Pulley hub bearing
 

Done some searching but still a little unclear. The pulley that the fan clutch bolts to (yellow circle).....have folks removed the bracket assembly, that the pulley bearing is pressed into, and successfully had a machine shop press the old bearing out/press a new bearing in? Is the bearing assembly common? Bearing number maybe?

We get a momentary squeal (passenger side) on a cold morning start (suspect a bearing going dry). All but eliminated the compressor but that leaves the pulley bearing and alternator. 72K 4.0L. Thanks.
