yokes?

[dman1982]

ive got a 84 k10 with a th350 trans, not sure of the transfer case, i broke the yoke to the driveshaft driving home from work yesterday, im having trouble finding a replacement, it has a 31 spline and the guy at jegs said that usally a ford application, wtf??? i really need to get this fixed....asap.

[dman1982]

i forgot to mention that its not the orignal trans, came with a 700, does the year on the tranny matter to the spines? not too familar with these...need help

[bmchevy1979]

Well you are going to have to figure out what transfer case you have. For the th350 the was the np203 full-time (most common) and the np205 part-time (rarely seen). One good indicator if you don't feel like crawling under the truck is by the shift pattern np203 Lo Lock, Lo, N, Hi, Hi Lock(forward to back) and np205 4 Lo, N, 2 Hi, 4 Hi(forward to back).

Or you can identify it by looking at the case Pic#1 np203 and Pic#2 np205 bolted to trans out of vehicle. Pic#3 np203 and Pic#4 np205 in vehicle underside view

hopefully this will help you figure out which transfer case you have and closer to finding the yoke for it

mine doesnt look like either of those, here is a pic of mine, i also put a pic of my tranny pan in there....just incase im wrong.

[bmchevy1979]

Hmm, I have never seen a np208/np241 bolted to a th350 before but I guess it could considering they were bolted to the 700r4

Okay just looked it up and it was only availabe for a few years (roughly 81/82-84)

[dman1982]

ya mine is a 84....it was originally came with a 700r4, it went out and the guy put a th350 in it....which yoke do i get? where can i get it?

[bmchevy1979]

can you post a pic of your driveshaft yoke because that will determine the type of yoke you need

[dman1982]

here it is....from what ive been looking at online, it looks like one that would go to a two wheel drive

[dman1982]

guess that one down view pic didnt come out the way i wanted lol

[ozark]

Looks like the original transfercase and yoke that would have came in the truck. Np 208 transfercase. Shouldn't be hard to find one.

[dman1982]

well it has 31 splines and everywhere says 32....thats the problem im running into....is there a different way to count them? i hate when i order a part and have to send it back

[ozark]

count the spines on the transfercase.

[bmchevy1979]

Well here is the only ones I have found so far http://cgi.ebay.com/ebaymotors/ws/eB...em=#vi-content http://www.dennysdriveshaft.com/p545...spline_fo.html

but you could also do a slip yoke eliminator using parts from a dodge case this is good if you have a lot of lift or out flexing it offroad it keeps the slip yoke from binding in the transfer case

[dman1982]

thats it...the shaft has 32 and the yolk has 31....there is a big space on the yolk....the guy at jegs told me to count the yolk...i was getting super mad cause i thought i might have some crazy jerry rigged deal going on.... http://www.jegs.com/i/Strange-Engine...oductId=744500 would this one work?????

[dman1982]

would i have to change my u joint size with this or is it a direct replacement?

[ozark]

You can get conversion joints if the original size u joint doesnt work.

[dman1982]

bmchevy....that looks like alot of work...and looks like it would exspensive...cant afford that with my usmc salary...i do got about six inches of lift tho...so anything would be better than stock id imagine....with getting rid of the slip yoke what does that do?

[dman1982]

ozark...is it hard to find them?

[ozark]

that yoke in the link wont work you need a long travel yoke for the 4x4

[dman1982]

thanks ozark....any ideas where to find one?

That yoke was used in almost all chevy k10's from 81 to 87, shouldn't be a hard find I have 8 or more around.

[dman1982]

[bmchevy1979]

Either the new ones I posted or used like Ozark suggested any 81-87 k10/20 with np208 or 81-91 k5/sub with np208/241
