NP205 Output issue

Got an NP205 issue? Maybe? It's a ford 205 so I figured I'd ask the Ford guys.

I Googled and searched on here and didn't find my answer.

I just got my new 1350 CV driveshaft and flange for the rear of my Bronco. After installing the Flange on the output i noticed i have about an 1/8 inch or so of end play in the rear output shaft. Is this normal? Or do i have a problem?

I don't remember having that much play with the old 1310 cv yoke, but then again i wasn't really looking for it either.

All 205's are the same, gears are interchangeable, general tech would have been fine. Something sounds off - they are easy as sin to work on, my dad and I took one apart for the first time with the aid of 3 or 4 cocktails and we figured how to put it back together just fine

End Play

Didn't think it was right. Guess i'll pull it apart and see what I screwed up.

Thanks for the help

Never had mine apart, but here's a diagram that may be helpful.
Does the new yoke bottom out against the bearing? If the splined length is too short it may leave a gap that will cause play. Check if it's the same length as the old one.
The snap ring holds the bearing between the retainer and housing. The yoke pulls the shaft against the bearing.

If you remove the output assembly, there are needle bearings between the input and output shafts that will fall out and need to be rounded up.

Well, judging by your diagram and what I can remember, I am almost positive I got it back together correctly. I'll compare the length of the new flange against the old yoke when I get home. Thinking maybe the new flange is just a tad bit long.

Ya, your right. I was thinking backwards as usual.

Well, the flange and yoke measure out the same. Put the old yoke back on just to double check, play is still there. My best guess now is I must have forgotten a spacer between the input and the output shaft. Great, get to tear the whole thing apart again and haven't even driven it yet! Oh well, it's my own damn fault

do you have the snap ring on the output bearing? proper gasket under the output bearing retainer?

the yoke should lock the output bearing against the shoulder on the output shaft, and the bearing retainer should hold the bearing in the case. excess play will be something amiss in this area

there are a few inaccuracies in the diagram above. one of which the output bearing is shown backwards (snap ring groove and snap ring go toward the rear). the fork is also shown backwards.
