Have a 2012 FX2 and lately I have noticed when I am at a stop and then start to go I feel a little thump similar to a hard shift. it doesn't happen shifting from 1st to 2nd so on it only happens when I start from a dead stop. Anyone else experience a similar issue?

 

 

Thank you Tothemax, brought the truck to the dealership since it was still under warranty and it was the driveshaft, running smooth now.

 

Good deal
