Wheel Bearing Replacement
here is a video of a rwd model;
Bearing is two piece; https://www.ebay.ca/itm/For-2008-201...2:pf:0&vxp=mtr
If its 4matic, then its a one piece bearing, it will be like changing a front bearing on any fwd car, just get the knuckle loose from the strut/balljoints and bring it to a shop to have them press the old bearing in and install a new one. Then you just have reinstall the knuckle yourself.

I would only recommend Timken /NTN or National for bearing brands. Mercedes sources them from Timken anyway so if the dealer wants a lot more then that one on ebay, they're ripping you off for a Timken bearing inside a Mercedes box.
