Important Notes:

Prior to beginning this or any installation read these instructions to familiarize yourself with the required steps and evaluate if you are experienced and capable to personally perform these modifications. A factory service manual should be used in conjunction with these installation instructions. 

Refer to the parts list to ensure that all necessary components and hardware has been included. If any parts are missing please contact your local TeraFlex dealer for assistance. 


FRONT REMOVAL

1. Refer to the factory service manual for lift locations. Raise and support the vehicle. Remove the tires and wheels for better access. 

2. With 16mm wrenches remove the upper nut, retainer and grommet from the top of the shock. On 2012 Wranglers, the battery box interferes with access to the upper shock. Simply break away a section of the thin plastic to gain access.


Remove the lower shock nut and bolt with an 18mm.


FRONT INSTALLATION

The new shocks are gas charged and will expand on their own. Install a retainer and grommet onto the shaft of the new shock. Install through the shock tower hole. Install the other grommet, retainer and nut. Tighten the nut until the grommets bulge slightly. 


Reinstall the bolt and nut, torque to 56 ft-lbs.


REAR REMOVAL

6. Support the vehicle so that it is safe to work beneath.

7. Apply penetrating oil. These are captured nuts and a broken bolt here is a real inconvenience. Remove the two upper bolts with a 16mm.


Remove the lower nut and bolt with an 18mm.


REAR INSTALLATION

Install the new shock into the upper frame rail. Torque to 37 ft-lbs.


Install the lower bolt and nut. Torque to 56 ft-lbs.
