Whistling while towing uphill
Hello, when towing my travel trailer uphill (weighs 4700lbs loaded) my 04 FX4 5.4 /3.73 make a loud whistling or screetching noise only when getting on the gas, if I keep it steady it won't do it, only while accelerating hard. The dealer has checked it and says he can't find anything. The only person with me when this happens is my wife and she's not good at finding noises while driving. Any ideas? Thanks
