08-10 rear diff cover

I just picked up an 08-10 diff cover for our 04 Excursion. I took it out of the box and noticed that it had a groove machined in it that looked like a gasket should have come with it, but none did. I was just planning on using high temp gaska-sinch on it when I put it back on. Is there a gasket I need to go track down, or am I good to go?

Good to go, I used RTV when I put mine on my obs.

awesome....thanks for the info. Now just gotta go get some gear lube and I'll be set.

agreed no gasket used

Grey rtv is what I used

You also need longer bolts.

You could use rope in the groove with rtv. Works on the big trucks. Good insurance.

RTV works just fine. If you need some hardware I have a couple extra sets, I bought them in bulk.

Think Im gonna pick up the 08 diff cover this week...

One of the first mods I did. More more leaky rear cover

Do the 08 and up dually covers look the same? And will they fit on my dually?

If your rear is a D80, I have an 08 D80 cover.

PM sent.

I modded mine for a diff temp sensor...

Joe...that looks nice.

Can anybody tell me what the capacities of the rear and front diffs are?

:rockon:

I went to our local Fastenal shop, picked up my 12 SS bolts and washers for $7.18.

Thats where I got mine years ago... Thats like a candy store for me.

This should fit the 10.25 as well right? What about the front, is the 08 front nifty as well?

not as nifty
