I have been having a strange problem with wondering vage steering . I did all the normal stuff , all the linkage ends ,gear box adjustment front end alinment. then my daughter said "Dad how come it does not return to center" lol Turns out it was a gummed up ps pump control valve . I removed it and some how it had stuff pluging it up . After cleaning it up problem solved. I did have to readjust the steering box , it was way to tight, Just a F.Y.I.
