That is not in any way a limited slip differential. In fact, that isn't a differential at all... its a homemade spool.

Anyway, I have 2 Chry 9.25" rear axles both with over 100k miles and neither of them show any signs of wear at all. Here is one of them while I was rebuilding the limited slip diff with new clutches and putting in 4:10s (this one had about 130k at the time this picture was taken):

pardon ignorance, but what is that clock ring for? The speedometer?

 

That is too a limited slip differential. It's njust that rather than clutches, the limited slip is controlled by how much the axleshafts are willing to twist before snapping.

 

Everything in my pic is original with 216,000 miles I just thought heck might as well help out the traction department since its my mudder

Its a Tired ole 4.0 l6 with 216,000 miles it isnt going to snap them axles. I know a guy that did the same thing in his 94 silverado with 6in of lift and 35's and he drove it on the road all the time never broke loose on him.

 

See. It's a limited slip. They must be allowing alot of twist! :P

 

Now all I need is my lift and tires and ill be set of coarse my dad doesnt like the the back of our property has a bunch of donuts done in the grass I wonder where they all came from?

 

It's a tone ring for RABS. On the newer trucks (2nd gen) it may also be the speedometer, I know on 98+ Rangers they made the tone ring also the speedometer in addition to RABS.

 

so ABS only engages if both axles lock up? I was under impression it worked if either axle was locked up.. Would explain why mine doesnt kick on when only the right rear starts chattering.

 

Yep, that's the design flaw when using a ring gear mounted tone ring.

 

Anyone else have any pics?

Here is a youtube link to the sound I hear when the axle is warmed up:
