OEM Rubicon Locker Study

A forum member recently sent me his old Rubicon e-locker.
Here is a quote from the owner:
"...when wheeling in tough areas (sand, mud, rocks &tc.) I put the locker in for a while & then take it out, put the locker in for a while & then take it out, repeat. So, I've used it a lot. My Jeep has 105K miles & I'll bet 15-18K of that is off road."

It has seen some good use. The differential and dog clutch show very little wear.
The ring in the 3rd picture below looks quite worn, leaving a small lip at the inner diameter
That could be the cause of locker ratcheting.
Installing a shim to make up the difference has at least temporarily fixed it in some cases.




Here is a look at how the Rubicon e-locker works.




























See this great video to review how a regular differential works:

Wahoo! That answers several of my locker questions. Now, this is a technical thread.

One of the best explanations of a locking differential I've seen, thanks for putting it together.
