k so i know...i posted in the grand cherokee section as well, but i just checked and only 18 people are looking at that forum compared to 180 in this one. So....my question is, what axle would have come on the back off a 2000 grand cherokee 2wd auto 4.0? I found one being parted out and I want the rear discs for my xj. He wants 125 for the whole axle.

ok I dont know much about grand cherokees but I'm pretty sure they're all full time 4x4. as far as the axles go there are several different types of axles under all jeeps. do a search in this forum for axle identification, might help a little. good luck

just did a forum search and all i found was pictures of what the diff should look like. I know what they should look like but the axle I am interested in is 1.5 hrs away and without pictures I can't Identify it. I did a quick google search and jpmagazine said it had a dana 44?

K, I found the answer thanks to 4x4 wire.com. here is what they have to say (just in case anyone is curious)

Other Dana 44s

A Dana 44 from any other vehicle will require some fabrication, like spring and shock perch relocation. The Jeep Comanche pickup (MJ) also came with an optional Dana 44 axle from '87 to '90, and is probably the second best choice for a swap. It's the correct width and bolt pattern. The Comanche axle was a spring-under design, however, so to use the MJ axle under an XJ the perches would have to be relocated to the XJ spring-over configuration. For other axle sources, small differences in width can be ignored (with luck) or solved with custom-offset wheels. Larger width differences (full-size truck axles) are prepared by disassembling, shortening, and rewelding the axle tubes to the differential housing.

Dana 44s are available from Scouts and the full-size (Grand) Wagoneers, although the wheel lug patterns are not the same as the XJ. The axle shafts would have to be redrilled, if possible, to the 5 on 4.5" pattern, or new shafts would be bought. The oddest 44 came (comes!) with the Grand Cherokee (ZJ and WJ) and has an aluminum housing. Yikes! Stay away from this one. It's fine for the street, but you'll run into a dead end trying to upgrade it.

A popular option for the new Jeep Wrangler (the TJ... the one with the coil-spring suspension) is the Dana 44 rear axle. Fantastic? Maybe. The TJ uses the same axles (same Superior part number) as the XJ axle. Ron and Vance agree, however, that the TJ uses the same axle tubes in both the standard Dana 35 and the optional Dana 44. If true, the factory Dana 44 option for the TJ is not as strong as older 44s.

I'm barely scratching the surface on Dana 44 information. See Terry Howe's JeepTech.com for more information.

Grands are not all full time 4x4.


More than likely the rear is a Spicer 35 and not the D44a.

Okay, so if it is the d35, does anyone know if the discs will work? I know they work with slight modification from a 94-98 grand cherokee.

The bolt pattern was changed in 99 to 5x5.

Here is a pic of the rear covers...match them up to yours. It could also be a Chrysler 8.25...Tj

I know what they look like. As I mentioned earlier the axle is 1.5 hours away and without seeing it I don't know what it is. The guy says he doesn't know. I asked for pictures but no to no avail. So I am trying to figure out if its a possibility before I drive out there.

I think Country Boy answered my question with the bolt pattern being different.

im going to throw out there that its probably a Dana 35, worth 50 bucks IMO.

country_boy454

They didn't stick the C8.25 in the ZJ or WJ Grands. Only the d35 or the d44a.

i wouldn't risk it, especially for that much.

most, if not all zj's from 95 and up were all disc and mostly d35. you can get the parts from the junkyard for little cash and a coffee. and will fit on all drum/xj d35 and i think can be fit to d44's.

i believe most all wheel drive zj's with the v8 were the aluminum d44. it's crap, stay away from this axle.

country_boy454

They are not all wheel drive rather full time 4 wheel drive (NP249 t-case). 93-95 ZJ V8s came with either the d35 or d44a. 96-98 V8 ZJs came with the d44a.

yeah, whatever. semantics. lol. i was still correct.

country_boy454

I was just stating the fact so people don't get it stuck in their head that they are all wheel drive!!
