    Figure might be a good idea to start thinking about buying a limited slip/posi carrier for my 10 bolt for if (ok, when) the Gov Loc decides to come apart. Does anyone know of any that will be really well mannered (IE not super tight) on the street? Truck doesn't see a whole lot of wheeling, and at that, its not hardcore, so a LSD would be perfect. But of course something really good quality...no good to get something and have to replace it 2 years later.

    My Auburn LSD always treated me great on the street. It left me desiring a Detroit off road (which I now have!), but for street use and moderate off roading it was great. I had it for 4 years with no problems, I would recommend it.

    I have the Hi Pro Auburn, and so far have been happy with it. Street, cant tell its there. Off road, its definatley better than open. And you mentioned moderate, so I'll have to second the second post.

    Will work for beer, parts and tools.

    I have Alburn in the front and rear of my Jimmy. I like it on the roar and off road.

    As far as I know, the problem with the Auburn is that it is not rebuildable. When it wears out, you must replace the whole thing and have the diff "setup" done again. Maybe stick with the Gov Loc? I don't know. Me, I think if I were running a 10 bolt I would probably go with one of the "soft" locker inserts.

    Yep, rebuildable would be nice, but "only" 10 years of easy street use or so before replacement won't kill me. I'm going to stick with the Gov loc until it inevitably explodes, taking my gears with it likely : (

    I gotta go with Baddog. I really like my Auburn. Never had a problem until recently. Its not rebuildible, but Ive had it for 8-9 years now. Definately worth the 280 you'll spend on it!

    I've got an Eaton posi in the front. It works great and is rebuildable. Never had a problem with it and i haven't seen it slip too much. - Doug

    How much did the Eaton run you? I wouldn't mind going with Eaton, their designs are supposed to be much improved (read=stronger) than previous offerings.

    I run an Eaton Posi in the front and a Detroit Tru-Trac in the back, they were installed about 3 or 4 years ago. One thing to remember is that even though the Eaton Posi and the Gov-lock are made by the same company, they are two completely different designs.
    I really like the Tru-Trac, and while the Eaton does okay, I would have rather of had another Tru-Trac in the front. It's very streetable and hooks up very good off-road, plus it doesn't have any clutches to wear out so it should last a very long time.

    Please update us when you think the tru-track has worn gears !

    IMHO the only LSD that meets your stated requiremnts is the EATON POSSI, not the gov-lock, no improved gov-lock. These EATON POSI units used to be call by another name, like TOP-SPEC.
    good luck

    Are you thinking of the Powerlock? From what I heard, that is a good LSD.. And rebuildable...

    I think a True Trac would be your best bet if you dotn want a Locker.

    I just talked to the guys at randys ring and pinion (they are kinda local) and the guy basically talked me out of the Eaton Gov Loc. He told me they were the same old Gov Loc that WILL fail.

    He really talked highly of the Eaton Posi http://www.ring-pinion.com

    Eatons page is kind of funny..they compare an open diff, limited slip, and locker and the locker comes out on top..kind of funny since they MAKE a limited slip unit. No word spoken on the site though saying that the unit they tested against the locker was theirs or not. The magazine review was pretty favorable especaially with the wheel in the air, which is where the locker is supposed to be better than limited slip/posi.
