torque specs
 
Looking for two different torque specs for my 04 F-250...

lugnuts - 14x1.5 conical seat (if it matters). I searched and found 160 ft/lbs but no one that posted it seemed positive.

the new aluminum rear diff cover - I searched and found two specs. One was like 45 ft/lbs and the other was only like 25 or 26 ft/lbs. Again, this is for the new cover, not the stamped steel one.

I'd just like to know for sure what they are.

Thanks.

Tourque for lugs are 155 f/lbs(haynes).I would like to hear what the diff specs are.I have the new cover waiting to go on too.

If you are going to worry about the proper torque for your diff cover you have too much time on your hands. Just put a bead of sealer around it and tighten the thing down and you will be 'Good to Go'!! This isn't a highly stressed part, it just holds in your gear dope.

This is from an older post I hope this helps clear up the confusion. Also don't forget aluminum cover needs longer bolts. If I remember right they are 1 and 1/4" long 5/16" course thread.
