There wasn’t whining, I did notice “slightly worn wheel bearing” sound coming from the front when we bought the car, I was waiting for summer to replace the wheel bearings, I guess it wasn’t the wheel bearings.
I’m assuming it’s been a cascade of issues, the flange bearing vibrating popped the axle out, which introduced the diff being drained of all fluid which made the flange bearing shatter due to overheating, and now I need a new diff. That’s what I assume happened.
We bought the x5 with the wheel bearing issue which turned out to be the diff, it wasn’t that bad sounding, it was noticeable but not imminent failure bad. So I figured that job could wait until I did everything around the engine was done. That’s before knowing it was the diff and not the wheel bearings.
