when you open the gearbox stick the gear diff in one half of the gearbox (with the rest of the gears installed) without any shims and you'll notice it is level with the rest of the gears, adding the shims with only cause this tight friction people are getting.
It's true that no shims should be used. But the problem with friction is because of the gear being to big. Durango is looking at the problem.
