Talking Loud roar from rear-end when over 30-40 MPH and on the throttle.

My 4Runner has a loud roar from the rear-end when I’m on the throttle and over 30-40 MPH. I’ve drained the oil in the rear-end and didn’t find anything out of the ordinary in the drained oil. I’ve replaced the axle bearings with no luck.

I’ve put 3000+ miles on the rig sense I’ve owned it and the noise doesn’t get any louder or quieter.

What do you guys think it could be?

I'd be willing to bet that it is the pinion bearing - they make an awful noise.
That is the bearing closest to the driveshaft in the third member.

PM - ZUK he may be able to help.
