can someone please tell me the signs of a sick power steering pump and also the sighns of a sick idler pulley?

a sck pump would consist of extra turning efford eg: you have to work harder to turn the wheel, allways sqeeling or makeing a grindling, ruble, humming noise, severe leakage, that just names a few, as for idler pulley squeeling, rattle, rumble, useually if you can hear the bearing it's buggered best way is to pull the idler off turn it in your hand if it feels lose or you can feel it gets hard to turn it's buggered.
