After installing my rear strut bar, I hear all these weird noises but they have nothing to do with the suspension. I didn't reinstall the seats or seat belt torsioners to test it out first and when I was backing up the car I could hear this slosh sound, like my gas tank sloshing. It sounds exactly like if you were to have a little swimming pool in the back and the water moves side to side. Also, you know how sometimes on a cold day when you back up you can hear the brakes on the rotor, I hear that too. Also, I can hear this faint electrical sound when I turn on the car. No CEL's just all these sounds that have nothing to do with the suspension. Someone please help!
