Scissors jacks or hydraulic jacks are recommended for all Jeep vehicles. To change a tire, place the jack beneath the spring plate under the axle, near the wheel to be changed.
Make sure that you are on level ground, that the gear selector is in Reverse (manual transmission) or Park (automatic transmission), the parking brake is set, and the tire diagonally opposite the one to be changed is blocked so that it will not roll. Loosen the lug nuts before you jack the wheel to be changed completely off the ground.
A floor jack, when properly positioned, can be used to lift your Jeep. Position the jack under the sub-frame rail or frame rail lifting locations only. After raising the vehicle, properly support it with jackstands.
