Locker constantly adjusts

I havenít pulled off the cover to see what kind of locker it is but all of a sudden it is constantly adjusting. I am talking like 3-4 times in a mile. Any ideas?

Need more info to diagnose. What do you mean by "adjusting"? Does it jerk or pull to one side? Try to figure out what kind of locker it is. For example an E-locker is little more than a limited slip and on the other end is something like the ARB locker that positively mechanically locks one axle shaft to the other.

Mine is similar to my old detroit. its basicly a series of clutches and springs. I believe that its a "superior" brand but not for sure. I will try to get the cover off and see.

Yes it steps sideways a little bit when it adjusts. it feels like a I have a low tire or something so i checked that out to make sure it wasnt the case

I'd startwith finding out for sure what locker it is, what kind of fluid it requires, if it requires any friction modifier, then service it.

Only the crappy clutch-based ECTED locker requires a friction modifier. No other lockers we commonly use in our Jeeps require friction modifiers or any other type of additives.

have had 2 Detroit lockers and never added anything. One thing I gotta also mention was I put new pinion bearings and a crush sleeve in it about 6-7 weeks prior to this happening. Itís always adjusted some. nothing like this

Gosh, you have more will power than I do. I would be pulling that cover off to see what's in side as if it was Christmas morning.

I'm still used to early Jeeps, where the Powr-Lok is common. It's a limited slip, and a good one at that.

So I took the back cover off last night and there was no metal shavings but the fluid didn’t look all that great so I cleaned her out real good and looked at the locker. There was no visible brand on the thing. there were some weird engravings that were done by hand that I forgot at home but they most likely won’t make any sense. Anyway the fluid change didn’t help anything at all. it’s just as bad as ever. I will try the additive tonight.. I don’t have anything to lose

No additive will help, lockers (aside from the clutch-based ECTED) don't need or benefit by the use of any additive.

I just thought it cant hurt. I cant see inside my locker so I am not sure if its clutch based or gear. I think gear because if I do a u-turn it squals the outside tire

It can't hurt but it won't help do anything but make more $$$ for the store & additive manufacturer. Clutch-based lockers are limited to the ECTED & odds are against you having one. Standard lockers do not use or benefit by an additive.

Actually, it CAN hurt. Well, it probably won't hurt it, but it may not function properly with a friction modifier, if it isn't supposed to have any. My Dad once put friction modifier/ limited slip additive in a Lock Rite, and it apparently made things a little too slick, and it didn't want to stay engaged.
