Remove the Hub and see if the gears that mesh together when you lock the hubs are not slipping. This was the issue with the Chinee hubs I had. I could clearly see the wear marks from the teeth jumping.

So I tested it out and it only does it when both hubs are locked in, had the hubs off the other day couldn’t see anything to wrong with them, they hard a fair bit of play but I assumed that was normal but could be wrong
And if I’m accelerating hardish if I’m just cruising it’s fine
And they are marked AVM made in Brazil so assume they are legit
Have you got any other hubs you can access to swap over to try. Just thinking unless you have a front locker one hub open wont work as a test.
Nah mate might just bite the bullet and buy some new ones, sick of the stupid torx heads on the AVM ones anyway haha and if that doesn’t fix it I’ll pull the diff out
I guess if you know there is no egg ring you've had the hubs apart ...... so did the clunking start before or after you had them apart. My car had no egg rings in it when I got it (standard manual hubs) & I was strongly advised to put them in, which I did. Without them there is room for movement, which may or may not be causing your clunk. It didn't in mine, biut I think I was just lucky & that it was only a matter of time before a problem arose. If I were you I'd buy some & fit them. Won't be a huge expense & it may fix your problem. Even if it doesn't you'll have had a good look at your hubs & know they are not a problem waiting to happen.
Ah just read you've had them apart & have some play in them .... it's possible the egg rings will take up the play.
