rumble

[lazzag]

On my 52 M3 SMG when ever I turn a tight corner (roundabout/junction) I keep getting a bad rummble from either back wheel , my local ( trust worthy) says there is no play on the drive but there is about a 30deg movement on the prop.The car drives fine on the straight and around ordnary bends but there is a bit of a thump when I change up when the pedal is down a fair bit.
Any ideas please

Get them to check for play in the diff could also be diff bearings or cv joints on your drive shafts
