JEEP XJ REAR SPRING HANGER BRACKET

support the vehicle using jackstands to take the weight of the vehicle off the rear suspension. Leave the jack
under the rear axle for the duration of the installation process.
a. Remove the wheels, U-bolts, rear spring to shackle bolt, and forward spring to spring hanger bolt
and remove the leaf springs.
b. To prevent damage to the interior of the vehicle, lift up the carpet in the rear passenger footwell
as drilling into the vehicle will take place here. The bottom of the rear seat, and carpet
underneath it will also need to be removed to access some of the holes drilled and prevent
damage to the carpet.
2) With the rear springs removed, removal of the forward spring hanger can begin. Note that the forward
spring hanger is spot welded to the vehicle in many places. It is not necessary to remove every part of the
bracket and is not recommended since it is difficult to do without damaging the unibody around the hanger.
a. Start by cutting off the outer and forward portions of the spring hanger as shown in the following
