And right there you see why I do not use aftermarket manuals. There are mistakes in the Ford manuals, but they are few and far between. However, there are many mistakes in the aftermarket manuals, and they can cause costly problems.
Whelp! (And I don't mean puppies.) I had the Haynes in my hand so it was convenient and, I've found mistakes in the factory manual to my Mark III, my Saabs, and right here online in the manual to my truck, so I'm not convinced there are more mistakes in the aftermarket manuals.
More interesting is that I found a raging firestorm of a thread on a Ford Truck forum about the torque value on the locknut. There's filthy language and bomb-throwing -- it's a lotta fun. The suggestions range from 80 to 220 ft. lbs. Factory says 50, Haynes says 150. Now I have no clue what's right.
I put those bearings in the truck about 15 years ago when I rebuilt the front driveline and suspension and here weren't many miles on them so they shouldn't have gone bad. I can see that the races have run hot and the grease on the inside bearing was pitch black, though it was the outer that failed. It was really hard to break the locknut loose because, well, I used the Haynes when I did the job the first time.
