I broke this piece on my driveshaft today on my 75 f100 4x4 longbed/standard cab:



I need to know what it is, where it can be found, and I need to know the correct size u-joint to use (not brand, just the size).

 

would this u-joint work?

Moog Chassis Parts HMG369 - Moog U-Joints - Overview - SummitRacing.com

 

Is this a serious question?

That is a drive shaft Yoke and as for the size of the u-joint u need? Take it to the parts house! to manny differnt variables!!! You can find that part through a driveline shop or a salvage yard.
U can't honestly expect someone to give u a size based on a picture do you?

 

I've had this truck for 2 years, and have never had to anything with this driveshaft, so no I do not know what the EXACT NAME is to look one up. Don't post anything on my threads if you're gonna be like that.

Some people on here do actually know what size caps/joints are used in the trucks. As far as I know, I'm allowed to ask a question on here first before I go out and guess at something.

 

It's called a "slip yoke" and bdivine32 is correct, there are way too many variables to give you the correct part. I did a quick count and the Ford parts catalog lists over 25 different yokes that use either the 1310, 1330 or 1350 u-joint.
Your best bet would be to find a driveline shop and take it to them so they can measure it, count the splines, check u-joint size, etc.
And ouch, that must've hurt, What happened?

 

Would I be able to go to a junk yard and get one?

There's a place by me that does driveline stuff so I'll take it there tomorrow then.

And I have no idea. I used duralast u-joints and they may not have been the correct size I guess and when I shifted and went it just popped.

 

Did you install the u-joints? If so did you use a hammer?

 

Yes and yes. A hammer but I also use a 2"L x a little under an 1" diam. slug to go between the caps and hammer. Has done the job great everytime on my 96 f150. Did it with this truck and you see the result lol.

 

I have done it with a hammer as well when I had no other option or was in a hurry but I wouldnt recommend it. Its too easy to damage an ear of the yoke or the caps on the u joint. I recall u joints lasting not nearly as long as they should when done this way, pressing them in is much superior. The last time I did mine, I took the yoke to a garage and the guy pressed them in for like $20, was well worth it. If you have a big vise you can use that as well, just make sure you dont bind the caps up in the ears.

 

thanks man I'll keep that in mind. Tomorrow after work I'll go look in some junkyards for a complete driveshaft if I can find it. Maybe even the slipyoke. How do you take that off btw?

 

It should have a screw on dust cap on the end of it, just screw it off and the yoke will pull off the splines.

 

Pulled it off to find out it's a 16 spline.

Does that sound about right?

 

Yes, though I have never payed too much attention to them, just pulled them off to replace u joints etc. You shouldnt have any trouble finding one I would think, make sure you dont get the driveline out of phase when you put it all back together or you will get vibration and shorten the life of the joints.

 

When I took it off I don't think it was lined up correctly anyways. It wasn't paralleled with the other end of the driveshaft.

 

That may be why it failed.
