Hello jajalaya,
Welcome to Apple Support Communities!
We understand that your iPad Pro is making some weird vibration sound when you make a swipe up gesture. We're happy to help!
It would be best to have a technician take a look at your iPad. This can be done by going to a local Apple Store or Apple Authorized Service Provider.
You can find locations close to you by going to Apple - Find Locations. This will also give you contact information and allow you to make a reservation. You can also reach out to Apple directly by checking out this link to Contact Apple Support and they will be able to review your options as well. Also, check out this link for additional information about iPad Repair.
Let us know if you have any questions.
Thank you for using Apple Support Communities.
Take care!
