Trouble Finding Rear Wheel Hub Replacement Info.

So, when I was getting my studs switched over, they told me my rear wheel bearing is bad. They wanted almost $400 to change it. But the rear wheel hub is held in by 4 nuts. So, no reason I can't just change it myself. I already ordered the new hub. So it should be here in a week or so. Meanwhile, I'm trying to study up on changing this out so I'll know what to do when something goes wrong or know what to expect. So, I've searched YouTube and Google and I'm not finding much of anything. I'm pretty sure my rear suspension is torsion bar and I have rear drum brakes. I did read something that the rear coil springs would have to be removed in order to access the nuts. Since mine has torsion bars, I shouldn't have to worry about that. Also my goal is to change out the hub without having to remove the rear brake shoes. I'll remove them if I have to. But if I don't have to, I won't. I have a basic understanding what I need to do, but the info out there is very lacking. It's like nobody has really done this repair. So, I've done my Google searches and what-not. So, I'm creating this thread as a last resort in hopes somebody might know where the info is. Thanks.

4 or 5 bolt hub? Year of your Cobalt would also help!

Well, I thought it had rear torsion bars because that's what was advertised when I bought it. Used my phone to shoot video from behind the tire and saw coil springs. Still not sure if I have to remove the coil spring to access the hub nuts, but it looks fairly easy. I'll try to get all this on video when I tackle this.

It has a rear torsion beam. That describes the rear "axle".

Shouldn't be too tough to do the hub, though.

What do I torque the nuts to the hub to? I'm not finding any info online.

Edit: I found somewhere that it's 33 ft/lbs plus 30 degrees. Anyway, it's back together now.

My drive to work this morning went well. Nothing came apart on me. When I was changing out the hub, I did have to remove the spring to get to the nuts and discovered it was broken at the bottom. I heard this was common with Cobalts. At least I know how to change them now.
