Why is my vibration making a crazy buzzing sound?

I replaced my charging port and speaker on my phone and before this my Taptic Engine was working perfectly. I put everything back and when I turned it on it made such a loud buzzing noise I thought I broke something. Turns out it was the Taptic Engine, I looked up how to fix this issue and everybody said to tighten the screws, so I did. This did not fix the issue, so I bought a new Taptic Engine and the same problem occurred, same buzzing noise. It’s been about 3 months and I just now saw that it could be the charging port at fault due to a short or something. I have the original charging port so I will be checking my other charging port to see if the vibration works on that one but I want to know if buying a new charging port will fix the issue. Any thoughts, ideas, suggestions?
