Transfer case drain plug seized

Recommended Posts

New to me 2008 Tahoe.

140K miles

 

Completing fluid changes so that I know.

Fill plug first ... was tough, but it never required a lot of force to get it out.

 

Got about a full turn coming out and it began getting really difficult.

Tried to go back in and it was just too hard to move.

 

Doesn't appear to be cross-threaded.

 

I stopped before I cracked the case.

 

I'm open to suggestions going forward.

If it's not leaking, buy a small vacuum extractor and vac it out through the fill hole. Use never seize on the fill plug.

I had to use an ez-out screw extractor and some heat from my propane torch on my Jeep last year. They say that if you use the right bit you won't go through it. However, I did. I just flushed through some extra fluid to get most of the metal out. Then get a new plug and use anti-sieze on the threads.

Note: it started to turn then stopped...that indicates to me that the threads are galled, removing the plug will only continue to damage the threads.

That and the fact it wouldn't go back in.

Threads are definitely galled.

 

I'll use my suction gun and pull all the fluid I can out and call it good.

 

I don't think it's worth the effort to repair.

Just flush it as best I can, seal it and forget about it.
