was driving for about 10-15 minutes in my 89 civic when a loud bang or knocking sound started coming from under the car sounded like rear suspension, faster i went the faster and louder it got, wut the hell could it be?

 

I would just put the thing in the air, spin the wheel, and see what's making the noise. Could be a wheel bearing maybe, they do get noisy when they go.

 

but noisy enough so the bang over takes the volume of ur music?

 

ttt, anymore ideas?
