That wear does look pretty nasty tho... probably a good thing you changed those out anyway.

May be bearings on the prop shaft.

Well guys,
I tried some tests today and recorded the video below. 1080p with high volume helps.

The first part of the video is the high pitched noise. I couldn't replicate this on the axle stands. At around the 10 sec mark you should hear the "SHEEEE" noise.

I could replicate the rumble noise on the axle stands. The rest of the video shoes this. Check out 1.49 sec mark.

At this stage i'm leaning towards the differential. I think maybe the low speed rumble and high speed "SHEEE" noise could be the same bearing(s), just at a different frequency.

Also, i've replaced the diff oil and repacked the cv's with grease.

Thanks, it seems to be where the propshaft joins to the diff. It sounds almost like the rumble is from the pinion/crown gear.

Any other ideas/anyone seen this before?

Did you ever resolve this, OP? I have a similar grinding/rattle below 2500rpm under load, but no whining noise after that. Car only has 4150 miles on it, so hopefully it's nothing major. Thanks for any info you have!
