Hello I am hoping for some help on a problem that has recently occurred to my mustang. I have been noticing a loud rattling under my car when I am slowing down, or going in reverse. It seems like it is coming from the directly under my seats and like right where the transmission ends. I dont think its the tranny because it shifts fine and smooth and doesnt slip at all. I also turned the car off and rolled it down a hill in neutral forwards and backwards and the noise still happened. It seems to happen as soon as i let off the accelerator to come to a stop then it completely stops once i have stopped. Ive looked under the car twice and didnt really see anything that grabbed my attention. Although i did discover my driver side rear sway bar bracket broke off so it shakes a little but it could not be possibly causing the noise i am hearing now.
If anyone could help it would be greatly appreciated. Im in no sort financial state to take it to an auto mechanic so I have a DIY on my hands. If you have any questions or need any more information please let me know! Thanks!
