Okay so I was doing my rear drum brakes on my 2006 Toyota Camry LE. I cannot get the left drum off to do the brakes and I have tried my hardest! I need some advice to get it off and I have tried most internet advise!

Also got a stuck O2 sensor on my downstream exhaust that I can’t get off to replace it.

Lastly there is this weird noise coming from the back (maybe it’s cuz I did the shoes and didn’t put drum on right?) It sounds like the back is vibrating but it isn’t like screeching or anything like that. Any advice will be appreciated!
