Parking Rollback - sloppy?
I'm not sure what to call this, so I'll describe:

1. My driveway has the very slightest incline.
2. When I pull in, I press the brake, then throw the Limited into Park
3. I shut down the vehicle, and step off the brake
4. The Jeep rolls-back a good 6 inches, or more
5. Happens 100% of the time
6. Feels like too much slop in the system

My 3 other (older) Jeeps do not show a similar trait to the same degree on the same driveway.

I'm guessing this is probably normal, but I do not like it. It's a bit annoying, and was disturbing as my wife stepped out of the Jeep last night as I stepped off the brake.

Is this normal or common? Is there a name for this "condition" in case I choose to discuss with my dealer?

I dunno but it sounds like it might be normal. I think there is quite a bit of play in the WK drivetrain, and you're using the transmission detent to hold the vehicle on the incline. Try using the parking brake...although I find there's a little bit of play there too if you apply it after stopping.. On my fairly steep driveway I use the parking brake to actually bring the Jeep to a stop. Then shift to park. No slop at all that way. And I like to imagine that it keeps the parking brake drum clean of rust and the drivetrain free of tension.

Re: Parking Rollback - sloppy?
The slop is not in the driveline, but the parking paw in the gearbox and what you are doing will only cause you grief. You should use the park brake, then put the transmission into park, as it is not designed to take the shock loading of a roll back into the parking paw. Remember this is a 5100lb truck and can easily snap the parking paw and end up with your truck through your neighbours living room.

I agree, parking brake is appropriate on steeper incline. My driveway has just the slightest of inclines - handbrake not really needed - but yes, would clearly address this issue.

I raised the question as I do not see a similar issue with my other Jeeps in the same driveway.

I'm sure it is normal. I do the same as Archer with my wife's new Overland, as we have an incline as well. I (or her) pull in then keep the foot on the brake while applying the e-brake, put it in N then take foot off of the brake to let the e-brake take up the slack before putting into park. Otherwise you get a nasty clunk when dropping into R from park due to the drivetrain holding the vehicle in place. We did the same with her Accord previously.
