    Yes, you can. Most folks around here will tell you it's a bad idea though. For the $$ you might just look into a spool or something instead of welding up the spiders.

    i know im going to get hate mail for saying this, weld it!
    i know its not the right thing to do in a front axle but it works and its cheap. if u are willing to buy a spool why not save a little more and get a lockright locker for the front. i know people run welded front diffs with no complants yet, just broken axle shafts but thats normal with the people i wheel with.

    Don't weld anything like the tech article says too. Front axles aren't welded like that anyway. It is strictly for 14bff's, and I wouldn't even recommend that they be welded like the tech article says too. I run a welded rear like that and it is NOT they way to do it. Weld the spider gears in a full ball for a 14bff. I am about to change my welded rear to a full minispool Jethro lock from what the tech article has. It gets looser over time and the spider gears can crack over time from the repeated abuse of the slack they create from welding it like that.

    In a straight line mud truck a welded front wouldn't be bad but for anything else it would suck. I have seen a welded front in a truck in the rocks here in AZ and it was something I would never recommend.

    harley, he did say for mud only thats why i said to weld it.
    now that i think about it supersizes(shawns) spider and side gears are about done (but i think thats more of a driver thing /forums/images/graemlins/ignore.gif).

    How long can I get out of a welded 12 bolt in a daily driver with 3.07's and a gutless 350?

    My 2 years was applying to harleys 14FF I welded. As for a welded rear, it depends on driving style. I seen then last one trip out, to 5+ years.

    P.S. thats cool the 75 is yours, maybe you will treat it better /forums/images/graemlins/grin.gif jk shawn. btw how is my old 79 k20 doing?

    Ya, I can't really complain. It is not the right way to do it but I didn't know that then. It has worked sofar but I think if I had larger tires then 35" and didn't run them at 40psi on the street it would be worse then it is.

    I will find out soon if any of them actually cracked or not. I am going to the full minispool weld ASAP.

    It has served its perpose well for me sofar. I have a hand full of good hard runs on it at low PSI and it is still working but I need to get the full weld in so the guy at the tranny shop is happy that the slack in the rearend is gone. Otherwise he won't warranty my tranny again.

    Thats cool. I didnt think it would last this long with the little welds I put on like the tech article. Welding it all up is better.

    You are going to severly shorten the life of a 12 bolt by welding it especially on a DD. The fatigue life on a 12 bolt shaft with a welded is going to be alot shorter then a locked rearend. A 14bff axleshaft is much larger then a 12 bolt shaft and the fatigue life is going to be higher. That is why people get away with running 14bff's welded on the street. A 12 bolt might last awhile but it could be short lived also. It is ugly when a 12 bolt shaft lets loose too. Trust me, I know. I have been in a truck when it happened.

    It hasn't really seen a heck of alot of miles since the 14bff went in. Long highway drives to Colorado and back, and some four wheeling runs along with some DD work. It saw most of its miles with the 32" tires too. My truck sat for 3 months while I installed TPI last winter and for another 3 months last summer while I saved money for another 700R4 and rebuilt my 208.

    It has been sitting alot lately which makes me very unhappy so I am now in the process of correcting that.

    For a mud only truck welded is ok, just unlock the hubs after the mud pit is done with.

    For the best all around for the best money I would say lockright. Pretty cheap, easy to install and you can steer alot better then with a welded.

    Whoever recommended a spool, why is that any different than welding it?

    I personally would just wait and get a locker for the front. That's what I did.

    I'd weld the rear without even thinking about it, but the front, leave open until you can afford a locker.

    so u are saying u would weld a 12 bolt c-clip axel?

    yes a spool is just like welded gears but as harley stated welds do weakin over time and the gears can fail.
