hi, i have a trek marlin 5 and it has a creaking noise whenever i pedal hard and go off from a stop. ive gotten a new bottom bracket, greased the pedals, serviced the headset and greasing the rear derailleur hanger. could my frame be cracked? any help and tips will be appreciated. thanks!
ps. my cassette makes a slight sound when i backpedal, could my bearings need servicing? ive been cleaning and degreasing my cassette usually without removing it, just by spraying degreaser and scrubbing gunk off it.

This may be an optical illusion, but it looks like your whole frame is flexing
