Slip Yoke Eliminator on the NP-242 Transfer Case
Here is what I found for SYE on a np242.
The kit RE sells for pre-96 231 and 242’s is part # RE1801.
The kit RE sells for post-96 231’s is part # RE1807 (which is probably what you bought).
The contents of RE1807 exist within RE1801 with these parts missing:
FED#473317 ~ SYE Seal (NAPA 16657)
HW1021 ~ 12.9 SHCS MID-1.5×20 (i dunno what that means, probably a metric nut or washer)
RM11500 ~ SYE Bearing / Seal Flange (which i guess is the purple thingy in the picture)
That’s that… the purple thing is probably gonna be the hard one to get. Might be a cap or something for the end of the t-case. I dunno.
