Default Front axle sealing with 3/8" different covers

So I currently have a Dana 60 front axle with a BTF diff cover. It's flat as flat, checked many times with a straight edge.
I can pull the cover, seal it with black/blue permatext, right stuff,and anerobic sealant. It stays sealed until the first descent hit to the diff cover then poof. ..leaking again, a whole diff will drain in about a week.
How does everyone else seal their junk? Would a actual gasket work better?
Thanks GL4x4...

I use grey international/ ford silicon comes in a caulk tube. Are you useing rtv and anaerobic sealer together? If so that may be your problem.

Both mine are leaking as well. Not that bad, but it leaves a spot a good 3" diameter after a week. Im using the black rtv, stock covers. But yes, a good smack and they leak, never tried an actual seal...

I use gaskets. They seem to do pretty good but I have to occasionally tighten the bolts.

I use a gasket on front diff. Being the rear is custom shaved with a custom ruff stuff cover I use ultra grey. I think I went 3 yrs w/o removing the cover and it never leaked yes it was full of fluid lol.

I use gaskets with a skim coat of rtv black. Never had a leak and the covers require some heavy wrestling to get back off. Just make sure both surfaces are absolutely clean of all oil/dirt and junk or you'll end up with leaks no matter what you do.

Got a gasket, now to swap it out. After a few hard hits in sand lake, my front diff is now empty. ;)

I found the cheap rtv seals better I think the expensive right stuff gets to hard. I switched to the cheap rtv and haven't had a leak since

I just use basic cheap black rtv....0 leaks on either cover even after repeated abuse. (Ruff stuff covers, hp 60 and sterling 10.25)

Been using the "right stuff" for years..no issues.
I pulled diff cover off, 5 lower bolts were bent bad enough that they barely wanted to thread out. Seems like the diff cover was shifted up.
So I think that's why it keeps breaking the permatext seal.
I bought a diff cover gasket for the front put all new bolts in.
Currently not leaking BUT I haven't smashed it into something yet.

If that ends up leaking, I'll try the Grey stuff cheapthrills suggested.

Thanks for all the suggestions I'll let you know if the gasket works.

What I've done in the past was to put whatever sealant... I use ultra black or ultra copper, in a nice bead all around the cover and bolt it on. Don't tighten the bolts up all the way. Let it sit over night or longer if possible then tighten bolts and fill with gear lube. The silicone cures in a thicker form and doesn't get squished out.

Maybe time to tie your diff cover in with your axle truss?

Go big or go home, right?

I have lube lockers and love them
Only time they have started to leak is when the bolts loosen up

I use these on both the front and rear D60's, never had a leak in 4 years. Pulled them probably 3 times to check and change oil and reuse with no issues.
