Recently I have been getting this weird noise. When ever I get on it hard I hear a noise that sounds like the floor boards are crunching or something. But I see no signs of damage anywhere. Could it be the rear tires rubbing? broken torque boxes? rear end bouncing off the pinion snubber??? Anyone else ever had this problem? It's driving me nuts, I'm afraid to hammer it cause I get that loud thunking noise. Keep in mind I do run slicks at the track. I know it's not anything in the rear cause it's all new. Thanks
