I would call back and see if I get someone else. When I contacted them they immediately knew and said they would send the grill out. That associate may not know but the company does.
In addition to changing the grill, which is simply a wire mesh screen they provided, I still had noise. I went around and caulked the side windows in the cab. All of them. Huge difference and much quieter. I also put down sound dampening material in the front cab floor. This also made a big difference. Before these changes we made a 12 hour trip each way and my ears were ringing for over a week. Lesson learned for me, test drive everything
