If you run thinner fluid in the center diff you will really have front tire issues if they are not properly taped. I ended up with a mixture of 75k and 100k fluid in the center diff in my muggy, running a neu 1521 1y with 6s. With 50k in the center diff it just unloaded all of thepower to the front wheels and they just spun and ballooned.

After adding thicker fluid and properly taping and balancing the tires all was good. I could get a 3/4 wheely and the truck would still turn well.
