I am having an issue on my 2015 Xterra Pro4x, it is Titan swapped on 35s.
Starting at about 65MPH I have a humming that comes with a slight vibration, continuing to about 80-90ish MPH you’ll hear the noise.
If I let off the gas it changes pitch and will make the noise until I go below 65mph. If I put it into neutral the noise goes away completely.
I have replaced all the bearings in the rear diff (timken carrier/pinion bearings) and the axle bearings have been replaced about 20-30k ago with oem timken bearings as well.
The rear diff also ran a good pattern when it was set and done.
I also know it’s not tire noise because I have had a separate set of tires since it started making the noise, went from 35” Ironman MTs to 35” BFG K02s
I hear the noise throughout the whole vehicle it seems. I’m really hoping it’s not a Transfer case or transmission issue. I plan on taking the Xterra across country in June and that’s a lot of highway driving at about 70-75 (when the noise is occurring)
Anyone have any clue or idea?
I hope yall can point me in the right direction
