So I just picked up a 2004 WJ Overland with a 4.7L.
I have had plenty of 4.0s and command track jeeps
but this has quadra-drive and the 4.7 H.O. that I don't know what to keep an eye out for weaknesses. I doubt this will see much more than dirt roads or gravel and chicago's glorious weather for offroading because it's the wife's but any heads up to keep an eye out for would be greatly appreciated.

Thanks in advance for any of your advice.
