    I wanna lock my 14 FF before I throw it in my truck. Which is better? welding or using a detroit? I'm worried mainly about it breaking if I weld them together, cuz I don't think spiders are supposed to be in one huge peice. Not to mention the truck is gonna be my DD, so I would imagine a detroit would be better since it does give a little if you aren't pressing the gas. Any input?

    Anyone ever try to weld up a grenade-lock in a 14 bolt?

    I'm seriously consittering an ARB air locker. I like how it's a standard rear end till you hit a switch on the dash.

    This has been talked about in other threads but yes, I completely disassembled my gov-locker and welded the crap out of it. I enjoy the predictability and reliability (and width) of the welded rear, van 14BFF in my ride.

    Unless you know something I don't, the only locking device for a 14BFF is a detroit locker. I have just researched it through a 2002 catalog.
     
  8. the detroit if you got the money, but im sure a welded 14 bolt can take some abuse. but watch ou tread dissapear. if you are willing to get a locker, then why not go in betweena nd get a spool? they are cheap and stonger than both.

    I'm just curious because I have one with a Gov-Loc in it and I'd rather weld it together before it becomes a Grenade-Lock. One of the local guys told me it's impossible to do it but I'd rather trust you guys. Besides, how much trust can you put in guys that balance their tires by cutting off lugs?

    A spool will eat the tires just like welded will, and I'm pretty sure a spool for a 14 bolt is not availble yet. If it is...post a link please.

    I also don't think there is a spool for the C14FF, and there is definitely no ARB. You can't weld a gov lock in a C14FF but, they are very strong and are not known to blow like the gov-locks in smaller axles. This is hear-say but seems reliable. I have the Detroit which is super easy and cheap for the C14FF. However, if mine had not come with the Detroit, I would have welded it without a second thought. Problems associated with welding the diffs of smaller axles do not (in general) apply to the C14FF...

    This is off topic but there is a selectable locker coming out for the C14FF - the Eaton "elocker". Same idea as an ARB except they're electrically actuated instead of by air and Eaton's supposedly going to make one for the C14FF (and 10b, 12b, 14bSF and then others).

    Eaton has a history of OEMing stuff for GM so I guess that's why they're bringing the elocker out for GM axles first, to be followed later by ones for Dana and Ford axles. The elocker will be in the new Hummer H2 in an AAM axle.

    Here's the pinch tho - apparently the elocker won't be available until sometime in the 3 quarter of this year and who know's what the price will be. The price will probably be competitive with the ARB and Oxtrax type units (even though it looks like it's a lot cheaper to produce). Since your axle is already out of the truck you probably won't be able to wait for this puppy.

    I think the April Petersen's had an article on it and you can surf Eaton's low-content traction site: http://www.traction.eaton.com.

    No I don't work for Eaton! If the elockers get a good rep in their first few months I want put them in my C14FF and (ack) 10 bolt. Yeah, yeah, I should put in D60 first.

    I know I saw a 14BFF spool in a mag add...it was a mini-spool and was a bit more then $200. I wish I could remember who it was...

    I welded mine and the only thing I don't like about it is the increase in turning radius. I now have to plan ahead for tight turns and it is sometimes a 3-point turn to get into a parking spot. My truck is not a DD so it doesen't bug me much. If mine was a DD I would put in a Detroit.

    Why can you not weld up a gov-loc 14 bolt. Cause mine has been that way almost a year. I took it apart through away all the little counterweights and junk and welded the piss out of it. I run 38's hard and have not had any problems

    Butch, I agree with you. Why can't you weld up a 14BFF gov locker? Mine seems to work just fine. I guess nobody saw my other post. I enjoy hearing "You can't do that" from some others....

    You know, I saw the ad for the 14BFF mini spool too....just don't remember who was advertising it. I know it was not in Peterson's or 4Wheeler....

    mini and spool are 2 different beasts
    welded is as good as a mini, perhaps better IMO

    Ok, I guess I stand corrected. I should have said that I don't see it as an option, but then, I've never been inside a gov-locked C14FF. Like I said, that info was "hear say". My understanding is that they have a 3 cross shaft design rather than 4. Still stronger than smaller axles but, not as strong as the open C14FF with 4. Also, you have to weld it with the case open, there is no access port like most other carriers have so that you could weld it in place. I can easily understand how it would be done to an open case as Rene and Laura have shown. Just fill the some of the voids on the spiders, slide them into place, button it up, and done. I do not understand how a gov-lock could be welded with the case open so that it could be closed up and hold up under hard use, but that's probably (obviously) an artifact of my lack of knowledge on the gov-locked C14FF. If you are both running welded gov-lock cases, obviously I was wrong and I apologize for representing incorrect info. Sometimes it's all to easy to jump from "I don't know how it could be done" to "it can't be done"...

    I don't remember which mag the ad for the mini spool was in, but the company is Drivetrain Direct. I'd personally rather run a full spool, but I don't think one is available yet for the 14FF.

    Why do you think welding would be better then mini-spool?...asside from the obvious $$$.

    I did the welded them up because I am cheep, they didn't make the spools yet, and I didn't want the slop in there with my t-case mounted e-brake.
