rear wheel bearing

I have a 92 honda civic dx and my back wheel is making a loud roaring noise i just wanna know is it my tires or my wheel bearing an if it is my bearings how do u change them out.

its pretty easy to change it out, exspecially if you air tools. Just take the wheel off and grab a 32mm socket and get that bolt off and it just pulls out.

hope this helps,
Wes
