Does anyone know where I can purchase service and parts manuals for the 392? I checked tech authority and couldn’t find anything.
 
There are no paper manuals available anymore. You can go on Mopar's website and rent time for the section of the manual that you want to see.
 
I have one, do you need me to look something up until you can find one?

Front and rear differential capacities if you don’t mind. I know the fluid type. I want to know how much. I have read 1qt in front and 2qts in rear.
 
Just changed mine:
Front Axle is M210 ~1.3 Qts
Rear Axle is M220 ~1.6 Qts
Ok. Thanks. There is info all over about pints and that conversion was like 1.09 qts and then I read just 1 qt so I was all confused. Where did you get a service manual?

I've not gotten a service manual yet, but do want one. Current plan is to wait until an event comes along that requires me to get one, then ponying up and paying Stellantis for access.
 
So how are you sure that the capacities are correct?

By measuring how much it took to fill each diff. The fill level on the diff's is to the bottom of the 'fill' hole.

Attached is the Dana spec for the rear axle, showing 3.06 pts for the electronic locking diff. 3.06 pts is 1.53 quarts, mine took just a shade more before it started to run out of the fill plug.

Looks like it's available now:


Has anybody used ALLDATAdiy?
I have used Alldatadiy for half a dozen vehicles over the years and generally found them to be very good WHEN THEY HAVE the vehicle. I have a 2013 Audi Q5 and it took them years to get that. And currently for 2024 Jeeps they only have GC - no Wranglers of any flavor. The biggest problem with any of these online manuals is you don't really know what they are missing until you go to do something and find out it is not there - I cannot recall any specific instance but I have had it happen although I got around it by doing an old fashioned internet search.

Just before Thanksgiving I was doing something on the Wrangler and bit the bullet and bought a Mitchell1 DIY subscription - they have the 2024 Wranglers and I have not used it extensively yet, but if anyone is getting tired of waiting on Alldatadiy, Mitchell seems to be comparable. It works differently and took a while to figure out the navigation but so far the content seems solid.

2 plusses to Mitchell I found are it is less expensive for a multi-year subscription and the Wrangler one at least included all the engines - IIRC Alldatadiy makes you specify the engine and you only get that data.

Hope this helps - usual disclaimers, I have no financial interest in either product, just passing along my experience.

Thanks for sharing, much appreciated.

To be clear, it seems that Alldatadiy is available now for the 22 and 23 392, but as @RP1 pointed out, not for the 2024 (yet.)
