Need Pinion Yoke help

[rdrfronty]

Ok, I just tried to get 4.11 gears installed in my truck with no luck. I was hoping somebody can help me. Stock on my truck, I have a 4 bolt, 24 spline Pinion Yoke. My new gears has a 29 spline pinion. So if it exists, I need a 4 bolt, 29 spline Pinion Yoke. I've tried calling all around and cant find any parts house with any yoke on hand to look at to very what they are. And they want payment before ordering them. I have so far hunted down 8 different part numbers for pinion yokes that nissan uses on our trucks. One of them had bound to be the one I need. If anybody can help give details on this list it would be greatly appreciated. Here's the list----

38210-8S10A = (I think my stock one, but not sure)
38210-8S100
38210-EA000
38210-EB000
38210-EB00A
38210-EC010
38210-EC015
38210-EC020

PM Penski, I thnk he'll know...

I am positive that Spicer makes a 29 spline pinion yoke but accepts a ujoint (not a 4 bolt flange). When I was having driveshaft issues, I am pretty sure that is what I was holding in my hand when I was at a driveshaft shop discussing what my options were in order to get a custom shaft made to eliminate the flange...

If I can't find a Nissan one that will work, then I'll go the route of getting a driveshaft shop try to find or adapt one. Might look into a machine shop custom making one. But I'm still trying to figure out if one of those 8 part numbers I've hunted down will be a direct bolt in. That's what I'm hoping for. It may take awhile, but eventually I'll get the gears in one way or another. But for , it's still pretty cool having my Truetrac finallly.

sorry i didnt answer your pm i was in Moab with limited internet

but your driveshaft is 6 bolt correct?
my opinion get the dana 60 1310 or 1330 u-bolt style 29 spline flange and get a custom driveshaft made up from the carrier bearing back

with the torque your getting now you should get rid of the crap cv on the driveshaft and go to something alot stronger plus the u-joints are easily replaceable

Actually my driveshaft is a 4-bolt with no cv joints. I think my stock pinion and yoke is the 24 spline ones with the bigger splines in a couple places. So I need a 4-bolt yoke with 29 splines for my 4.11 pinion.

I say you just ditch the flange. The flange accepts a ujoint anyway so why not just get a pinion yoke that accepts a ujoint? That will be less rotational weight. The shaft may have to be custom to make up for the distance without the flange...

I might do that if needed. I still am hoping there is a nissan direct bolt in. If not, I will go the custom route.
As a side note, I'm really happy with my Truetrac that I did manage to get installed. My truck really hooks well now. I really have to get on it good to break the tires loose with the truetrac. Just feels really planted. Should be able to lay down some nice 60ft and 0-60 times with it.
I did get a little lead footed at one point today and did a quick sideways burnout though 1st gear, using maybe 90% throttle. I'm trying to take it easy on it for the first few hundred miles. But its really hard .

if you are 4 bolt with a u-joint then you can try and get a 29 spline pinion flange , but im not sure what the part # is

but i think the 4 bolt 29 spline were on the 05's
