Hi guys I think my bearings (rear) are nearly finnished

Get a loud noise from the rear which gets louder the faster I go

Bearings?

What damage can be done from driving the car whiles the barings are broken? Ive drove almost 200 miles since I 1st started to hear it



If so.. is it easy to DIY replace them? I heard about needing a hydrolic press?

Any pointers received with thanks
