Its it possible to put a older jeep 5 speed in a 99 cherokee with a AW4? I know I need a different transcase but will the crank take a pilot bearing ??

yes, it would likely be a different pilot bearing and flexplate... as well as a different wiring harness and computer if I'm not mistaken.

I used an old 258 4.2 originally. The crank flange is the same as a 4.0L. I just switched the 4.0 flexplate over TPS the 258. Just get a flywheel from a manual 4.0L.

"You'll need:

AX-15 -- external slave model preferred
23 spline NP231 (although the NP242 fits, I advise against that)
Flywheel, flywheel bolts, clutch, clutch cover bolts
Throwout arm, throwout bearing, pilot bushing
Manual transmission crossmember and transmission mount
Master/Slave hydraulics unit
Brake/Clutch pedal assembly
4wd rod (to connect handle to tcase -- the length is different)
Driveshafts from a manual tranny
Shifter boot
Bellhousing to Block bolts (at the least, get rid of the torx ones at the top)
dust shields between the tranny & block



Mechanically, that is everything you will need. You'll have to wire in the reverse lights. You will need a manual trans CPS. If you are GOOD with wiring ... you should be able to fool the ECU into thinking the auto is still there. If not ... get a ECU from a manual trans donor."
