Avoid jacking up the Jeep on:
* Axle tubes: These can bend easily under pressure.
* Differential: This is a crucial part of the drivetrain and shouldn't bear the weight of the vehicle.
* Control arms: These are suspension components and not designed for jacking.
* Body panels: These will bend or dent easily.
To be absolutely sure, consult your owner's manual. It will have diagrams and recommendations for the safest jacking points.
When jacking up any vehicle, always use jack stands for safety, *never* rely solely on a jack.
