Check before ordering: many transfer cases changed parts by year, drive (2WD/4WD) and version. Confirm your unit by its ID tag. Identify by the round/oval aluminum ID tag held under a case-half bolt on the rear half: it reads '231' plus a suffix (231J = Jeep, 231D = Dodge, 231C/none = GM) and an assembly number. KIT SPLIT: input bearing width - 24mm/.940in 'BD50-8' (1987-early 1994) vs 16mm/.630in '6010-N' (1994+); Liberty KJ has its own kit. Call us with your tag and VIN if unsure.
