I get banging when under 'hard' braking... it's usually the front of the car grounding out!!! But I'm looking to get the upper mount replaced soon... knocking sound when pulling away/clutch engaging (more so when cold!!)... I'm hoping it (along with the vibrations) is part of the mount weakening!! fingers crossed...Hi people. any one know what this could be? when i break hard or some times accelerate fast. I get bang noise or a thud from the font and have know idea what this could be. any ideas?
