Rear wheel axle clicks and clanks. Help!

Your hubs/bearing are shot. I just did them on my 2011 with 130k miles on it, had the same noise before replacing them.
Do yourself a favor and buy quality parts (like SKF, same as OEM and made in Japan, I verified this with my old ones!). DO NOT USE CHEAP local auto chain brands, as you will need to replace them in 3 to 6 months again. FYI, the Timkens are just rebranded SKF for more money.

Never mind, I'll end up listing just about every part of a car thats not a piece of the interior................ brutal..
