Hi mate, I don't know what the answer to your problem is, but putting soap on a belt to "lubricate" it is an old truck drivers trick to find which belt is squealing, (back in the days before single serpentine belts). It is not a fix but just for locating the noise. Yes it is possible the soap masked the squeal until it wore off as it does not last long and is not a fix.

Do you still have the old belt to put back on ? Also is it a genuine Mr Nissan belt.
Bit of movement in that pulley I'll go and check mine.
Edit:::: Just checked my pulley and I couldnt get it to move no matter what I did

Just watched the vid and I don't think the end play in the alternator pulley/clutch is correct. Do you know if the pulley get hot when running. That would indicate mis alignment. Alos is there any sign of wear on the edges of the belt. Can you remove the belt or alternator and feel for end play in the alternator shaft?

I just added a better slowmo to youtube https://www.youtube.com/watch?v=cuc3fAVxxX8
Seems quite a bit of movement on it.

As I said earlier mine has no play at all and its a reasonably new alternator 40K old.

Just tried to move the pulley by putting a screwdriver between the pulley and the alternator and get no movement at all.
It's not until the internals of the alternator stop turning that the pulley stops pulsating.
Threedogs: I still have the old belt but that was making more noise than the new one.
Perhaps the sides of the old belt has worn a little and may be moving more.

A few people have reported that the only fix to their belt squeal, after trying several, was a genuine belt... but that means it has to be the belt and not a drive pulley or ancillary bearing (Alt, A/C, Tensioner etc) squealing (obviously).
The Alternator has a Sprag Clutch in the pulley assy.
The reason for the sprag is that Mr Nissan is trying to damp out belt whip when the engine stops
If the sprag is faulty it will squeal louder than a Forum Veteran when a Newb posts 25 loads of shit to get a manual.
Then there are two choices...
A) replace with factory sprag clutch
B) replace the Sprag or 'Overrun' Pulley assy with solid drive pulley
Not sayin it is the sprag but don't rule it out
