T-case output seal

red91 · Nov 6, 2004

Just put a new one in to replace the one that has been there for 113k.

NOW...the damn thing is leaking worse than before, from what appears to be around the rubber overlay not the metal edge.

WHAT COULD POSSIBLY BE WRONG???

Right part ? Yes I puretty sure since it looked, within reason, just like the original.

Did you use sealer between the seal and the aluminum tailcone casting? You really need it.

Be sure that your t-case vent is not plugged. I changed out 2 seals on mine before I found that my vent was plugged causing excess internal pressure at operating temp. After clearing the vent my leaking seal quit leaking.

The vent is somewhat on top: look for the rubber hose that goes from it (on top) all the way into your engine bay.

does not appear to be plugged. I bet sealer is the issue here,my old seal was degraded and bad, never had problems before that. Always held proper amount of fluid with no problems.

What kinda sealer????

Did you check that valve thingy at the end? Cuase that might be what's plugged or not operating right.

seems to be ok remi, but what do I seal it with? permatex?

I use permatex 1B for that type of seal. It is a brown hardening type sealer. I haven't had as good luck with the silicone type sealers on seals.
