Need help

A rule of thumb is "vibrations" are caused by rotating parts, so it could be the wheel was knocked off balance, or you damaged the wheel bearing/hub, but hub damage would likely involve a lot more noise than you're reporting. You might have just knocked off a counter-weight from the rim. Of course you might have other minor damage too, sway links tend to take a lot of abuse and they do squeak or groan when going bad, as do tie rod ends. Best thing to do though is inspect it thoroughly or take it somewhere for servicing, as this is obviously a safety issue.
