Pull and push them too, loose bearings are generally noticeable. You will need to loosen the belt to feel the play - ask if you need instructions on doing that. As Fred mentioned, there is the upper idler on the tensioner (which they may have replaced) and I think the '99 still uses the center idler pulley. Those usually last a long time. Note that it is not unusual for the alternator bearing to have wear. Water pumps go too but you can usually feel the bearings. I'm a little concerned about your PS pump if it was close to dry. It could be damaged and making noise. Another trick is to use a mechanic's stethoscope, which you can buy for short money at an auto parts store (usually under $20). Please be exceedingly careful if you use it near a running engine - one wrong move near the spinning belt and it becomes a flying weapon instead of a useful tool.
