Hi, I have a cracked bell housing on my ax15 and saw on eBay a seller posting one for sale. He pulled it off a 4.2 with the ax15 combo. I have a 4.0 ax 15 combo on my 92. Just wondering if anyone knows if this may work for me?
It should. The 6-242 and 6-258 have the same bellhousing pattern (as the later 6-199, 6-232, V8-290, V8-304, V8-360, V8-401, ...) so that's not an issue. Also, I believe that the input shaft length is the same between the XJ and YJ (the input is longer in the J-Series, and probably the SJ.)
I think the "internal" slave (damned thing!) went away for the 1994 Model year, so this should be the correct bellhousing for that as well (it doesn't hurt to ask.)
Yes, you can convert the AX-15i (internal slave) to the AX-15e (external slave); you'll need: bellhousing, front bearing retainer, shift fork, shift fork pivot from the external version. However, it's a simple swap to do. (I say this to point up that you can't just swap the bellhousing from internal to external and call it done - clutch won't work.)
I'd verify that it's the internal slave - if it is, go ahead and grab it, she'll be right.
