Thanks for the response. can you hear the tick at low speed and low rpm, and at normal highway speed or just when getting on it? mine dose it all the time, is harder to hear when i get on it hard but never shuts up! dealers can say it normal thats buillshit. manufacture new models to be smoother, quieter and better insulated in the cabin and these trucks rattle like a 6.9l diesel. none of my previous steel body 6.2 sound like that at all, infact i have a higher milage 16 for a rental right now it dosnt tick at all!
