So I bought my truck with 42k miles, at 70k, I started hearing a humming sound from my rear-end when it is under load. I did a brake inspection and found a right rear axle leak. Replaced both axle seals and fluid with redline, plus the friction modifier. The rear-end was full of water when I pulled the cover... After that many miles full of milky fluid, what would cause the humming when the rear is under load? I'm thinking gears, or carrier bearings, but want to be sure. Anyone ever dealt with this before?
