Torque Specs:
If you work on your Jeep any at all you need a torque wrench. Did you know that the number one cause of warped rotors is improperly tightened lug nuts? Every fastner on your Jeep has a torque spec, some of these are critical, some are not so critical. Note that a torque wrench is a calibrated tool, never use it as a breaker bar and never store it with it adjusted tight, always back it off to its lowest setting when storing it. Also note that some of these specs are in in-lbs and some are in ft-lbs, there is a huge difference between the two, pay close attention to this.
