I’m hear a sound from the rear at 50+ mph, esp on flat but not newly asphalted roads.
I’m trying to decide whether it’s the rear wheel bearing or the CV
Any tips on how to pinpoint the problem ?
Can the source be I pointed by running the car on a lift ?

I've never heard wheel bearings squeal. They make a lower droning/growling sound. A parking lot may not be fast enough to detect. On the highway at 30+ mph gently use the steering wheel to rock the car left and right to load each side of the car. If it growls when you steer left its the right side and vice versa. Could also be your gearbox.

Shift into neutral when you hear the noise. If it disappears it's your transmission. I bet it's the wheel bearing though. If it disappears when you turn one way or another, then it's very likely the bearing. And yes, you can change them without removing the trailing arm. I made a tool using an allthreaded rod and a bunch of big washers/bolts to press out the bearing. I replaced both bearings for continuity sake. Removing the first one was a huge PITA, but after figuring it out, the second one was easy.
