07 Denali XL Leak and Noise

[puckhead]

Hey folks! Been gone a while, recently got an 07 Denali XL for the wife. It has been great until recently.

I noticed a light oil leak on the garage floor. Is this something I will be able to fix or will a mechanic have to replace gaskets? Not really tech savy if you couldn't tell lol.

Also, we have noticed a slight hum while driving. Don't know if it could be bearings or what?

Thanks guys!

Hopefully it isn't a big problem. But if you don't know what your doing, and are not mechanically savy, hire a shop. It could get spendy.

That's usually what I end up doing, unless I get info here that I can follow and fix myself.
