What weight gear fluid

[cms6362845442]

Just got my spartan locker. Hoping to install it myself next weekend if it's not to difficult. Wondering what weight gear fluid to use? Kinda want to quiet down any clicking and clunking I hear on the street. Thanks!

i'd ask the manufacturer what they recommend for gear oil (usually 80w90) but i don't think your gonna quite the noise down any. that's why locker's aren't a good choice for the street.
