Differential Help!

[cdymyd]

I just got a gasket for my differential but idk if that is the problem now that i jacked the car up and looked at it...
can somebody help me?

Looks like a bad half shaft seal.

 

[cdymyd]

does that have anything to do with the cover gasket?

 

[kustomizingkid]

I just use silicone between the cover and case, I don't even know if there is an actual gasket...

when i was under the car all the fluid was on the driver side axle of the diff and the passenger side was clean

Like Laser said.



Bad half-shaft seal.

Thats not that bad of a replacement on these cars. Also where did you get the gasket? When I changed the fluid in my 03 Cobras it just had the gray silicon on it and thats what I used to reseal it. I would just use silicon. Important thing is to let it cure for 24 hours before you refill the diff.

Good time for a Trac Loc

Yep, my Ford book tells me to use a bead of silicone. Didn't bother with a gasket either.

so what's better? Gasket or sealant?

 

[LaserSVT]

Silicone

6 in one hand, and a half-Dozen in the other.

I can see myself making an awful mess with the silicone sealant....

 

[LaserSVT]

The Mark has plenty of room to work back there unlike the Cobras so no problem with making a mess as you have room to work.
I would suggest getting the Ford gray silicone but the red or blue RTV should be fine as well. It is important to let it cure for 24 hours after re-assembly before you put fluid back in the diff.
