rear rotors are $150 each from dealer after market ones vary $80 $130 etc didn't get to ask about fronts are they all made in china or are ford rotors better?


do the rear bearings need to be greased or the gear oil takes care of that


front locking hubs how much grease should be on the out ring teeth if any?

 

You can get rotors much cheaper than $80, check out here:

No way would I pay $150 for a rotor from the dealer. The quality may be a little better, but certainly not worth more than twice as much. Your rear wheel bearings are lubricated by the gear oil in the axle.
