I'm getting ready to rip into the brake drums on my Dana 70 in my F250 to check the brakes and replace the ebrake cables.

question is-

What kind of / size of hub socket is it? My F250 is 45minutes away, so I can't really just pop in and look. The guy at napa tried to sell me one for a racheting lock nut (the newer sterlings) but I know Danas have a hex nut. I got a 2-9/16" one, which happened to fit the axle locknut for a 90s E350 (I think they used Dana 60s and 70s until recently?)..

hopefully, I got the right one (of course, it is a 3/4" drive )..

btw, what is the torqueing procedure for they, anyways?

 

Thats the right one; 2-9/16 hex.

Torque procedure is "damn tight" then back off a 1/4 turn. I'll see what the exact spec is when I get out to the garage and pull a manual.

 

cool, I'm glad I got the right socket.. btw, is your socket a 3/4" drive or 1/2"? Damn tight with a 3/4" ratchet must be @$%%ing tight..

 

Its a 3/4. Maybe I should say "damn snug". I've got a 3/4 breaker bar and I'm sure if I leaned on it hard enough I could fubar the bearing or race. Just lean on it a little untill it gives you some resistance then back it off a skosh. Oh yea...I need to go look up the actual specs. Back with an edit in a sec...

edit: okay, snug the bearing nut down to 50 ft. lbs to seat the bearing, then back it off 1/4 turn. Outer locknut to be torqued to 80-100 ft. lbs.

You've got a 3/4 drive torque wrench don't you

 

Nope, no 3/4" torque wrench.. I have a extra long 1/2" breaker bar that is longer than a 3/4" bar.. that will probably do

I'll have to stack a 3/4" to 1/2" adapter with my 1/2" to 3/8" to use my 3/8" torque wrench

hmm. I think my dad has a 1/2" torque wrench.. I need more friends that work on bull dozers

thanx pro.

 

Don't forget to compensate for the .025ft/lb that will be lost with your 3/4 to 1/2 adapter,
