Sealing Dana 60 chrome cover

[Deleted member 214]

PO installed a chrome cover on the Dana before I bought the car over 15 years ago. Saw small puddle under the rear when I decided to take it out of winter hibernation. Pinion is dry (Yay!) but bottom was damp. PO used a black sealant, no gasket. I have a paper gasket. I'm thing of scuffing the chrome face where it seals to the housing so any sealant has a better chance of doing its job. Anybody got suggestions for which Permatex or other sealant I should use? Gasket, or no gasket?

This is what I use on a rear diff.

With or without gasket, works well either way.

Permatex makes some for gear oil - it has green writing on the package. I've been using that on my rearend gaskets and so far no leaks. Alot of guys are saying how wicked The Right Stuff is. Seals about anything, but is a bugger to get off the next time.

Completely clean the housing and cover with carb or brake cleaner. They must be DRY of all oils.

I use this product sparingly to seal oil pans, and other gaskets that I don't want to leak: http://www.permatex.com/products-2/...-high-torque-rtv-silicone-gasket-maker-detail

A small bead (1/8") around the housing and around the inside of the bolt holes, will do. I would apply to housing, put the gasket on, in the same area on the cover, then carefully install it. Tighten the bolts hand snug, and let it set up. I usually let the oil pans set overnight, then finish tightening them up to the final torque. Allowing the sealer to set up holds the gasket in place so it won't split and squish out.

If its clean and free of oil it will seal no matter what you use. Personally I use a gasket with RTV makes it easier to remove (sacrifice the gasket upon removal).

Because gear oil has friction modifiers that break down normal RTV and cause leaking, this specialty silicone has been tested to OEM specifications to ensure complete sealing. - See more at: http://www.permatex.com/products-2/...-rtv-gasket-maker-detail#sthash.IUNTulj9.dpuf.

Found that link in one of the above posts. Looks like a trip to the parts store for some tomorrow.

I've used General Motors Grey. Mopar makes a Grey for axles as well.
