Eaton posi making noise.....

[bryanw1968]

I installed this unit about a year ago and it was fine as I added the friction modifier at the same time. I recently pulled the cover off to fix a leak. I installed Valvoline 85/90 weight and some friction modifier and it seemed fine. After a few months it seemed to leak out again and start making noise. I'm wondering if the friction modifier never really meshed with the gear oil and that is what's leaking out. In any case, last night I drained it again and put some Lucas 80/90 in it. It says on the label that no friction modifier is needed. Now it is making all kinds of noise when I turn.
