10.5 Sterling LSD

[IDIoit]

Pretty sure I know the answer.
But I'm still drunk from lastnight.

Just finished the install of my LSD.

Do I need the friction modifier to go along with the 75/145 synthetic?

Yes. Unless you are using something like Royal Purple.

Don't add the full amount of modifier. Add half and do a couple of figure eights in a parking lot. If it chatter add more. Doesn't chatter its good to go.
Adding the full amount makes the LSD kind of useless.

i dont drift my truck lol
but slow figgure 8's sound like a good plan.
i used 3 quarts of diff fluid, may need another quart,

 

[trackspeeder]

Mellow figure eights are what you want to do. Although drifting would be more fun.

bad for my axles with 12.5 x 35's lol

The 10.5 is a 3 spider diff with limited slip? Will this fit in a 10.25?

I ask because a 10.25" I horse traded for supposedly has this. When it dries out I'll pull the cover off.
