2001 new brakes front still shakes

[racerjim0]

The Mrs. car, a 2001 monte carlo ls, has severe front end shake when applying brakes all the way up through the steering wheel, it had a bad hub bearing on drivers side and I replaced it. Had rotors turned and new pads, no change(they were slotted/drill type I bought 1 year thinking heat was a problem, secound and last time they can be turned). Its gone through 3 sets of rotors in 65,000 miles, 2 sets of dogbones. I was hoping the bad hub bearing was causing the braking issue and warping the rotors over time
Before, the shakes would go away with a fresh brake setup but would start coming back after 10,000 miles or so I also replaced the front brake lines a year ago hoping that would help. What else would cause this wobble during braking. The car drives fine. I did take the engine/tranny out about 4 years ago to beacause of stripped spines on overdrive shaft, that was fun. I am wondering, as I type whether o'Riellys screwed up when turning my rotors, though I still think there is another reason for the warped rotors
