U-Joint Install Trouble
I fried the u-joint at the rear axle a few weekends back towing our travel trailer 300 miles.
(I think the mountains on US-30W outside of Breezewood, PA are to blame)
I picked up a Neapco 2-0054BF Brute Force u-joint from Advance Auto Parts
and I am having some trouble pressing it in. It almost seems like the u-joint is 1/16" too big because I can get the snap ring to go in on one side or the other but not both at the same time.

WON'T GO IN:
Anyone else have this problem? Any suggestions? Think a spicer joint wouldn't give me this trouble?
Thanks

Looking at the Spicer chart from the link on at my front axle post, you will see that there is a listing for two different size U joints for the rear axle, totally dependant on the size of your yoke. You will need to measure your yoke, but I think that may be the problem.
Here is the link to the chart. Page 195

Housedad: I think I have to have the larger yoke since I have a V10
Exv10: I did check for this... I had a needle bearing fall down when I was doing a u-joint on my Jeep a few years back... drove me crazy trying to find the problem.
I'm thinking there is something wrong with the yoke. Maybe I did it, maybe the previous owner did it, I'm not sure. (The Ex had 91k miles when I got it) I was able to press the u-joint into the yoke on the transfer case side (of my rear driveshaft) in a matter of minutes.

I doubt if a different size joint is going to be just different enough so the ring doesn't fit, something else is wrong there. Maybe something in the cup, or a bent shaft end, or maybe not in all the way due to a burr etc.

Dana says 3.875’’ or w/4.438’’ , or .563" difference. The pic looks like it's off by the diameter of 1 roller, not a half inch.

<P>U-Joint installed at transfer case end of rear driveshaft with no problem:</P>
<P>Yoke that bolts to rear axle:</P>
<P>Bottom of yokes line up:</P>
<P>Top of yokes don't line up:</P>
<P>Top of yokes don't line up:</P>
<P>So it looks like I need a Spicer C3-2-771! I don't think it would be a good idea to try and bend it back... that sounds like a recipe for a driveshaft vibration.
CORRECTION: C3-2-771 is the casting number... part number is 3-2-1839

Bending it back is no big deal. I have done it a couple of times with no problem. I used a piece of all thread ( or even a stud from a hub) which i inserted through one ear of the yoke. Then i threaded on a a couple of washers and nuts (fitting them between the ears) and proceded to use wrenches to spread the ears apart. A bit of careful measuring and turning produced the desired result.
This may or may not work for you, but I wanted to throw it out there. Good luck.

I found the part online a couple of different places
1:Northern Drivetrain, LLC: Spicer 3-2-1839
2:3-2-1839-DANA CORPORATION-FULL RND FLANGE YOKE
3:Parts
But I had an idea to get the snap ring in there... pressing on the yoke while it was suspended on 4 deep sockets I was able to get it to flex enough for the snap ring to fit. I was planning on using this as a temporary fix until the new part came in, but if you guys think it'll work I'll give it a try!
