			First, take off the accessory belt and see if the noise goes away.  If it does, it's not the IMSB.  If not, the IMSB is in play.
 I don't see the Pelican as a complete upgrade.  The bolt is clearly better as the stock bolt necks down in what, in an ivory tower analysis, would be a great stress reduction cross section, but what in the real world equates to begging for a stress failure.  The Pelican bolt is far superior, so much so, I bought the kit just for the bolt.  I was not impressed with the NSK bearing itself as it was not a sealed bearing and was steel.  I replaced it with a sealed steel high temp Nachi 6204.
 
 You also did not state if you replaced a double row with a single row, which the Pelican kit does.  I would not make that move.  In any event the bearing is equivalent to a timing belt and needs to be replaced on a regular basis.  If yours is making noise, don't play around with it, replace it.
