loud grinding noise when driving, lifted it up with jack, can move the wheel back and forth, feels like I could almost pull it right off!!

 

You have a lot of issues if you can almost pull your wheel off. You probably have a ton of different problems that can cause that. Wheel bearing, control arm, tie rods, rust, etc.

 

You need to be more specific. Is it moving in and out side to side...be more specific if youre looking for assistance unless youre just sharing a short story

Could be wheel bearing issue or potential ball joint or tie rod issue. Or just other misc bushings are shot.

 

Raise the car safely and then locate the source of the movement. Whatever is loose is what you need to replace - probably a wheel bearing.
