Thanks to this site I successfully completed my front brake and spindle R&R. The details and advice saved me time and money. I am now doing the rears and looking for some torque specs. I need the following or a site that could give me the info please:
Axil bearing nut
Hub to rotor bolts
Caliper bracket bolts
Caliper slide pin bolts
Differencal cover bolts
99 F-350,(6-99)7.3, dually
Once again, thanks in advance.

"Axil" bearing nut = I don't see one. If you mean the pinion bearing nut, that puppy is 470 lb/ft. And that's not a typo; almost 500 lb/ft. If you mean the 8 bolts that hold the axle into the housing, they are 98 lb/ft each.
"Differencal" cover bolts = 35 lb/ft
My Sierra Blanca in the sig pic was a great pickup for 11.5 years. I sold it a coupla years ago. I drove a hand-me-down 2003 F-150 SuperCrew 4.6L 2V for a while, but it was unacceptable for towing more than a rowboat. Replacement is a 2012 F-150 EcoBoost SuperCrew Lariat that tows my 5,000-pound TT like a dream.
Thanks for the info. Just what I needed to finish the job. The bearing nut I was refering to was the large nut that holds the entire hub assembly to the housing and preloads the bearings. (Using the four prong wrench). My bad on the explanation. Still need that spec or procedure please.

4. Slide the rear hub and brake disc assembly over the axle housing spindle.
- Remove the electrician's tape.
5. Install the outer rear wheel bearing.
6. Start the hub nut making sure that the tab aligns correctly in the keyway prior to thread engagement.
7. NOTE: The following hub nut tightening sequence will prevent side-to-side end play of the hub and brake disc assembly.
NOTE: Apply inward pressure to the socket to separate the ratcheting components of the hub nut.
To adjust the bearings, tighten the nut.
Tighten to 95 Nm (70 lb-ft).
8. Back off the nut 90 degrees.
9. Tighten the nut.
Tighten to 24 Nm (18 lb-ft).
To verify that there is no side-to-side end play, attach a magnetically mounted dial indicator to the spindle end and place the dial indicator tip on the outboard surface of the hub. Check for side-to-side end play.
Final bearing adjustment has zero end play. The maximum torque to rotate the hub is 2.3 Nm (20 lb-in) when end play is zero.
10. Install the axle shaft. For additional information, refer to Axle Shaft in this section.
11. Install the anchor plate. For additional information, refer to Section 206-04 .
12. Install the tire and wheel assembly. For additional information, refer to Section 204-04 . </div></div>
SmokeyWren, thanks for the reply. That is the nut I am talking about. Your information is greatly appreciated. Just wondering what the electricans tape was used for in step 3 (can't see in your posting). Thanks again for taking the time to foward the information.
Gee, just when I thought I new it all, the more I read the more I learn. I was just going to soak the bearings in rear end oil so they would not run dry for the early run in. Lightly pack in grease? Do you recommend a certain grease? And lightly pack? If they run in oil why would you grease them?
