Shock absorbers on your Cherokee grasp the SUV's target from bouncing also still as you operate down the course. Load-adjusting shock absorbers, such as those from Monroe, own you to lift and lower the vehicle to compensate for lighter and heavier loads. By increasing the air force in the shock absorbers, you Testament in essence lift the bound of the vehicle on which the shock absorbers are installed. By letting air impact gone, you Testament essentially lower the vehicle.
Instructions
1. Grounds the Jeep on a positive, flat surface. Dwelling revolve blocks in front and extreme one of the front wheels.
2. Lay the jack under the rear axle housing. Lift the Jeep until the rear wheels are clarion of the ground.
3. Settle the jack stands under both sides of the Cherokee, conscientious in front of the chapter spring on the frame. Lower the Jeep carefully onto the jack stands.
4. Slide under the Jeep. Loosen the top mounting bolts on the shock absorbers by turning the nuts counterclockwise with the ratchet and socket. This will usually be either an 11/16 or a 3/4-inch nut. Set this nut and washer aside.
5. Remove the lower mounting bolts by turning the nuts and bolts counterclockwise with the ratchet and socket and a wrench. These bolts and nuts will usually also be either 11/16 or 3/8 inch.
6. Pull the upper mounting eyelet off the frame bolt on both shocks. Pull the lower mount off the lower bolts. Set the old shocks aside.
7. Reverse the process of removing the shocks from the mounting locations. Reinstall the washers on the top mounts and thread the nuts onto the bolts by turning them clockwise by hand. If you have a Cherokee, tighten the upper bolts to 17 foot-pounds of torque. Slide the collet over the air line, followed by the O-ring. Thread the collets onto the "T" by turning them clockwise by hand. Using the wrench, tighten the collets to approximately 30 foot-pounds.13.
If you have a Grand Cherokee, tighten them to 68 foot-pounds. If you have a newer Grand Cherokee, the torque is 115 foot-pounds.
9. Find a suitable and safe mounting location under the rear of the vehicle to position the air T and valve. Drill a 3/8-inch hole and insert the valve through the opening. Place a washer over the valve and thread the nut onto the valve by turning it clockwise. Tighten this nut to approximately 20 foot-pounds.
10. Route the air lines from the valve to the shocks, avoiding pinch points and the exhaust pipes.
11. Slide the threaded collet over the end of the air line, then slide the rubber O-ring over the air line. Insert the air line into the shock absorber air inlet and thread the collet onto the air fitting by turning it clockwise by hand. Tighten the collet to approximately 30 foot-pounds with the wrench. Repeat this process on the other shock.
12. Move to the air valve and the "T" and trim the air lines to give one inch of slack in the air line. If you have a Grand Cherokee, tighten them to between 70 and 80 foot-pounds.8. Thread the nuts onto the lower mounting bolts and hand-tighten by turning them clockwise. If you have a Cherokee, torque these bolts to 46 foot-pounds.
Pressurize the air lines to 50 pounds per square inch. Spray all four fittings with the water and dish soap mixture and carefully watch for air bubbles. Tighten any bubbling fittings.
14. Raise the jack until the vehicle is off the jack stands. Remove the jack stands and lower the jack. Remove the jack from under the rear axle.
