so im gonna change the rear diff fluid but i cant find any mention of a gasket... i even called ford and they didnt have a part# on it... anyone know where to get one?

 

If your talking about the rear end diff cover, i believe there isnt one.

 

ford doesnt use gaskets on our differentials and you dont have to either.

 

Nope no gasket, just use some RTV when you put it back together, insta gasket.:) Its what we did when me and bob did my diff and his.

 

Yup. What they said.

 

ok cool ill go get some tonight since i need a new hose for the blazer too... i really need to do this before i drive the truck to delaware on thursday

 

i used ultra black on mine and ryans diff, but i think ford uses gray from the factory. it really doesnt matter that much on the diff

 

Try lube locker if you don't want RTV, they make a nice gasket for the 8.8.

 

holy old post accually this reminded me that i need to change my amsoil oil filter

 

The trick with the RTV is to run a bead on the diff cover, and let it set up for at least 2 or 3 minutes before you put it on there.. if its too soft and you torque the bolts down you'll squeeze too much out and it won't make a lasting seal.

 

there is a gasket but is isnt used if you go to autozone/pepboys they do have a gasket for it. it is not required but I am highly nerotic and have a gasket and rtv....so ya...

 

I used a gasket & RTV, guess I'm a bit ****.

 

Hey guys, just a quick somewhat related question. I'm in the middle of replacing my rear diff fluid and was about to reassemble but noticed my Haynes manual does not list the torque specs for the diff cover bolts. Does anyone know the torque spec for these bolts. It's a '97 4x4. Appreciate any input. Thanks.

I was going to guess 35-40 ft-lbs. Thanks for the help.
