power steering pump seal blowing out....5 times now

Try one more time. Check the suface where the seal meets the housing. Remove any scars. A light coat of rtv on the bore surface wont hurt anything. Place a new seal over the shaft and against the bore. Sit one of your useds seals upside down over that one. Now drive on the old seal to install the new one. Drive it in just deep enough to install the cover washer ( if equiped ) and the snap ring.
