So basically the vibration/knocking I feel in the firewall feels the hardest when I accelerate at lower rpms. I heard some new noises coming fron the front right too, dosent drive any different though. I havent had time to really look at it but im kind of puzzled... It all started shortly after I retightened my front right axle which was a bit loose and made my tires vibrate at highway speeds. I plan on taking the whole taking out to look at the axle but I dont have time to do that until the weekend.. could it possibly be caused by the axle?
