Important Notes:

All photographs show the left hand side installation, unless noted (Right hand side is similar). All steps must be repeated for the right hand side.

Perform a complete installation on one side at a time to keep the axle from shifting out of place during installation.

1) With the vehicle on level ground and at normal ride height, place a mark on each rear shock where the dust boot meets the body of the shock.

Raise Vehicle

1) Locate a level, stable and clean surface, suitable for supporting the vehicle on jack-stands.

2) Chock front wheels.

3) Refer to the Owner’s Manual to identify the correct location of the jack for raising the vehicle. Jack up the vehicle, and secure it on a pair of jack stands to the frame (not the rear axle), again referring to the Owner’s Manual for jack location points.

Warning: Never leave any vehicle supported by only a jack. Always use jack-stands. Serious injury and/or death may result.
