I got the fronts off without any problems.
The rear ones are a little more difficult. I just removed the coil pack and got to the back ones. There is no need to jack the rear of the engine up as some suggest, just move the coil pack and you should be able to access the rear ones. I used a mirror to help see the rear spark plug holes once i removed the old spark plugs. Make sure you label which wires go where prior to removal of old one. Factory wires come labeled 1 thru 6. I took a Sharpie marker and labeled the front and rear.
This is my first ever spark plug change. I am a total novice at auto repair.
Hope this helped you out.
Both V6 engines have 6 spark plugs
How to change the spark plugs
It is moderately easy to change the spark plugs on a Liberty, although it is rather tricky because of the gap between the spark plugs.

Spark plugs and wires
Changing spark plugs is relatively easy. Disconnect the batter and spark plug cables, and remove the old spark plugs. Next replace the spark plugs with new ones, reconnect the spark plug cables and battery.

Disconnect the battery, remove the spark plug cables and boot, and remove the old spark plugs. Put in the new spark plugs, attach the cables and boots, and connect the battery.
