i got my brakes replaced about 1 months ago and shortly after that whenever i come to a stop and take off or speed up from a turn i would feel and hear a popping noise from my rear...at first i thought it might be my brake callibers locking up after being changed and took them back and had them rechecked and it was a negative on that....then i thought it might be my u-joints, but again wrong(even though i went ahead and changed them), i have replaced my rear control arms(upper and lower) and made sure the bolts were still tight.....and even the shockes....still making the sound...a friend suggested that when i changed the upper control arm i should of replaced the bushings also, but when i looked under the car they still looked ok....any other suggestions or should i replace the bushings anyway???
