    My 14 bolt has a Gov Loc in it but isn't making too great of noises and is not very smooth when transferring power between wheels. So before it piles up, which it will I'm sure I want to replace it with another Limited Slip. Can't go full locker due to ice driving, had one in my old camaro, trust me ice and lockers don't mix. What options do I have? I have read a little on rebuilding the eaton and something about a powertrax for the govloc diffs.
    Any insight would be appreciated.

    A Powertrax is still a locker.

    If you're heart set on a limited slip Eaton makes a posi for the 14 bolt I do believe.

    If it were me I'd detroit it.

    You can get a rebuild kit(clutch plates and such) from the dealer. Doesn't look like it would be that hard of a rebuild. If you don't want to rebuild it Power Trax No-slip would be a good option more of a true locker but supose to still slip when full lock is not needed.

    This is what I've found on Eatons site, should do it if I don't really have any other cheaper options. I would consider a "no-slip" diff like the one offered by powertrax but haven't found anything for a stock gov loc diff.

    My daily driver is locked in the rear and has a 108" wheelbase. I like it much better than an open diff, I feel that you have much more control.

    /forums/images/graemlins/dunno.gif when I call central4wd.com the guy I talked with said that power-trax made a no-slip for the 14bff gov-lock. /forums/images/graemlins/thinking.gif I will have to do some more checking cause that is what I was going to order when I had saved up the money. If you rebuild yours post up how hard it was and if you notice improvement. May rebuild or weld mine if can't find a no-slip.

    Thats funny, I found that a locker with winter tires would only slide sideways off the line. So much so that I was actually stuck at an intersection waiting for the cars by the side of me to go through before I could go because I took up 2 lanes. Now correct me if I'm wrong but yours is a shortbox with swampers, that would do nothing but slide sideways on ice, I've never been to Il but you must not get very much ice, or your roads are salted & sanded heavily.

    The roads do ice occasionaly here, but nothing like where you live. If it does ice, usually there are enough patches of pavement to get traction on. The ice never lasts more than a day, the state sprays de-icer and salt on the roads pretty heavily.

    you guys are lucky then, where I just moved from (4 hrs from here) they didn't plow the roads for most of the winter so it would build up then turn to ice and you can't get rid of it till spring. Didn't help that they were scared to salt the roads. Hope this new place gets rid of ice quicker.

    Just an fyi, a Govlock is a true locker. A Powertrax no spin acts just like a Detroit. With the conditions you have to drive in I would just stick with the Govlock. Look around in junkyards because they are easy to find for 14ff's and it should be a lot cheaper then a rebuild.

    Sorry, i have to disagree with that last statement, i have a Gov-Loc in the rear of mine, and slips all the time, it will however lock up when wheelspin on one side starts up, then it grabs pretty good, but DEFINATELY NOT locked all the time.

    I believe they are more like a tight limited slip.
    Not the normal limited slip like cars have, but something "tighter" kinda hard to explain what i'm saying though.

    So you would consider an ARB selectable locker as not a true locker because it isn't engaged all the time? A gov lock is like a selectable locker. It is not like a limited slip. A limited slip has the clutches engaged all the time but allows slippage between them when going around a turn. A gov lock acts as a selectable locker. Open for normal driving, but when it has to engage it locks solid with no slippage. The definition of a locker is a device that is designed so when engaged it locks the 2 rear axles together. A properly functioning gov loc does this.

    No they do not lock solid without slippage, i just mentioned this, they do still slip. And a Gov-Loc does use clutches in it as well.

    They lock to a certain degree, then will slip if the pressure is too great, this is why i want to go with a Detroit in hopse of a more "locked" rear diff.

    Just talk with the people who have wheeled with me and have seen my rear diff work,,,,or not work right as it is.

    Now i have seen the 10 bolt Gov-Loc work in a friends truck, that one did seem to lock tighter when the hil climbs were on, maybe because it's a different setup then the 14b, i dunno, but all i know i guess is mine does not work as you are decsribing, it does help but does not lock like you are saying.

    A gov-loc doesn't have a mechanical locking device inside of it like an ARB, Lockrite, PowerTrax, Detroit, etc. None of those use clutches. They use mechanical engagement of metal teeth to lock. However, when a gov-loc is new it will grab very tightly when engaged, but not like a solid mechanical locker. The bummer is that as the clutches wear, the grip slowly fades away. Rebuilding one is pretty easy, but GM gets over $150 for the clutches. /forums/images/graemlins/eek.gif

    Your right they are not locked all the time and neither is a Detroit. They are considered a true locker though. They have clutches to engage them which requires wheel spin to lock and they unlock once you don't have power to it. They are also supposed to unlock at 25 or so mph. If yours slips then the clutches are toasted because they are not supposed to slip.

    A Detroit Locker is locked about 99.9% of the time. The only time it unlocks is when one axle is trying to spin faster than the diff case (as in when turning a corner). The rest of the time both axles are locked solidly together.

    And unlike a Gov-Loc, there is no true differentiation with a Detroit (or Lockrite, Powertrax, etc.) The way that it allows one axle to go faster than the diff case is to completely disconnect it from the drivetrain. /forums/images/graemlins/eek.gif It doesn't have any spider gears at all so you get either all or nothing...
