NP231 input shaft long and short? change?
Ok Here is the deal. I have an 88 yj with a 4.2 and a tf999 auto transmission. NP231 transfer case as we know.
Well I bought another transfer case from a guy that had a slip yoke eliminator in it. It was out of a 1992 yj with and AX15 and a 6cyl.
I read up some and was told they were the same, both were 23 spline.
I pulled my transfer case and first of all trans fluid came gushing out of the transfer case when i broke the seal from the TC to the Transmission.
Is that normal? I think it is , I put it together , but it was dry at the time . I think i just use RTV there when i put it back together. its like a slip yoke inside there right ?( not the issue just curious)
Well now i see that the transfer case i got has a input shaft that is about 5/8 inches long. The transfer case that i pulled out is about 2 1/2 inches long.
they match up and will bolt up and all but its not right. The splines match.
So what do i do now? Change the input shaft from one transfer case to the other? how do I do that?
is it easier to do the input shaft , planetary? or SYE ?
