Which rear axel do I have?

[Corytrade]

So I am doing all the fluid changes in my Liberty (05, V6, came with tow package), and I am not sure which rear axel I have. The identifier is missing on the differential. The Haynes manual says the model 35 requires 75W-140, and the 8.25 rear axel requires 75W-90. I do not do any towing, even though it has the package. I just jacked it up and did a LSD test, and it is not limited slip. I looked to see if there is an identifier from the VIN, but couldn't find any info.

Chrysler 8.25.

Thank you sir. Is it the standard rear axel with the V6 and/or tow package? Just wondering how you knew.

I don't remember exactly the rhyme or reason, it's been so long, but I do know that every 3.7L and 2.8L CRD got the Chrysler 8.25 for that particular model year.

With Your Vin Number walk into any Chrysler Dealer & obtain a free print out of the Jeep's options/build list.
It will not only tell you which differential you have open or trac-lok, but u can see all the good stuff from fogs to alternator to well..everything!
The standard is 8.25 corporate axle and I use Lucas gear oil. 75w-90 is standard if not trailer / pulling.
Here is what a trac-loc looks like inside, and it does require the Limited slip Chrysler additive as well.
Adding a limited slip additive will not hurt an open carrier if u really are not sure.

8.25, very few of the early model 02s had the 35
none after that
Use regular dino gear lube, no need to spend a lot of $$$ on the fancy named diff fluids. Dino gear lubes stick to the gears much better than synthetics etc
You can run any of the weights mentioned without issues
