91102-PL3-B04 Is the bearing I'm specifically asking about.. Is it normal for this 2 piece bearing to make noise when new? Im building an s40 for someone since my first s20 build came out flawless. The NEW bearing even with lots of oil added in it makes a SLIGHT crunchy type sound? without much oil you get the "scha" sound when spinning it on the shaft (normal) but with a lot of oil added the noise is almost slightly crunchy sounding when spinning it slow (kee kee) and lessened to near zilch when spinning it fast. I do NOT want to have this all together for him and this bearing be defective ... Is this normal?

Does this bearing spin or just help side to side movement?? I don't remember when i built my s20.. 3 months ago hearing this but i wasnt as paranoid.
I've done some deep research into this and it says for roller bearings they do make noise.

Trans is back together and shifts fine into every gear but theres no way to tell what this bearing does noise wise without the shafts spinning in the car. (im not even sure what the bearing does as there's 2 stacked)

Aqua? Anyone know? (bearing is an ntn) Educate me please- Very interested.

Ok today i put an impact on the output shaft and spun full speed and everything sounds dead silent. Is this sufficient?

See attached video- please help- not pulling trans back out of car to change ONE potentially fault bearing. In this video here the bearing was not lubricated but even when it was majorly the sound is a little crunchy sounding still. AQUA, please answer.
