    I hear people talking about open carriers and such ..... does this look like an open or claosed carrier?

    Its actually open or limited slip, posi, or gov-lock. Not sure if the open actually refers to anything more than the fact that there is nothing in the center of the carrier besides the gears, or that only one axle is driven at any time. Not sure about those axles either, only know the 10 bolts pretty well, and those I'd need a view from straight behind the axle, not angled to the ring gear like that pic.

    Yea, the coloradoK5 personal sites won't allow you to link to a file from another site. That's why I didn't make the URL a link. If you copy and paste it into your address field, it will display the pic

    dyeager535:
    sorry about the pic quality -- I couldn't get a clear shot directly at it. That shot was actually taken by me guessing where to aim. I couldn't get down to look in the viewfinder...lol [​IMG]
    Anyway, in my 10 bolt, which you can see http://Stoopalini.coloradok5.com

    Hey Stoop, there is an easy way to tell if it is open or not. If you look at the carrier itself you can see it is two halfs bolted together. Along the seam of the two halfs you'll see some round shafts, if there are 4 of these it is open if there are 3 of these it is a Gov-lock. At first glance it looks like it is open to me, but the pic isn't the greatest [​IMG]

    Hey man, did you run into your garage door or what? [​IMG]

    Maybe if you could take a better picture from around on the other side of the ring gear...

    There are other tests to identify the diff type without a picture.
    First of all, there are really no LSD's available for the 14-bolt. If it were an ARB, you would have already seen the air-line. That pretty much leaves locker (most likely Detroit), open and Gov-lock.

    With both wheels off the ground, rotate one of the tires. With an open carrier, the other wheel should rotate in the opposite direction (you might have to try it in park).
    With a locker (except Gov-lock), both tires should spin in the same direction. There should also be some ratcheting from spinning just one tire forward or backwards.
    If there a lot of tiny moving parts inside the carrier, it is a Gov-lock. With both wheels off the ground, it should behave just like an open carrier.

    Stoop,

    I didn't take a look at your pic yet, but I can assure you that it is definately a Open Carrier. The carrier of the 14bolt looks wayyyy different than your 10 bolt, I'm sure you noticed that by now. The detroit goes into the 14bolt carrier, while the Detroit for the 10bolt replaces it. Hence, that's why the Detroit is much cheaper for the 14bolt. Anyways, bottom line, its open.

    Thanks everyone, It's definitely an Open Carrier. I guess I just didn't know what that meant ..... so it basically means that it's not posi and power will be directed to the wheel with the least amount of restriction.

    Did I get this right?

    Holding the Camera steady is pretty difficult to do after a 12 pack [​IMG] Also, if you saw my garage, you would realize that I had to nearly stand on my head to get that picture. I guess I could have moved the axle to a better location, but I was done lugging that 500lb monster around for the day ... lol

    Blue85:
    Na, I didn't hit the garage. I backed the truck in, closed the door, then rolled it as far forward as I could get it and blocked it. This way, I have as much room as I can get behind it. I like working on the truck with the garage door down --- nice and warm [​IMG] and the neighbors appreciate it too!

    Thomas.
