Another Driveshaft Question

[jap7t8]

Long story short, I am replacing a driveshaft on my 90 sj. I am trying to re-use my existing skat trak prop that is still in really good shape. The first thread is screwed up on the prop so I want to buy a tap to clean it up. It will be a 20mm diameter tap, but what is the thread count that I need? Also, what kind of grease should I use to pack the bearings before I press the shaft back into the housing? And is there anything else I should do/replace while I have it apart?

Thanks!

I'm going to run either Moble 1 grease if I have enough or royal burble grease, I have been wanting to switch over to that in my jeep front end.

So does anyone know what the thread pitch is on a SJ prop? I know it's 20mm diamater and left-handed. I tried calling and emailing Skat Trak and haven't gotten a response. I really don't want to spend another weekend on dry land...

I found it. The thread pitch on a SJ prop is 1.5mm. So the tap size is 20mm x 1.5mm. Just figured I'd post it in case someone else is looking for it down the road.
