Or seriously warped brake discs, or knackered track-rod ends or steering swivels.
warped brake discs.
LOL - No, the brake discs are fine and if they were warped I would imagine distress at almost any speed. I guess track-rod ends or steering swivels are a possibility though unusual for a car that has done less than 30,000 miles and the nearest it has been off roading is the car park at Tescos. But thanks anyway, Mr King....

Another good reason not to buy converted American trucks!
Cant believe they werent obtainable in this country, the number of jeeps about with em on..
Amercian cars are generally easy to find parts for.
Absolutely - but fortunately I lease it! I'll take another look at the discs over the weekend - rather them than steering problems.

PS: Aren't Cherokees manufactured in Europe?
Even worse Austrian-Chinese American trucks from a German company
Assembled in Austia from Chinese and US bits.
Rear final drive failure tends to be quite common problem on them.

I'm not familiar with the specifics of the Grand Cherokee, but I've just tracked down a similar problem on my Range Rover. Over the space of 9 months I replaced the drag link and steering damper, adjusted the power steering centering and pre-load, swapped the tyres round, tightened the wheel nuts that were loosened by the vibration, and eventually had a new front diff fitted. The front diff is an unlikely cause, but wear and tear in the propshaft is common on rangies.
Having said all of that, if it's braking that causes the vibration, hen the first suspicion is warping of the brake discs.
You might want to try asking this question on uk.rec.cars.4x4 where someone more familiar with the Cherokee might well be lurking.
