Do you actually need the axle thrust washers?

When replacing the rear wheel bearings do you need the rear thrust washers?

I had a broken thrust washer on my rear axle and the cars tail end would go side to side during hard acceleration and sometimes I would even have to let off throttle because of that. After they were replaced the car is solid with no wag.

I've replaced the hubs w/o them before, and I haven't died yet.

I'd prefer to use them, and the last one I replaced I did use one, but the first time my mechanic and I couldn't figure out what it was. It came out pretty mangled. The new ones are a bit thicker.

How does a broken washer cause that?

No idea, but they replaced the thrust washers and axles under warranty and the issue was gone. The other symptom was a noise from the rear axle every time when going from drive to reverse. I didnt think the clunk and the rear end sway were related at all but when they did this both the problems were fixed. I Had been having the rear end sway for quite a while and I just thought my whipple was overpowering the rear suspension causing the sway so I was planning on going coilovers, but then this solved the sway, but I still got coilovers after this anyway.

Is there a trick to separate the axle and hub.

I had a drivers side washer fail so pathetically about 30k miles ago that I declined to replace it. Car still works as intended.
