Kind of a funny story that made me feel like a complete retard. I bought a 2004 dodge ram 1500 SLT about 4 months ago. Well about a week ago I started hearing a sound like a actuator having a hard time doing its thing, it also sounded like it could have been a vac line. It would happen every now and again. So yesterday I checked every thing and all appeared good. So my buddy and I jump in his truck (a 2012 Dodge ram 2500 diesel) to grab beer, after a few minutes I hear his truck do it! I was like WTF? Buddy looks at me with a "wtf look" and smile and kinda chuckles as he hits rewind on stereo. Turns out it has been a sound in a song... FML! haha
Here is the song so ya'll can hear it... its at 30 seconds and kinda hard to hear on laptop, but its there and drove me nuts for the last week.
