No, you can remove the plug assembly w/o disturbing the rest of the box.Does the entire box have to be disassembled to just replace the adjuster plug seal? I don't see anything in the links relating to replacing that seal that doesn't require the box to be complately disassembled.
Keith, Good idea. Worth a try. It only started leaking after it sat over the winter in an unheated garage.When we re did the Lemans Sport it had sat for quite a few years and of course the seal leaked. I put some of that stuff in that is supposed to swell the seals. It worked for the 12K + miles that we put on the car. Although I don't generally have a lot of faith in stuff like this, it's worth a try.
Not too bad. A couple drips after running. It hasn't been driven much yet this Spring so maybe it will do as you say.How bad is it leaking Von, maybe after some use and warm weather, it'll swell back up and quit. JMHO.
