I use 4K front and 6K rear.

isn't 4k or 6k too thin of silicone? i heard some people using 100 000 wt silicone and up....

I live in Arizona. We wet the track down, so I need my diff to slip more. Try what ever you feel is right and modify from there.

So what weight did you end up going with? How much did you add? Fill how? I just replaced my pinion and crown gears. I am guessing I add enough fluid to just touch the four diff side gears then bolt the crown gear to the other half.The fluid that was in there was very thick like molasses, and not much in there either.

I ended going with 7000cst weight oil, that's what was available at the time, i fill up almost to the top of the 4 spider gear...
