i have just replaced timing chain sprockets and belts etc.and when i got everything together i noticed an intermittent rattle from the power steering pump area.The idle pulley rotates with ease, took everything off and thought a little packing would do the trick but no avail. now its getting worse.Is there bearings inside the psp pump or pulley itself that would make the rattle noise.'86 2wd 22r ext cab with a long bed 164k. thanx for any help given <img src="/forums/images/graemlins/confused.gif" alt="" />
