E4OD — someone has to know something??
considering how many E4ODs must be in circulation, i'm surprised how hard it is to find any info about them online, even from driveline specialty shops...

anyway, i'm trying to figure out which slip yoke i need.
i've got a '95 RWD E4OD (purportedly from a lightning truck). i've got the rear driveshaft (will be shortened) and slip-yoke from a '95 F150 4x4. various sources online indicate that the slip yoke is the same between the transfer case (4x4) and the tranny (RWD) models.
my problem is that this yoke won't install past the backside of the brand new seal i installed (and barely goes in the front boot of the seal).
according to a local driveshaft shop, i should be using a yoke from a C6, which is also 31 spline but measures 1.685" shaft.
but when i search online for E4OD yokes, they show a 1.886" shaft (which is what mine is). however, the confusing part is so far all of the E4OD tranny seals which i've found online (including the one installed) are for a 1.685" shaft (so i'm not crazy that my yoke won't fit past it).
so... do i have the wrong yoke or the wrong seal??? i was hoping the wrong seal (cheaper), but i haven't found one yet that will fit a 1.8 shaft, but before i go and order a $75 1.6 yoke i wanna make sure it would work in this application (despite listings saying it is too small).


any educated insight would be much appreciated, thanks...
1.668" seal for the RWD trans (find it under Auto Trans).
1.886" seal for the 4WD transfer case rear output seal (find it under Driveline, then Transfer Case).
So maybe the slip yoke for 4WD really IS larger? Easy test, pull out the new seal you just installed in the extension housing of your RWD trans, and THEN try slipping the 4WD yoke in. If the 4WD yoke really IS bigger, you will know! All it will cost you is a new seal to find out.
