Cool friction modifier and leaks

I changed my rear diff. fluid and added the Ford friction modifier several months ago. While underneath today I noticed now that my diff. cover and also my pinion seal are leaking. I checked the level and its still fine. I checked the vent hose and it is not clogged. It must be something in the modifier that is making it leak. Any one else have this happen after changing theirs?

Mine leaked after I changed the rear diff fluid, because I did not torque the bolts on the diff cover high enough.

Changed out mine about 4 months ago and no leaks. Make sure when you put your diff. cover back on you put some silicon sealant on the mounting edge of the cover.

Thanks! I put the "blue" stuff on the gasket. Will try "the right stuff" when I change it again. It is not leaking much but that is a pet peave of mine. Got rid of a chevy that leaked like a siv. I'll be darned if I am going to let my Ford do the same. What about the pinion seal. Isn't it rubber? It didn't leak until addition of friction modifier.

You were prob low thats why it didn't leak. You need to have the seal replaced.
My rear end is leaking also after the work I did. I have a gasket and right stuff ready to go. I'm gonna save the fluid and reuse..

It's also possible that you have too much fluid in as well.
