If you can just replace a washer the old plug should be fine. In my opinion only. When I did my front and rear differentials and transfer case I just reused my plugs (fill and drain) and didn’t even replace my washers. 20k miles ago and they are all perfectly dry. No seepage. No discoloration. No dampness. Again- that’s my experience with it.
Oh yeah. I have also done it the same way on my X drive BMW and my other rear wheel drive BMW.
Just always loosen the fill plug before the drain plug so you know you will be able to refill it.

 

Three Land Rovers over 20 years and ditto. To be honest I replaced nothing.

 

 

Grab a magnetic drain plug for your transfer case. $25 and some change, I run this one - very well made & strong magnet.
