My Auto Redline has done around 12k and overall its been great with a few issues already resolved by the dealer. Over the last few weeks I have noticed a thud sound coming from the driveline (not a metallic sound), possibility diff area. I can recreate it on any left turn slip lane where you slow down to check for oncoming traffic and as you accelerate out of the turn the thud sound occurs even under light acceleration. Any one experience this with VE/VF models? is this normal or cause for concern?
