Ok, Im going to knock out two questions in one post...hope that is ok. First question is: I have a 2005 4x4 4.0L Automatic. When the truck is in cruise control and at a steady speed there is a strange noise. It sounds almost like crackling or russeling paper coming from the engine bay. The truck drives fine and I have never had a problem (other then the one that will be covered in the next question). Now the mystery comes into play... My dad has a 2005 4x2 5-speed 3.0L that makes the same noise...I also had a 2002 4x4 5-speed 3.0L that made the same noise.Im thinking it is normal..but Im curious about what causes it... second question... My Inertia switch went out on me which is a common problem i have heard. But what is the best fix for it. I dont want to buy the harness and solder it in and stick the kill switch back on if it is just going to happen again. can I just connect the two wires together to get rid of the kill switch? or do I have to put the thing back in? Has anyone else fixed this probelm? is there a recall? Thank you for the help Ziggy
