bkdrocks Posted February 4, 2010 Share Posted February 4, 2010 Can some one tell me the correct pilot bearing used when swapping an AX15 for a BA10 into a 1988 4.0 Renix motor.. Please!!!! Cross member the same on both transmissions? I guess you figured out I stuck with a manual transmission!!! Quote Link to comment Share on other sites More sharing options...
JeepcoMJ Posted February 4, 2010 Share Posted February 4, 2010 are you using a mid 89-90 ax15, or 91+? Quote Link to comment Share on other sites More sharing options...
comanche09 Posted February 4, 2010 Share Posted February 4, 2010 Mid-89 to 90 AX-15 is the same (I have a 90 sitting in my garage) 91+ you'll need a pilot bearing from a 73-75 CJ5 304 V8 w/3spd, around $4. Crossmember is different, AX-15 has notch where the trans mount goes. You may or may not have clearance issues if you re-use the ba-10 crossmember. Don't forget you'll have to move the crossmember back to the last set of holes, you'll need to tap them (10mm x 1.5 tap) Quote Link to comment Share on other sites More sharing options...
