Don't really know a lot about it but can these wheel bearings be repacked or is it sealed. My wheels don't spin all that great and makes a roaring noise. If it is sealed can it possibly be drilled n put a fitting in it?

 

Sounds like the rotors might need addressing.

 

The front hubs are not serviceable and are replaced as a unit (which includes the ABS sensor). The good news is that it makes it easy to do. The bad news is they are not cheap.
