Weird sound from under my car

[xXII-ChAoS-IIXx]

So I was powering through a corner and the I hear a slight knock from my rear.
And then after, there is this sound of knocking that is consistent with my speed. First I though something was rubbing on my tire, but I don't think that's the case. I've looked under at a glance and it looks ok. Also, when I am just letting it roll back or forth I feel a slight tightening or hesitation when I'm rolling. I've looked around the interwebs and I think it may be the csb but I don't know for sure.
I've also tried making sure it's not my diff, and my friend say sing it's coming from the front and just resonates tward the back.

I don't know, I'm in need of some advice

And as an I related issue I feel my engine runs to cold. The gauge stays under the first mark. But not In the blue as normal engine running

your wheel bearing is on its way out. Temp needle should be at 12 o'clock when running normal. I suspect that you have an incorrect t-stat.

That's normal operating temp for me.is it bad to be driving around like that?

[dnguyen1963]

A lot of people in a warmer climate would put in a 70C t-stat. In colder climate, your engine will not be as efficient because it would take longer to warm up. It won't hurt anything but mpg. It is best to put in the correct t-stat though.

So you guys think it's probably the wheel bearing? One of my friends think it might be my diff. Which wouldn't be too bad because I planned on replacing the diff with a good 3.73 LSD

So, update here.

I was driving home from work, and took a turn very gingerly around 10mph, and before you know it... It was indeed my diff. Rounding that corner and my diff just completely locks up luckily I was just two blocks from my house and manage to drive it the rest of the way crawling. I appreciate the help though. Now I just need to find a clean LSD.

Check that you even have a thermostat in there. When I bought mine, PO had removed the thermostat which made the temp read like you are seeing.
