Title: NP 231 4 or 6 cylinder
Post by: Mudpig97 on January 11, 2008, 02:44:17 PM

Okay I have a np 231 t/case from a 4 cyl (21 spline) for sale.  There seems to be no takers so I'm thinking of changing the mainshaft to a 6 cyl(23 spline).  If I get a donor shaft is this a direct swap or will I need something else also(bearings,seals etc.)?

Read here, NP231 into a ZJ, basic theory should apply to other Jeeps:
