Rotor keeps warping unevenly

[Regs]

About 2-3 years ago I hit a curb and it's never been the same.

First time I took it to the dealership I had to get a new tire/rim, hub bearing, and control arm replaced. Then I noticed my car was pulling hard to the right a few months later. So the second time I went back to the dealership they had to replace the control arms again (under warrentee) and replace the rotor.

Now a year later, my right front rotor (same one I hit the crub with) is worn unevenly again though at least my car isn't pulling right or left. What could it be? Break piston? Break calibers? The rotor itself?

warped brake rotors don't make the car pull, they cause pulsation in the brake pedal (or entire car, if it's bad enough).

is the pull when braking or all the time? if it's when braking, the most common problems would be a stuck caliper slide (or stuck caliper piston) or bad brake hose.

Sticking/dragging caliper (this will warp a rotor and cause a pull)

Sticking or dragging wheel bearing (this will warp a rotor and cause a pull)

umm...if it warped evenly that would be called "normal wear". 😉

If you hit something hard enough to bend the control arm, it's possible the knuckle was bent too, meaning the caliper is misaligned with the spindle. A small bend like that would go unnoticed and could be compensated for in the alignment, while leaving the caliper misaligned. Check that your pads are worn down evenly and not wedge shaped.

Though something like that would have symptoms leading up to the warped rotor, like pulling to one side when you apply the brakes.

Always double check lug nut torque as well when someone has messed with the wheel.

Especially if they put the wheel back on quickly with an impact wrench. :|
