1ns you definitely eliminate brake, you got no other option, if the noise it that bad. Still hard to believe they are needed with that little play.
My best to you.
You got everything out of the car b4 making that video right?
Hard to make a decision based on no hands on, specially when you can't hear it when manually spinning wheels.
Based on that I would suspect the wheel bearings rather than carrier bearings. However, depending how bad the axle bearings look, it may be wise to change the carrier bearings if the diff oil has a lot of metal particles in it.
I'm assuming that since the noise is so soft and I didn't have any noticeable play when I tested them, that they are probably in the beginning stages of going bad?
You r probly right being in the beginning of going bad, since i have done 4 wheel bearings in the last couple months, and I had no prob pinning it down.
Regardless, since you r going to be taking the rear apart I do everything. If you do the wheel bearings first, check them well see if they are the issue, that way it would minimize work. However, have everything on hand before you put the car on the lift. if I had to roll the dice, I would say left wheel bearing.
