I need to use a new crush sleeve if I use new bearing.

With the solid spacer you must adjust the length with thin
shims (washers) until when the nut is tight, the pre-load on
the bearings is correct. Not enough shims and the bearing
will lock up. Too many shims and the bearing will be loose.

With the crush tube you tighten to 108Nm and the tube will
compress. Alway check that the pinion is still free to move
while you are tightening the nut. Check the preload and if
the bearing is loose, tighten the nut little by little until the
preload is correct. Sometimes it is necessary to tighten the
nut more to get it to start to compress... up to 235Nm max.
If the crush tube does not compress, replace with another
new crush tube and start again.

If your crush tube is already compressed and not long enough,
you must get a new one. Too much preload will quickly destroy
the bearings. Not enough preload and the bearings cannot
work correctly. They will wear out sooner and allow the pinion
to move around, possibly causing noise from the pinion not
making a correct contact with the crown wheel.

As I can understand I have to use a new crush sleeve.
