The freehub bearings in my gdx370 got shot after around 80-100km. The ratchet side bearing is very coarse to turn and makes a lot of noise, the outside bearing is tiny bit better. The bearings in the hub is smooth. This gave me a stupid idea of replacing the bearings with NTN ones since i can get them under retail price.
After the bearing change will this cheap hub run better than the og DT one?

As for the sticking ratchets i placed the same white washer as in the shell into freehub body and it works. I tired only using that small red spacer(the one that comes with EXP ratchets) but it was still sticking. With that plastic washer on both sides it works normally.
