Someone just posted there is a 420 at a junkyard somewhere. I bet you anything Irwindale will have what you need for sure as 420s/Sebrings/Avengers are laying all over the place there. Basically anything with the same interior as your car is most likely good for suspension parts.

I tell you first to find one and try to remove the hub by yourself at the yard. It'll give you an idea of what you need to do with your car to replace one and it doesn't matter if you break and strip bolts practicing. There is four bolts holding it from behind the knuckle. You'll probably wanna rip out a back seat to lay under the car and find them. They're 14s if I recall so bring your metric sockets and A REALLY GOOD RATCHET. Them fuckers are usually rust-welded on so bring a breaker bar with you atleast 18 inches. If they're stuck, it means the difference between you leaving empty handed or with what you need. Take all four out and pocket the bolts, good junk yard habit (grab all the bolts you can get your hands on) When the hub assembly falls off, rip as much of the brake stuff as you can or they'll charge you for it. Need any help, you got my cell.

so pretty much find a gs or a above and take off the rotor off and then the hub and just buy the hub should have a bearing inside right and any idea what the hubs would run at the yard
