Transfer case leak

[Posm]

My Transfer case began leaking some time ago(40K ago) and it never seemed to affect the level of oil in the case, it just made a mess underneath. I finally had a seal put in it 5K ago and it did not seem to help. I am wondering if it may be a plugged breather? Where is the breather?



Thanks

Should be near the top of it and most have a hose going to it. Companion flange been known to leak.

The leak appears to come from between the u-joint yokes. Is there a way that the fluid can pass through the drive shaft and leak out the junction of the male shaft and the yokes? What can I use to seal this?

Probaby needs a companion flange. Its leaking were its welded togather. Its covered under the 7/70 powertrain warranty.

I lost my 7/70 about 32K ago. Is there a way that I could get some other kind of sealant in there. To replace the companion flange, would I replace the shaft and front yoke?

Have a parts man look up the compaion flange only. Yoke/shaft are ok.
