One other thing that I have seen is on two piece driveshafts the slip yoke at the center bearing can hang up on the splines. Coming to a stop and depending on rate of decel the yoke can hang up on the splines then snap free/forward giving you what feels like a shift.
There was a TSB on that many years ago. It also affected the single piece rear shafts. The slip spline at the rear shaft on the transfer case could bind and release. My experience the shorter the wheel base the worse the condition. It never hurt anything but was a common concern by many customers.
