DEX410 center driveline imbalance?

Guys, is this normal?

Have I done something wrong with the build?

It runs fine, just seems a bit excessive this imbalance. And a bit noisy.

I'm also thinking this could cause more wear.

(This is the original DEX410, with an Atomic-Carbon Ultra carbon chassis)
