Ques: Why do some billet grills hum?
Ans: 'Cause they don't know the words?? <G>
Seriously, there have been some complaints about humming billet grills. Mine does it. You've gotta be going more than 75 MPH, but you can hear it. It doesn't bother me very much, what the CD's pumpin' out Garth Brooks and and the Flowmaster duals rumblin' away. On the other hand, I promised to work on it, and I am.
Now, my particular grill is from Stull Industries. So far, they've been most co-operative. The lack of timely progress has been my fault. I know I promised an update in "a few days" some time ago, and haven't posted anything, but I offer a few excuses:
1. A business trip to San Antonio stretched into an entire week.
2. On the spur of the moment, we got the chance to spend eight golden days with two delightful grandchildren in Maine.
3. Of course, everything really stacked up while we were gone. I'm almost caught up at the office, have the yard almost under control, and contacted Stull Industries this week.
Stull thinks it could be a problem with more than one Tundra grill. They've had humming problems in the past, but mostly with motor homes, where the individual billets are LONG. For those motor home grilles, they developed some sound deadning inserts that go behind the grille. Just narrow strips of notched rubber, but Stull says they did the trick on the motorhome grills.
As soon as I get these little rubber pieces, I'll try them out and report.
From e-mails I've gotten, I know some of you have been holdin' off on grille purchases while my Tundra serves as a test bed. In the next month or so, I've gotta be in Salt Lake and Houston, but I'll try to move this along.
