i know ill get flamed for this but i honestly dont know.

Ive got my waggy 44's together and i have a full detroit in the rear and a tru trac in the front.....

do i need any addatives and what weight oil should i run for the break in and after that?

thanks i would ask JU but they dont know what lockers are over there. hehehe j/k

Stick with 80-90W

no additives, and make sure to get the synthetic gear oil. what's the name of that stuff in the blue bottle???

Here's what my gear guy told me after regearing my 44s:

75w90 standard for break-in (first 500 miles for rear end, first *whatever* for the front end, depending on how much action it sees--This could be the same as the rear in a front-end-always-turning vehicle like a stock TJ or far less in vehicle with lockouts)

75w90 synthetic from then on.

80-90W non-synthetic and change it more often. (ahh the sweet smell of contradiction) <IMG SRC="smilies/thefinger.gif" border="0"> <IMG SRC="smilies/biggrin.gif" border="0">
