Bad Rear End Bearing?

[KINGSUN_33]

Hey eveyone looking for some opinions on a new sound I've developed.

Coming home from a track day I started hearing a failing wheel bearing kindve sound or so I thought. Okay no big deal, jack up car and do my checks. Fronts, no play and tight, rears slight play (up and down) wasnt enough to see but I could feel it.

Check my rear end oil and it was at level and still in good shape (30k km) on the oil. Checked the brakes and nothing was off, same with u joints. (1 peice DS)

I did run the car on jack stands up to highway speed but Icouldnt hear anything close to what I heard driving so probably no load.

The sound is tough to explain, I know bad wheel bearings, rear end bearing sounds but the sound I'm getting is metallic if I had to describe. Not a chirp, rumble or growl. Won’t make any noticeable sound below 70kmh, around 80-120 is when It starts happening. Odd

I did try multiple different gears and sound continued either way, clutch in or out or coasting in neutral.

At this time I think it could still be the rear wheel bearings, no leaks either btw

Thanks,

I had the driveshaft noise around 100 kmh and it was just speed related and load independent. Bad CV/U-joint?
Wheel bearing noise should change in corners.

Has your rear pads got any beef left on them after track day?
