:angry:here goes, run car hot while back replaced the heads. in process when i got evrything back together, with new water pump, new idler and tensioner pulleys,new drive belt. noticed power steering whine after reassembling lines. typical air in steering! decided everything new replace power steering pump too. oh yeah 3.0 OHV. after assembling everything still cant burp the air. thought i might be pulling air in at the typical tie-rod end boot on passenger side. removed boot no power steering fluid in boot just grease on joints inside boot, actually looked rather new. so i've followed the purging air steps by jacking vehicle up, attaching vacuum, pulling -25" to turning steering side to side, still foaming up and puking. dont have a single leak nowhere except when it spews out steering reservoir. whats next to get whine out of steering pump?
