So the other day I got replaced the pads on my jeep and when I jacked it up i put the jack under the lower control arm where the bushing is the bushing moved quite a bit.. So i lowered it and just jacked up the axle tube not thinking anything of it.

Now I have a terrible wobble when braking above 45 mph. It's only happened twice and both were going down hill around 45-50 mph. It was so bad i went into the other lane cause I couldn't steer or brake. It dosen't wobble on the freeway, I had it up to 75 and hit the brakes and its all good.

could this be from the lower control arm bushing being loose, or have people had problems with this with a slightly warped rotor?
