the pic is of a typical MQ front diff pinion shaft.
The "crush" tube is a spacer that is there primarily as a spacer but is also utilised as a shim, When they are installed at the factory the spacer is crushed down to the correct clearence for the bearing.
To remove the pinion one must "count" the number of turns the nut is undone and do it back up the same number of turns to ensure the clearence is maintained.
I have seen pinions that have been done by rank amatures and the pinion bearing has never been seated correctly, this results in either a sloppy fit or an overtight fit..... either of these will result in the bearing failing.

the GQ front is high pinion though, and I _think_ leaves japan with a solid spacer. while the rear has a collapsibel spacer, or it might be the other way round, I can't remember....

Don't know much about Nissans. DON'T use crush tube with high pinion - thrust on pinion is wrong way.
