Wow - what an old thread - and now I should update!!

The "final" solution to this problem was replacement of the steering knuckles with FACTORY NEW. I did one knuckle at a time, about 45,000 miles apart (about 9 months for me). When I inspected the first knuckle I changed after 45,000 miles it was still new in appearance with the factory machining. When I set the bearing preload I use the factory procedure...
