Chrysler 8.25 - LSD identification

[XJ_NorCal]

Could somebody tell me if my rear diff has an LSD or not by using the photo below...?

 

[RCP Phx]

By what I can see, I would say no!

Looks like it is. The 8.25 LSD and open carriers are shaped differently. Check the glove box for a warning label.

Yes, Limited Slip. Axle tags and glove box warnings are often long gone.


Open Diff on LEFT - Limited Slip on RIGHT

Sooo it is? What would be the easiest way to confirm. My diff cover is installed again so preferably something that doesn't require removing the cover again.

Google pictures for yourself ?

Jack the back end up and try to spin a tire. In other words, does it actually try to limit slip?

I agree with Tim & Two Door and the picture. Squarish carrier is LSD. Rounded one is open.

 

[XJ_NorCal]

It looks like a Limited Slip Diff according to the photo. I'm going to jack it up and confirm today after work.

Ok so I jacked up the jeep and turned the wheels by hand while in park and it responded like an open diff. I then turned the wheels while in Neutral and also in Drive and both responded like a Limited-Slip Diff. Which is correct?

You have a Trac lok friend. Good unit when they work, pretty good with stiffer clutch packs.

 

[Tim_MN]

The clutch pack wears out and the Limited Slip becomes an open differential. You can replace the clutch packs and restore the function.

Good to know I've got the factory Trac-Lok but I've been driving it for the last 2k miles without friction modifier. At this point do I even add it in?

I'm going to re-gear, install chromoly shafts and add a selectable ARB locker this winter. I was planning on installing the locker in the rear but if all I need to do is replace the clutch pack for the LSD in the rear then maybe it makes sense to install the locker on the front axle.

 

[Tim_MN]

You can install a lunchbox type locker in a Limited Slip differential. They are not many that fit, but they do exist.

Eventually I will install selectable lockers in the front and rear. To save myself a little coin I'm only going to install 1 selectable locker at the same time I re-gear and upgrade the axle shafts. I wouldn't install a lunchbox locker in the rear since I'm going to add a selectable locker in the future.

It would seem the smart play would be to install the first selectable locker on the front axle and replace the LSD clutch pack in the rear at the same time I Re-gear and upgrade the axle shafts. I'll likely install the 2nd selectable locker in March 2020 (tax season).

Can anyone tell me what auto lockers do fit the lsd carriers?
Thanx

 

[Tim_MN]

Which axle, Dana 35 or Chrysler 8.25 ?

Chrysler 8.25 lsd.
I have the rear diff stripped, and just about straighten the housing, 1/2" each side out of alignment.
Diff case has moved forward after being T-boned.
I went all out and fab'd a torture rack.
Anyhow......
The Trac lok center in my 8.25, the clutch packs need replacing. Are these the same replacement parts used in any of the dana Trac lok centers?
