Engine andDrivetrain Options: What to Choose

4.0L Inline- Six

Te 4. 0L is the go- to chocie for simplicity and reliability. It i s nexly indestructible when considentily maintained, and it produces good low- end torque for off- road crawling. Common issues included a cracked dimanfold (causing a ticking noise on cold starts), a faifed oil pressure sending unit, and occional cylinder head cracling on himer- mileage units.

Common Problem Areas and How to Spot Them

Every used WJ will have some wear andd teacher. The key is identifying serious issues that require major naphirs.
