? about the Dana rears

Both of the rears (front and rear) are dripping fluild from the covers. Figure I'll pull the covers, whipe out the inside of the unit and replace covers and fill will synthetic gear oil.

Now for the ?.........is there a gasket behind the cover or is there just a ton of RTV gasket sealer?

You'll find that out when you take the cover off.
Now if your asking [should it go back together with or without a Gasket?]
That would be a personal choice. Some Folks do, some Folks don't.
Myself, well I always use one.

RTV only should work fine on the reinstall. Or LubeLocker gasket, they're OK.

Use RTV. It is cheap and works perfectly.

There are gaskets available from Felpro, both my diffs are sealed with them. Autozone for like $2 a piece. Ask for the axle not the Jeep.

if it has a RTV gasket just make sure what ever you go back with is scraped clean, no left over boogers. I do RTV, and use red or black stuff for oil applications, no blue (blue is for water applications) and little goes along way. a continuous bead all the way around an 1/8th thick on the cover or the on axle itself. circle the bolt holes also.

It'll be a bead of rtv. Next time I change my diff fluid I am definitely using a lube locker though.

After years of being happy with using RTV, I've had good enough experiences with my new rear Lubelocker gasket I decided to try that I'm finally sold on them. I have had my rear diff cover off 3-4 times in the past year and the Lubelocker gasket sure makes the process a lot faster. I need to do the front too since it has a very slow every 3-4 day drip, I have a new Lubelocker gasket waiting for it.

Where I am from a lubelocker will definately not be an over the counter item and if I can find it I'm pretty sure it would be pretty expensive. A flat bladed window scraper with some $2 RTV has worked very well for me for the diffs and 42rle. What does a lubelocker price in the US?

Lubelocker gaskets run about $20 a piece. How well do they stand up over time. Is it a change it everytime deal, or are they fairly durable to where they'll stand up a few changes. It's the one thing I dread about taking off the differential cover. I got an F in Art class and it shows when I try to paint my differential cover in RTV. I usually end up with more on my hands then on the ring. Plus scrapping it is just god awful.

I know I said $20 before, but if you need someone to ship it to you, I'm always happy to international ship or AK HI ship for a fellow WranglerForum member. Just figure shipping from 18301 and PM me.

They are essentially, within reason of course, supposed to be a lifetime gasket. I've had my rear diff cover off 3-4 times since installing a Lubelocker last year and it's still leak-free. It has several fine rows of what looks like some type of red silicone around the perimeter which is what actually seals it.
