hi guys. new guy here and i just picked up a ’10 rancher 4×4 foot shift. i am doing the full tune up/fluid changes on it so i have a baseline to start from. i ordered up three pints of the honda 80-90 hypoid axle lube and was wondering if there is a limited slip additive that needs to be added to this lube or if it is already in it. did a couple of searches but could not really find any info one way or the other.thanks!
