Hi all.
Recently cleaned all the "engine", i.e. chain, front and rear derr's, system and cassete.
I did dissasembled the front system, wanted to remove the biggest ring, but then realized that the middle one is mounted to the big one, so assembled everything back.

Now - when im putting pressure on left pedal there's a mad сreek coming from bb area. At first i thought it's the new pedals (WTB grease guard) and installed old ones, but it didn't helped. I double checked everything and it's all fine. There's no creek when putting pressure on right pedal only on the left one.

Oh yeah, i do not have that "crank extractor" tool, so i cant really check the bb well

Any hints?

The bike is stock GT avalanche 2.0 disc
