How about the abnormal noise of the door seal?
The exclusion is whether the rubber ring or the door lock rings. I will be the newspaper cut into ten cm wide strips, piecewise vibration in the seal and the door on the contact surface, close the door after the running test, if the noise disappeared then that is sealing rubber friction noise, and noise elimination of rubber sealing. Basically, within 3 years of the car are sealed, abnormal sound.
Which door is the exclusion?. If the uncertainty is the front door or door rang rang, looking for a bumpy road, to ensure that the noise appears in the low case, to fasten the safety belt and the confirmation to the driving safety, the driver will test the door slowly opened, continue to run, if sound is proved to be the back door, let a friend sitting behind as is the method of experimental confirmation of the door.
Exclude door locks. Looking for insulating black tape, lock the door lock with black tape wrapped around a layer, tightly closed the door to drive, abnormal sound disappeared, it proved that the door lock hook and lock column friction produce abnormal sound, my car is this problem.
