14 bolt locker with 4 posts and a spring?

[bgreen]

I pulled the diff cover off my 1991 chevy 1 ton 3x3 Crew Cab 6.2 diesel and found something interesting to me. There is some sort of locker inside the 4 pin carrier that uses what appears to be a very large diameter external spring on both halves of the locker. This is not a gov lock. It is a 4 post/pin carrier just like you would find on an open diff. If you put the truck up on jack stands with the tranny in neutral you can spin one tire and watch the sides half of the diff ratchet, and as soon as your try to reverse rotation you can see the half pop into place and lock.

Turning out of my driveway you can feel the thing positively lock, but it doesnt chirp the tires (that could be because of the crappy worn out tires on the back of the truck). Power braking always spins both tires.

I've never seen or heard of a 14 bolt locker that uses an external spring that you can see through the "windows" on the carrier. Any idea what it is? Is it a factor option, or just an aftermarket locker? Is it any good/reliable?

Sorry for the somewhat newbie post, but I've pulled apart a dozen 14 bolts and never have come across this kind of diff.

Sure sounds like a Detroit to me, other than the "not chirping tires" thing.

That's the only 14b diff I've ever seen that you can see the springs on it. Maybe can you take a picture of it?

So the detroit uses a single spring that goes around the outside of the diff, just inside the carrier? I've only installed semifloat detroits, so Im pretty clueless on this one. I'd take a pic, but those windows are pretty damn small and hard to see through even in person, and I have to button the thing up tonight so I can drive it to Anchorage tomorrow.

Never mind I finally found a picture of the 14 bolt Detroit, and from what I can see in there, that is most likely what I have. Sweet!



Now If I can just find a way to change the gears into a 41:10 instead of the damn 41:11

Thanks for the quick assistance scott.

A while ago, I asked on CK5 how to tell a Gov-Lock apart from an open (DL) carrier, and everyone there insisted that if it had a detroit there would be the springs you are talking about.

However, neither the 14 bolt, nor the Eaton H052 that are in my possession, have the spring. Both have DL's and both are identical except spline count.

What was that? You are a fucktard? Yeah, I thought so.

#1 is the 14 bolt- Sure don't see a spring, fella.
click

#2 is the Eaton- again, it must be another of those "invisible" springs.

Thats right you can. Heres mine, on the left side you can see the spring, sort of a bad pic.

whether you were right or not, no reason to be a douche with the rolleyes
I didn't see a spring in dave's pics, I didn't see one when I bought my last detroit equipped vehicle, but I didnt' look that close.
if you can hear the ratchet and chirp on corners, almost no need to crack the cover

He was making reference that the people on CK5 were wrong and that he was right cause he didnt see any springs.
Ill take back my roll eyes
