After changing the front diff went and installed two new rotors/pads in the back and turened front rotors and new pads. Still trying to figure out if I shouldve bought two new rotors for the front. I am suspicious that I had faulty rotors from day one. They were very groovy and rusty. The pads still had about 50% life left on them ... my assumption that stock pad can last to 60K miles (if rotor is not eating it). To replace tranny filter is a whole different story.... I think there is a need to remove pillar support from tranny in order to replace the filter.
