I do Land Rover diffs.. bearings rumble, gears whine.. in my experience whines are from wear not usually from bad install. Bad install will show up in the wear pattern. But most likely the sound is due to old gears mixed with new settling bearings hence it starts after 5k
Hopefully, you'll get more than 500,000 km from this one! Gee, new crown gears are a work of art. Looking forward to the next installment. Thanks Anthony!
Generally if you can change the diff noise using the accelerator pedal it's the crown wheel and pinion issue. If the whine is constant usually it's a bearing issue. Backlash between crown and pinion doesn't reduce clunky driving, 50 percent of the problem is internal diff gear setup. The other 50 is axle splines tail shaft slip joints and other areas.
See how easy it is to get it wrong Not easy to diagnose maybe easy to change Bearings but it’s not the Bearings The bearings were done by a different specialist, which has proved it’s not that easy because even the specialist got it wrong wait and see 🤔😮😀😉🙏✌️
To me Toyota has gone backwards. They don't keep parts in the country like they did. Try and get a new model engine. Even a diff you had to wait long time. Support is badly lacking.

Three months from Japan.!! Oh what a feeling 😂
It sounded like the front pinion bearing to me, it's an easy job to rerace these diffs.

What oil you using in that diff?
Did you have a locker on this vehicle ?
If it was only the pinion oil seal you could've replaced it without a rebuild.
