Conversation Between Racerguy and Lawdogiii

I'm brand-new to this forum and read all 13 pages of your posts about replacing upper/lower ball joints----Here is my problem----my son's truck 2002 Ford F-150 4X4 has a problem,,,the passenger side tire appears to lean in slightly at the top,,,,and the upper tierod end is slightly rubbing against the tire. The local dealer advised $750.00 & a new steering knuckle MIGHT fix it. What do you think?
