New truck driveline slack? Tow vehicle topic :)

I have a 2016 F250 4X4 gas, 11,000 miles. At work I back into a parking space that has a very very minor angle to it. Rear of truck is lower than front by a few inches at most. When I depart for the day and put the truck in drive there is a half second hesitation and then a minor thunk and then all is well. It does not do this when parked on perfectly level ground. The other day I was backing up to turn around and the truck was still slightly rolling backward when I put it in drive and BANG, big clunk as it appeared to take up slack. Vehicle is currently at the dealership to check this out and they say they cannot find any problem. Any ideas?

Thanks, Marty

Try setting the parking brake before putting the trans in park when on non-level ground. That should get rid of the thunk when putting it in gear (probably the park pawl disengaging under load). Also, some driveline slack in any RWD drivetrain layout is normal, so there will likely always be a little bit of a thunk between reverse and drive.

Thanks. If I didn't always park my previous truck in the same spot for years and never had this happen I probably would have not even noticed. Just stood out to me because its a new vehicle.

I have noticed many of our new vehicles (mostly Fords) seem to do something like this. I figured it was the new design of the transmissions. It certainly isn't comforting to hear or feel.

willing to bet it is something to do with NVH. There is probably something on the shaft to dampen out vibrations... like the rubber donut found on BMWs and the like. It is allowing the shaft to "float" when not under a torque load
