Dana 44 fill plug sticks out, is this normal

[blazinear]

Is it normal for the fill plug to stick out this far? I just noticed this after a deep clean of my front diff. This plug was completely caked in grime before. Feels strange that so many threads would be showing when it's torqued own. I wonder if I have some aftermarket plug that's not right for the Dana 44. I know these also come in "innie" and "outie" varieties. I have the innie in my rear 9" and it seats perfectly.

More of an opinion…. But if it’s not leaking, don’t mess with it. You may create a bigger issue by “fixing” it.

I would say that it is about Par for the course... In other words, yes threads would be exposed. ^^^ agreed, if not leaking your fine.

Best guess is that you have a standard NPT plug, not an NPT flush type plug. The difference is that the NPT flush thread run a larger taper than the standard NPT threads. FWIW, standard NPT uses a 3/4" per foot taper, whereas a NPT flush type threads would use a 7/8" per foot taper, causing the plug to seat deeper into the mating part.

How many turns does it go in? 2 or more? Doesn't leak. It's fine. No real pressure on either side. If it bottoms, the threads won't seal.

They are designed in "NPT" style T stands for Taper. Meaning they slightly widen from inside to out hence they give you extra threads for a more flexible fit. Thats by design.
