal clamps part # 3601 and some longer bolts to do the job. I found them at Mountain Gear, but understand that Isuzu bought most up and raised the price from $6 to $28. It took some creative bending of the Thule bars that came with the fairing. I bent them with my hands to a very low angle.

So on and on I go, the seconds tick the time out
There's so much left to know, and I'm on the road to find out.
