I get a crackling/popping sound from the rear of the truck when I take off. Doesn't matter if I'm going straight or turning. But only does it at take off. The harder I accelerate the louder the noise is. Then it just goes away.. At 1st it would only do it when I was pulling a trailer, (thought it was my trailer making the noise) Been doing it for a couple weeks now.. I put a 3" lift on the truck 2 days ago and now it's doing it all the time.. Exact same noise I had when pulling trailer.. Any help would be greatly appreciated.
