Where can I find what specs are on my XJ? I have looked and cant find where to indentify what axles and t case I have. Does anyone know or know where I can find out. I want specs on the whole thing from engine to rear diff. Thanks

 

Usually if you get a hold of a dealer they can get you a build sheet if you provide the vin number.

But if you have pics of the axles I could tell ya... But the front can only be a Dana30. Your Tcase is more than likely the NP231 though.

 

Ill get some pics up. Thanks

 

Sorry it took so long

 

Guess what - you've got a Chrysler 8.25 in the rear

And since yours is a 96, it has the 27spline axles and 3.55 gears.

Way better than a D35

 

thats good to hear. Thanks for the info. What is the front? Is it a 35 or 30

 

The front is a D30. D35's only came in the rear.

 

ok just trying to figure out the front now

 

The T-case is pretty simple to determine too. If you only have 2H, 4H, N, and 4L its a NP232...otherwise you have a NP242.

 

All the transfer cases used on the Cherokee were chain driven with aluminum housings. Command-Trac was standard on XJ models built with 4WD.

* 1984-1987 New Process NP207 "Command-Trac", part-time only, 2.61:1 ratio with low range
* 1984-1987 New Process NP228/NP229 "Selec-Trac", full-time/part-time
* 1987-2001 New Process NP231 "Command-Trac", part-time only, 2.72:1 ratio with low range
* 1987-2001 New Process NP242 "Selec-Trac", full-time/part-time, 2.72:1 ratio with low range

 

I have the 231 t-case

 

actually the 27 spline 8.25 isnt all that much stronger then the d35, the 29spline 8.25 is the preferred axle, this is found on the later XJ models 97+.

so you have a stronger axle then the d35 but not by much until you switch in some 29spline shafts.

The 8.25 should be gone next spring. Planning the "big" lift for next spring
