Need help identifying this squeak. Maybe bearing, maybe speedo?

I'm leaning towards speedo cable. I put the camera on all 4 corners and it's loudest over this wheel (driver rear), and second loudest over driver front. I can hear it well in the cab with the windows rolled up. Makes the sound in gear and out. With brakes and without.

Skip to 1:50 or so.

I would suggest you disconnect the speedo at the trans and go for a spin. If it is still there it sounds like a U-joint squeak to me.

Just pop the drive shafts out real quick and see if the caps that you can take off, look if they're rusty or dry

Connected to my trans is a stewart warner speedo reducer (because it's impossible to get the right drive and driven gears for my rear end), which I thought might be it. I disconnected the speedo wire from it and the sound went away. I picked up a new speedo wire yesterday and will install it.

I needed to take the cluster out anyway for some R&R. so I guess it all works out. :)
