Suspect rear wheel bearing broken

hey guys,
I have a Jimny 2002 and been hearing a humming/grinding noise for the past week. I finally got around at looking what is it really.
I thought at the begining that it could be the breaks but after oppening the drum it looks like the breaks aren't the problem.
I've attached a video of what I can hear when rotating ... it doesn't sound good. The only thing i can think of is the bearing.

What do you think ?

It could be a wheel bearing if it has collapsed, but I am not sure the sound is correct. Normally they rubble for a while then when they collapse the car is usually unable to be driven, at least that has been my experience.

I wonder if it is a drive shaft or the rear diff?

If you put the car in gear does it still turn easily or does it lock? If it still turns easily then it’s more likely to be the drive shaft or diff than a wheel bearing.

Someone else might know better than me on the Jimny.

Put the back of the car on jack stands, if you have someone to assist you, get on your back under the car so your head is between the diff pumpkin and the wheel and have your assistant turn the wheel, you should be able to tell which ear the sound is closer to. If you're by yourself, put the wheel back on so you can turn it from under the car.

First choice is a mechanics stethoscope or second best a long handled screwdriver. If first choice place rod next to bearing housing or if second choice use tip of driver at same place. Turn as in your video. Then try at diff.

that's a good idea. I'll do that in the weekend.

Quick update on this. I drove the car and there was a moment where it became unstable, i honestly thought i've blown a tire so i stopped. No tire, but it leaked oiled from the break drum. So i guess the oil seal hos gone now.

Planning to to pull out the shaft? out and see what's broken. I've ordered a seal and a bearing kit. I hope that's it and not the diff.

Unfortunately a collapsed bearing and a broken shaft would both potentially cause the oil seal to go.

You can easily check for a broken shaft, just jack the wheel, put the car in gear and with the hand brake off and see if the wheel turns. If it does, either the drive shaft has snapped or there is a fault with the diff.

If it is locked in place (by the engine and prop shaft then it won't turn.

You could also try in in neutral and turn the prop shaft by hand, the jacked wheel should rotate.

If the bearing fails the wheel and half shaft can fall out!

Change the wheelbearing and it should fix everything.

Don't turn the wheel round by hand when one is off the floor, or you will be absolutely convinced from the feel and noise that there are shattered teeth and broken bearings in the diff.

It is just a characteristic of the 4 pin suzuki diff!

If it suddenly breaks, go back to the last thing that you did before it broke and start looking there :)
