I've developed a noise in the right rear of my X that I can only ear starting from a stop. I don't know if that is because it stops at higher speed or I can't hear it at higher speed. It's kind of a ticking/clinking sound that is definitely associated with axle rotation.

I put it up on jack stands this weekend and put it in gear and listened at the rear axle, bearing, etc with the wheel off. It didn't make as much noise as when driving, but it was making a click/clinking noise as it rotated. Because I've hear "clicking" is associated with a bad CV I listened to everything in that area with a stethoscope.

The sound was definitely not coming from the CV it was where the bearing is located. So, I'm pretty sure it's the bearing, but from my research, they supposedly make a "wah wah" noise when being driven. I don't have that noise.

Anyone have any ideas? I went ahead and ordered a replacement, but I can return it if that isn't it. And I'd prefer to not go to all the trouble if it is likely something else.

Truck has 256,000 miles and is throwing no codes. (Since I changed the transfer case gear two weeks ago any way.)
