    How can you tell if your ten bolt differential is a eaton locking differential or a normal differential?

    There have been posts about jacking the rear end up and spinning the tires this way and that. Most positive identification will be by taking the rear diff cover off, and posting a picture of the thing.

    Well somebody'll post up that knows 10-bolts (I'm most familiar with the 14) but all that spring crap in the middle sure looks like a locker of some flavour to me. I'd say it's definitely not open... past that, WHAT locker it is, you'll hafta wait for someone else.

    yes, they lock and unlock somewhat randomly, and many run them without a problem, but they do end up wasting some pinion gears, like it did to me 2 weeks ago in my 12 bolt.

    Keep in mind, most of the guys that blow up a gov lock are running 35"+ tires and hammering the gas pedal like they were at the tractor pull. Under normal driving conditions the gov lock should perform just fine. The one in my blazer is 20 years old with almost 130k miles on it and works fine. But that blazer also doesn't run tires more than 33" and the only offroad duty it sees are the state gameland roads and some private roads during hunting season. And occasionally pulling out some schmuck that got his 2wd stuck in the cemetery.

    thats definetly not true. because the gov locks are so unpredictable sometimes they last a long time, soemtimes they dont. i had a 89 extended cab 350/700r4, govbomb. 300 thousand miles no problem w/ 33's. my buddy has a 88 blazer, his bomb went off at 75000 miles w/ 30's and it was never driven hard. luck of the draw i guess

    Local law enforcement Suburbans & Tahoes blow out a 10-bolt gov-bomb every 60-70,000km or so. :rolleyes:

    A worn out traction device should default to open - like every other LSD out there. Not self-destruct when its time is done.

    Gov-locks are not unpredictable in operation. They are VERY predictable.

    The problem is the same that has always plagued them...the carriers in the 10 bolts do not have enough beef to hold together indefinitely. The locking action simply puts too much strain on the carrier. You don't see split carriers in the 14SF or FF.

    As stated previous, driven sanely and not used/abused all the time, they will typically last a long time. But as with anything mechanical, you add parts, you increase chances for failure..

    If your running 35"s and not doing any advanced (mud/sand)wheeling it should be fine for a while. If you are looking to go rockcrawling, your asking for trouble. Sooner or later are your going to want to regear the axles for 35"s and a 305 engine anyway. I had 3.08 gears 305/35" tires and the thing was a dog. Take it easy on it and save your money for a 14 bolt FF for when it does go or you advance to rougher wheeling.

    The nastiest drive a Canadian cop car ever gets is a fast & furious 5 minutes of pavement pounding - twice daily - for when the fresh donuts hit the rack at Tim Hortons. ;)
