I have a F150 4x4 Screw 5.4 3.55 LS with 5,500 miles. Just within the last month I have noticed on occassion when taking off from a stop sign or light, the rears tire feel like they spin for a second or two then catch and off we go. If the pavement was wet, I would understand this, but this has been on dry surface.
I have been reading thru the threads and have seen the issues about back end vibration and the clutch packs, but the symptoms don't seem to match up.
It is going into the dealer on 12/14 to have them look at it. Any words of encouragement would help.
