It started about a week ago.... When your going down the road at around 25-30 it begins this thumping noise and the faster you go over 30 it gets a more rapid thump. but when u jerk the wheel the noise seems to go away then when ur going striaght again it begins the thump again??? alignment seems great... im leaning towards the breaks and rotors sound about right or no? sometimes when its thumping the break pedal may pulse. Im kinda lost
