At apx 10,00 miles on my 2010 f150 I started getting a clunk/bump in the driveline when stopping and starting. Sometimes it was worse when turning. I am a 20 year vetran mechanic with prior Ford dealer expierience. I have not been able to get this issue resolved by the local servicing Ford dealer vanbortel Ford. It has been in many many times for the same complaint. In the life of this vehicle it has had an engine replaced at 20,00 the torque convertor at 25,000 the driveshaft at apx 35,000 the rear springs at 37,000 and the issue still persist's. It is in now on 12/26/2012 for a trans leak, poor engine/trans performance and reduced ecomomy from reflashing the trans several times as well as the same clunk/bump when starting and stopping. My concern is that the unkown defect causing clunk/bump could cause a safety issue by locking up or failing at speed.
