I changed out the front hubs on my truck a couple of months ago trying to track down a shaking problem. Its a no brainer... remove tire/wheel... remove the 2 bolts that hold the entire brake caliper on, remove caliper, then there are 3 bolts on the backside, remove and the hub comes out. As mentioned you could end up paying as little as $100 a side, or not. Depends on what your VIN calls for. The guys on ebay that are selling the hubs for $100 are doing something a bit strange though. In 2006 there was a hub recall, Chrycorp provided this part at a reduced rate to the dealers since in the circle of things, Chrycorp just has to repay them for it in the long run. Well this is the part number they are selling you, they wont tell you this unless you ask them because they dont want to let you know(or maybe even chrysler)that they are selling these parts to the public. I was only able to use one of these as the other side used the regular part# since it has an ABS sensor. That one was about twice as much.

 

Got everything figured out, thanks everyone for the quick responses!
