The key here is "synthetic", not just the weight rating change. They most likely decided that the additional protection and temperature reduction provided by synthetic lubricants would help to reduce the occurence of rear diff failures.
I have been using and recommending Redline synthetc lubricants in vehicles for 20+ years, and have yet to see a lube-related failure in any component in all that time. I changed out my FJC soon after I bought it, and when you look at any component that has been run in sythetic oils for any length of time, you can see the difference.
You'll notice more and more OEMs are using synthetics in their transmissions, differentials, and even their engines. This is no accident - it is better for your vehicle.

does Napa, Advance, or Autozone have the redline products?
