Hopefully that will not leak. By pushing it hard you could have damaged the seal, unless you were turning as you push.ok I removed the flange from my old (green one) 203 to put on the one I want in my truck but the flange doesnt mate flush with the case. The Ujoint style works on both but the flange only goes flush with Tcase(green) it was removed from

I would have at least smoothed it out a little so it doesn't wear out the good seal you have on this tcase.
The old one is all but gone, that is why it fits so easily
No, I just gave a slight twist and push and it went in. I really wasn't forceful at all. It went right into the green case it came from. The black one you can see the seal is newer

That flange yoke looks like it may already have a speedi sleeve on it...
I would spend a few bucks and find a new one....that one is chewed up pretty good...

np203 front output seal repair sleeve .
It slips over the outside diameter of the yoke
and creates a new seal surface for the seal to ride on. Look at yours closely and make sure there isn't one installed already.
post up a close-up picture of the yoke where the seal rides...
I may have a good one, but I would try the one you have first, if it leaks then you can change it, it's not the worst thing to change in the truckI looked for that flange and found nothing online used or new.

I'm pretty sure there is a speedi sleeve on it already....see that super thin ring that is seated up against the big washer looking thing on the flange yoke? that appears to be an old sleeve. Someone probably attempted to stop a leak in the past.
Worst case, cut/remove the old sleeve and install a new one...
