Putting a new carrier and gears in my dana. I'm trying to figure out how much CARRIER preload I need and there is very little info out there on it. I spread my case with the spreader .015, and simply could not get the new carrier in there with shim stacks from old carrier. (I made setup bearings as well) So, is it acceptable to make it a snug fit with the case spread .015 and when the spreader is removed will that provide enough? Thanks...
