It's a pity you didn't measure the worn spacers.
The 360 ft lbs of torque is not bearing against the circlip. You could assemble the stub axle, hub, and bearings outside the bearing housing. The big nut presses the hub against the inner race of the outer bearing, which presses against the spacer, which presses against the inner race of the inner bearing.
In other words, the stub axle is like a big bolt, with the nut on the end pressing what ever is between the nut and the head of the bolt.
The outer bearing has some play in it even when new. I just checked a brand new one and I can make the inner race rock slightly.

I “consider” over 1/4” rock excessive and therefore recommend replacing the bearings and spacer. HOWEVER, “sometimes” if the wear has been excessive for a long time the hub end will have worn and it too will need to be replaced to make up the correct length. NONE of this is indicated in the Bentley, it is from my own observations. AND to add more to the confusion, I have NEVER been able to understand why the 360 ft. lbs. of torques is needed on that axle nut. It’s just compressing the hub, bearing inner races and spacer up against the circlip on the axle.
