herez why i asked, if the bearing was changed by only the removal of pully, then only seal that pump can suck air is the pully shaft seal under the bearing, and if housing is opened for any high pressure device such as car ac compressor or ps pump only torque wrench tightened bolts will ensure even seating of housing together or else it will make problem only on high temperature, perhaps thats why they always say to change the whole ps pump no matter what happen to that jack thing. anyways will be following thread and waiting for updates as i also need to have work done on my city 2k ps pump
Edit: xulfiqar commented above one as i was typing mine reply
