    Depends on the year of the axle, not sure what years they changed. They were either cast or stamped mild steel.

    99% sure that the spring pads are mild steel. Along with the tubes. The housing should be the only part that is cast. As far as welding goes, I'd use a MIG welder. Or if all ya have is a stick welder that is capable of DC current, use 7018.

    Well...they are either stamped steel or cast...it should ba easy to tell the difference. I have a 77 and they were cast iron and that is most likely what you have. I made some new ones out of 2.5" .25" wall square tube (because no one that would weld them on for free would touch the cast). You can also buy new stamped ones but they just look wimpy for such a tough axle.

    I have always thought the perches were cast pieces.

    Be aware of the change in the perches on the 14FF's. All 14FF's up to '84 have the cast perches, and in '85, they changed the perches to the stamped steel, exactly like the 10 and 12 bolt rear axles. /forums/images/icons/wink.gif

    Just an FYI Wes

    My 14ff is out of an '85 1-ton & has the deep-pocketed spring pads; the ones I'm guessing are cast. Either way; they're not like the ones on my old 10-bolts

    Send me pics, too. I can tell you which you have. /forums/images/icons/wink.gif

    I still stand by the stamped steel perches in '85 theory.
     
  11. can someone explain to me the difference between cast, mild steel and stamped steel? which is stronger, why and why cast is hard to weld on? thanks

    Mild and stamped steel are the same thing. Easy to weld and cheap to make. The cast perches shouldn't be a big deal either...I'm pretty sure they are ductile cast. If you look you'll see they are welded from the factory. I'd prefer the ductile cast perches as they would be a bit stronger. Ductile cast doesn't require any real special welding procedures or any special rods. We used to use ductile cast for some oddball parts at a place I used to work at. We used MIG on em...

    FYI Jason normal cast iron requires special welding rod and procedures to weld properly (T-case adaptor would be a good example)

    Brian, I got your e-mail.

    Your pics show the 14FF you have, to have the cast perches. Your axle is the '84 or older one.

    The stamped steel perches look like the 10, 12 and 14(SF) bolt axles. The 14FF stamped steel perches are a lot thicker though.

    10 and 12 bolt perches appear to be about 1/4" thick. 14FF perches appear about 3/8" thick. You can see the difference.

    My '85 K30 has these stamped steel perches. I can get pics if anyone would care to see them. /forums/images/icons/wink.gif

    Thanks Wes

    I can't argue on the year cause I didn't actually pull it from a truck. It was shipped to me rebuilt with "1985" on the invoice & tag. Just going by that but that doesn't mean you're wrong! /forums/images/icons/smile.gif Hell! I'm happy just to have a 14ff!! /forums/images/icons/tongue.gif/forums/images/icons/laugh.gif

    Thanks again for the help

    No problem. /forums/images/icons/wink.gif No big deal either. Like you said, just be happy you have the 14FF! /forums/images/icons/wink.gif /forums/images/icons/cool.gif

    IMO, the spring perches are the least of your worries with these axles. I have not seen nor heard of one stamped steel perch going bad on any 14FF.
    Nor have I heard of any other problems with these rears, too. /forums/images/icons/cool.gif

    Interesting...I guess I could have re-used the stock cast ones...I like the ones that I made though and was able to move the axle back 1" in the process. Oh well...live and learn.

    If anybody is interested, I have spring pads for 14 bolt's. I am also in the process of making them for the 1/2 ton axles as well. They are made of mild steel and are solid. These have to be the strongest looking spring pads that I have ever seen. They are machined to place the leaf spring aprox. 1 inch above the axle tube. I can also drill them in the center, 1", or 1 1/2" back so that they can be used to relocate the axle slightly. If anybody is interested in a set, PM me. The price for now is 40.00 a pair plus shipping. These things weigh in at about 5 lbs. apiece, very stout. I will post some pics of them as soon as I can.

    OK Wes

    Just a little update to say "oops" /forums/images/icons/blush.gif & to re-verify that you've got your facts straight. /forums/images/icons/wink.gif The invoice says both axles are from a SRW '85 1-ton while the tag on the 14ff said 1980 when I double checked last night! /forums/images/icons/tongue.gif

    Thanks again & you remain "THE" K30 man! LOL! /forums/images/icons/laugh.gif
