Does anyone have a link to the part number for the gray OEM sealant between the cover and the housing? I bought a gasket and some silicone but when I looked at it there doesn't appear to be a gasket there. Is there one from the factory?

I'm ready to put in new 75W-140 and have the additive. Also why is the additive needed if there are not clutches like in a traditional limited slip setup?

I was considering getting an aftermarket cover but after looking at the OEM one it has a ton of surface area with a bunch of really tall fins. My plan is to drill and tap the OEM cover for a drain plug as well.

Thanks Chris!

 

It is nice that you want to use the Ford sealent but it really is not necessary. Most all the gasket eliminators will work just as well. Ultra Gray is what I used.

 

Did you use a gasket too or just the Ultra Gray?

 

Andy if you do it right you can get away without a gasket but then again I am more use to working on trucks so this may be different. If you have the gasket use it. The fins are for cooling, I ordered an extra oem cover because of that, I want to tap it and have it ready to go. For $69 it was worth it.

On the additive I am not sure, did you ask you parts dept about the additive? I have been meaning to ask them if it is the same as a limited slip diff.

 

Ditto. Can get this at almost any auto supply store

 

No gasket needed. The stock car doesn't have a gasket on it. It has a groove cut in the aluminum flange to hold the silicone sealant from all squeezing out.

A small brass brush does a great job cleaning the old sealant off the surfaces.

 

Thanks guys. I'll report back after the job.

 

Include some photos Please!

 

Always.

Here's a couple of teaser shots. I'll swap the fluid this weekend.

Does anyone know if a Torsen needs friction modifier ? Also where is a good place to drill a drain plug hole? I'll likely just figure it out but if the wheel has been invented...

 

Does it need it, i don't know but it calls for it so I would 100% add it. I sure there is a reason. If you drill and tap it, it will be where the two flat areas are. That should work just fine, try to get a magnetic one for the lower plug. You can see both flat areas in your pics. If you can measure out the exact amount of fluid that will be great, add what it calls for. Then you can tell us if it is level with the top plug or below it. I plan to do just that when I change mine.
