Rear end leaking

[kclough]

The rear end on my truck is leaking and I have had numerous people suggest rtv grey or gasket. Which is best and should I buy the oil and put limited slip additive separate or buy the oil with the additive already in it

where is it leaking?

[kclough]

From the pumpkin I just noticed the bottom of the cover has oil on it

have you ever replaced the cover?

just pull the cover let the fluid drai
then get some silicon and seal it up.
wait a while then pour the gear oil in.
i used 75w-140 valvoline synthetic with limited slip already added.
the rear end REQUIRES synthetic.
my cover was pretty rusty so i cleaned it up and painted with rustoleum.

Well you know as well as i do. We sell tons of the dana 60 rear diff covers because of the pin holes that happen in the middle of the cover. They rot out easly

I bought the truck last February. And as I can tell its stock but from what I can tell is the oil is coming from where the cover and pumpkin meets not from pin holes

I sell tons of those covers every month, They rot and are recomended being replaced. Iv seen people put it off and end up blowin their rear end because it drains all the oil. Happened to me once lol. For the cheap $$$ for a new cover it beats replacing the rear end

Alright thanks would OEM be sufficient or should I go with one with fins and holds more oil

Preferrence and $$$ differnce. Rear aluminum diff cover ur looking at $150+, OEM steel, just as good, $45
