Either way - I'm meeting with TJSWJ in about 3 weeks for a new front axle. I'll just bolt new pads / rotors on and with a new everything I should hopefully be good.
Think about it like this. A warped rotor is essentially causing the pads to grab a certain part of the rotor harder than in another part, which is the pulsation you feel. I know from having a lot of experienced with warped rotors that it depends on where the rotors are positioned in their rotation as to what type of pulsation you experience. If both are "grabbing" at the same time, the steering wheel doesn't tend to shake much, but you can feel the front-to-back pulsation when coming to a stop. If one side is grabbing and the other is at its "non-grabbing place", then they switch due to the rotation of the wheels, then that is what causes the shimmy in the steering wheel. This back-and-forth "grabbing" gets the steering components moving ever so slightly and initiates DW. With warn components such as bushings, this little movement is exaggerated and the rhythmic properties of blah blah blah take over and that's what you feel in DW. Again, warped rotors are not the CAUSE of DW (that would be warn components) but can be what INITIATES it... That is why I said replacing your rotors will buy you some time as it will eliminate that small movement in the components. But this is only a band aid. You need to see what is warn out bushing wise and replace that to completely stop DW.
