Did you make tight figure 8īs after changing the fluids? In that way the fresh fluid (and additive) will be mixed well inside the diff locks. If it still seems to be binding in tight turns, then maybe some more limited slip additive is needed.
I changed the fluid in both diff's and the transfer case with the correct fluids and additive right after buying the truck in December. Doing so did not help the shudder at all. I even added another 1/2 bottle of diff. additive to the front diff. to no avail.
As for figure 8's, I did that when I first changed the fluid and have been driving the truck for over 2 months, it's definitely mixed in there well.
