rebuilding a np 205

I have a np 205 in my 79 bronco that has up and down play in the rear yoke and I can not keep the nut tight. So I tore into a spare 205 I have in the shop and once apart the shifing fork was broke. How in the world do you break a shifter fork. Was it caused by abuse. The thing is the gears look fine So should I rebuild it or look for another one to rebuild. I dont want to rebuild the one in my bronco because I dont want it down. I want to rebuild one and just swap them.

Any pictures of the breakage?

If you have some good, clear, closeup pictures of the broken pieces in the cross sections they broke, we may be able to tell you if the failure mode was:

1) Overloading failure
2) Fatigue failure
3) Failure due to material defect/other

This can be done by looking at the metal grain patterns in the failure areas.

I looked at the broken pieces but they were black from sitting in the old grease for several years. It broke the pieces off the end of the fork on both sides. Nothing else was broken so this should be a good one to rebuild?

Guess it depends upon what you mean by rebuild. Doing all the bearings?
Not sure I'd reuse any bearing with larger metal parts possibly
being run through it for a long time (unless you think it was
unusable as soon as fork broke)........

Might be cheaper to source another unit.
