How does one go about removing and replacing the front wheel bearings on the 2008 Kia Optima?

Unfortunately, I looked up your vehicle and it appears that you have pressed bearings, meaning you can’t undo couple bolts and put a new one, you have to have a press and a couple other tools. Your best bet is to take it to a shop, it’ll pay off just not having to do it yourself it’s a pain. Unless you like working on cars then look up “how to replace pressed-in bearings” Goodluck!
