Jimm 8/3/2014Difficult to say exactly what specific parts need replacing without a thorough inspection. How do you know the brake rotors and pads need replacing?
Raise the front end and support on jack stands, then remove the front wheels to perform a complete inspection of the brakes and fron hub bearing assembly.
The parts are readily available from these many on-line sources, www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities.
In fact, they (RockAuto) list the front hub bearing from around $65.00 each for your vehicle. Be sure to replace both sides (left and right) at the same time due to mileage / age / wear considerations. Keep in mind, these are only the parts prices - the labor to install will be additional cost. Check the 'How-To-Guides' feature on the Auto MD website for the specific steps to install.
