I used valvoline synpower 75w-140 in my LSD when I did it, doesnt need modifier and havent had any problems with it yet, noticed better ingagement after changing fluid, haynes manual says 5/16's below fill hole if I remember correctly

 

Here is a link to the whole kit: http://cgi.ebay.com/ebaymotors/Diffe...item2c4ed0685d

I am sure that there are other ways of getting these parts but I wanted to have them all together when I pulled the cover as I should be getting it finished up in the A.M. I don't think it was a bad idea at all seeing the finished product.

 

ok sounds good, i just gotta figure out if i have LSD or not.

i actually thought about going all my fluids to synthetic too, didn't know if it was worth it with the price obviously being higher and a higher chance of things leaking

 

I dont know if they make gear oil in 75w-140 thats not synthetic everyone I found was synthetic and the valvoline was the cheapest, havent had a leak except for a little weeping around plug but it was doing that before, if you know the rear axle hasnt been changed just look at the bottom of the hood when you open it will say it there next to gear ratio.

 

damn i wish there was a quicker way. no the rear diff. has never been modified. all i know is my rear end is a 9.25. i'll keep looking around to see if i have a LSD or not. i wanted to knock this 10 min project out this morning.

 

wouldn't it be 80-90 that i put in the rear diff?

also, if i added the LSD additive and i didn't have a LSD, would it benefit or would it get jacked up?
