Been to 3 different shops now for an opinion and received the same answer all 3 times...The sound is not normal, but wait until it's worse/more consistent so it can be pinpointed. One guy did mention some rust on the torsion bar keys, so he sprayed them, but to no avail. I guess I'm dealing with the popping until it gets worse. I can't figure out why it only does it when the wheels are turned and applying brakes. I'm stumped.
