The truck drives fine. It accelerates fine and everything, except there has been a humming noise coming from the rear when I accelerate recently. It gets louder the faster I go. The dealer seemed to not know what it was a first and gave me different possible issues. Now they’re telling me I need a rear differential replacement. I do have larger wheels and tires (35s) on a 6 in lift. Have any of you experienced something similar?
Truck drives fine but obviously it isn’t good. Haven’t noticed any oil puddles on the floor or any big leaking. What you guys think it can be? Here’s a pic.
