dogg rescue Posted January 13, 2017 Share Posted January 13, 2017 I'm trying to swap in a crd93 from a '69 into an '86 the axle splines don't seem to be cut deep enough to slide in. They both are 17 spline, and measure the same size. Anyone ever run into this? Quote Link to comment Share on other sites More sharing options...
kt_Engineer Posted January 17, 2017 Share Posted January 17, 2017 Did you compare the length of the axle-shafts? Both of them could be a 17 tooth splines BUT the axle-housings between '69 & 86 could be different and have different length shafts (the spindles could have changed and as a reason axle shafts could be different). Also there were some changes made in spider in the differential over years, not sure if this could be one of the reasons. Can you also tell me if you have regular differential on '86 CRD93 carrier and switched to a a'69 CRD93 carrier which had a Inter-Wheel Power Divider (limited slip differential?) (There could be a spacer in IWPD that might be causing your problem.) Quote Link to comment Share on other sites More sharing options...
fjh Posted January 18, 2017 Share Posted January 18, 2017 Yes You have to change the side gears in the diff! I ran into this years ago the splines are meant for the older full float axle! Quote Link to comment Share on other sites More sharing options...
