Well i'm going to change the lube in my diff's, and i was wondering what is the oil recommended to use and what's a good brand? also since i have the rr diff do i need to add the lsd stuff? thanks
I would change it to 100% Synthetic like Amsoil or Redline.
I use the Amsoil Severe Gear 75W90
Good for about 75,000 Miles.
50,000 if you ride it hard, lots of off road, dirt, and towing, beat the hell out of it.
100,000 if just normal mostly street use.
