Bad Rear Wheel Bearing?

[Wang.S]

It sounds dicked up bad, but I have nothing to compare it to, as I have never done that on mine.

from an investigative maintenance standpoint, is the other wheel on the ground or in the air?
I would try and isolate one side from the other and compare. As well, disconnect the driveshaft to isolate just the rear end from the rest of the drivetrain.

Sounds like normal differential spider gear sounds.

Man, not good! Is there even oil in the diff?

I second the thought is there any fluid in the rear end or not enough. Pulling the fill plug and having a look will put that though to rest or give you something to take to the dealer to record the problem and then do a pumpkin cover pull and inspection and a new fluid fill.

Ooof... she's pooched boys.

I agree its time for new tires. I did verify the wheels are on the hub flush and verified the lugs are torqued to spec. Here's a video spinning the rear wheel. Is this normal?

What has been the conclusion to both noise? Is it the axle bearing? I have the same noise from both of your videos. I am trying to find out if it’s normal or not. I have 39K miles on my Tremor.

Probably caught on fire by now.

Check your diffs! Looked at my lube level last year at 30k just as maintenance, 8 ozs low! No leaks, just never topped off.

I had the exact same noise when spinning the tire on a 2021 Tremor at 70k kms (44k miles). I changed the rear diff fluid and the noise went away after 4-5days of driving (apx 150kms/100miles. I don’t think the fluid was low, but I didn’t measure it to confirm. Maybe it was just too dirty to properly lubricate the wheel bearings.
