New "shift" when stopping

[Tdubalicious]

Hey all! Something started happening today that hasn't happened before. When i stop at a stop light (right when you completely stop and your vehicle moves back a little bit) it feels like there is a shift coming from the rear end or the transmission area. And when I go to move forward, it feels like it does the same thing. It's hard to explain. It's almost like as soon as it stops and as soon as it starts, there is a little shift. You can deff. feel it, but is this something I should be concered about? If so, where do I even start??

Might be slop in the slip joint in the driveline. Ford made it sorta non servicable. It's a common problem. The bellows boot covering the slip joint needs to be removed so the joint can be pulled apart and greased.

Yep, grease your slip joint. My 05 did the same thing. Mark your drive shaft (timing marks) on both ends, remove band on rubber boot and apply grease to female side. (just smear it in there, reinstall boot and drive shaft. I had no way of putting new pinch clamps back on the boot so I didn't. Did that a year ago, rubber boot still there ( No Clamps) and no slippage. My 08 GMC had the same problem, took it to the dealer to get fixed (Warranty Work) and greasing the slip joint was their solution.

I wonder if it would be a bad idea or not worth it to drill a hole and add a zerk fitting in there
