Rear differential center

[cherokeekid]

I've searched everywhere I can think of: do the rear 9" and 9.5" share the same center section? I.e. 12 bolts to the housing?
Is there another way to visually determine which one? The dealer was not able to confirm.

Probly look on the ASA program and compare that way.

ASA? I can't believe i can't find a pic online

I have both sitting in my garage, I'll snap a photo at some point, won't be tonight.

Awesome thanks!

Pictures will help a lot, so it sounds like they do look different?

Hub spline count is what will do you in. 9.5 has 2 more splines iirc.

 

[cherokeekid]

You mean shaft spline ? Can a 9.5 have 31 spline or 28? I'm looking at a 2000 sport (need the r&p) I know it's 4.90. But it's a 3.0 I can't remember the spline for sure but I think 31. The best I can tell the center looks the same as the 9.5 I have (12 bolt) mounting the chunk to the housing

As far as I know it only comes in one configuration. The shaft is slightly larger so it should become apparent that it won't fit.

Not worried about the carrier or shafts. Just the ring gear diameter. From what I can tell 9" had 10 bolts and 9.5" had 12 bolts mounting then center section to the housing, but want to confirm before I rip it out

 

[cherokeekid]

Ok so this is a 9.5" does the 9" look the same? Do both the 9 and 9.5" use 12 bolts to attach?

IIRC 9" is 10 bolt.

Sorry for the delay, both the centers in my garage are 9.5" ring gear (one is a locker, the other isn't) - forgot about that. I'll need to take a look under the '93 at some point.

Thanks
The number of bolts for the center work, I've heard 10 for the 9" but want to make sure before I crawl under and yank it out
Can anyone confirm the bolt count?
