diff plug?!

[indiemo]

So I climb under my TJ this morning to change the diff fluid because I notice it's been leaking and it's about time for a change. So I go to remove the filler plug and instead of a metal threaded plug, there's this piece of rubber similar to the drain plugs in the body, with the Dana insignia molded into it...and surprise, surprise, that's what seems to be leaking. Shouldn't this plug be a steel threaded plug??? I'm a bit confused and don't want to mess with it so I don't make the leak worse. any help would be appreciated.

Nope, rubber is the norm. To completely change the fluid, you need to pull the cover and re-seal it.

D35 has the rubber plug, while the D30 up front has the threaded steel plug. Who know's why, but that's the norm.

any idea where I'd go about getting a new plug being that this one is leaking?

If your plug is damaged, probably need to get a new one from a dealership. It should work fine as long as the hole and the area around it is clean before putting the plug back in.
