I recently completed a 14 hr round trip drive from PA to NC while towing a 7x12 enclosed trailer loaded with motorcycles and racing gear.
Upon returning, I can hear a metallic whine noise coming from the rear. I jacked up the rear on jack stands and let the truck idle in gear. I could not hear any noise coming from the driver's side wheel. A little bit of noise coming from the passenger's side wheel. The noise is loudest from the differential cover.
I had changed the fluid about 20k miles ago using valvoline synthetic 75w-140.
I changed the fluid again and it looked new. That made no difference in the noise level.
I was hoping that it was an axle bearing. I replaced both bearings. The passenger's side rattled around a bit more than the other side and I found metal shavings inside the outer tube. The diff cover was clean. I did not see any evidence of wear inside the difference.
The noise remains during my test drive. What else could the noise be? I'm thinking pinion bearing could be an option.
