Fix It

Sit in the drivers seat of your Jeep and set the parking brake. Insert the ignition key into the ignition and turn the key just far enough to unlock the transmission. Depress the brake pedal and shift the transmission all the way to the rear then turn the key back to lock.

Lift the rubber mat out of the front bin in the console, exposing the retaining screws under it. Remove the screws with a Phillips screwdriver and set them aside.

Open the armrest on the console and locate the two screws in the base of the compartment. Remove the two screws with a Phillips screwdriver and set them aside. Slide the rear cup holders out to allow you to access the two screws under the rear of the console.

Remove the rear retaining screws with a Phillips screwdriver. Lift the console up and over the shifters then set it aside.

Locate the two cables coming to the front of the transmission and transfer case shifts and pry the retaining clips up and off the bracket with a small pry bar. Using a screwdriver, pop the shift cable off the side of the shifter on both sides then lay the cables aside.

Remove the four retaining bolts that secure the shifters and bracket to the floor of the Jeep with a socket and ratchet. Lift the entire assembly straight off the mounting studs and remove it from the Jeep.

Lift the front of the Cherokee with a jack until it sits high enough to fit jack stands underneath it for support. Place the jack stands under the frame rails just behind the front wheels. Lower the Cherokee so that it rests securely on the jack stands.

Disconnect the electrical connection from the oxygen sensor. Remove the sensor with a wrench or oxygen sensor socket attached to a ratchet.

Spread a thin layer of anti-seize compound on the threads of the new sensor. Do not get anti-seize compound on the sensor head. Thread it into place by hand. Tighten the sensor with a wrench or a socket and ratchet.

Connect the wiring harness connection by pressing it together until it clicks. Lift the truck with the jack until you can remove the jack stands. Return the truck to the ground.

Open the drivers door of your Jeep and locate the access panel for the fuse box on the end of the dash. Remove the fuse box access panel by unsnapping it from the right cowl side trim panel.

Remove the nut securing the right cowl side trim to the junction block stud with a socket and ratchet. The nut is near the center of the fuse block.

Remove the two screws along the edge of the right cowl side trim to the right of the fuse box using a Phillips screwdriver. Set the screws aside.

Pull the trim panel off and locate the flasher inside the junction block. Unplug the combination flasher from the junction block.

Push the new flasher into the block. Position the trim panel back in place. Install the retaining screws along the right side of the fuse box and tighten them with a screwdriver.

Install the nut in the center of the fuse block. Tighten it with a socket and ratchet. Snap the access cover onto the fuse panel. Close the door of the Jeep.

Open the glove box until the stops on the back edge are resting against the rubber stop bumpers in the upper glove box opening. Reach into the glove box and, with the middle finger of each hand, push the rubber flap on the two glove box stop bumpers toward the front of the vehicle.

Roll the glove box door down until the stops on the back edge of the glove box pass through the openings in the upper glove box opening. Grasp both ends of the glove box door, then twist and pull the door as necessary to disengage the inboard hinge hook from the inboard hinge pin on the dashboard.

Raise the glove box door until it is perpendicular to the instrument panel then twist the door slightly counterclockwise and shake the door slightly to disengage the remaining two hinge hooks from the instrument panel.

Pull the glove box straight out of the dashboard. Set it aside in a safe place so you can reinstall it later if you will be reusing it.

Raise the Jeep off the ground using a jack and support the Jeep on all four corners with a set of jack stands. Be sure you are working on level, solid ground, before raising the Jeep, to prevent the jack stands or the Jeep from moving while you are working under it.

Locate the rubber hanger that supports the tail pipe behind the rear axle. Push the pin on the tail pipe out of the hanger and let the tail pipe hang down.

Move up to the muffler and locate the joint between the catalytic converter and the muffler. It will have an exhaust clamp holding the two pipes together.

Loosen the bolt on the exhaust clamp with a wrench or socket and ratchet and slide the two pipes apart. They may not come apart easily, so wiggle or turn the muffler to help free the pipe.

Slide the exhaust pipe and muffler out from under the Jeep as a unit and discard. Position the new exhaust system into place under the Jeep and lift it up, sliding the tail pipe over the top of the rear axle.

Slide the new muffler onto the pipe at the back of the catalytic converter, making sure it is completely on the pipe. If you do not get it all the way into place, the rear hanger will not line up.

Lift the tail pipe up and slide the pin on the tail pipe into the rubber exhaust hanger. Move forward and install a new exhaust clamp on the pipe that connects the catalytic converter to the muffler.

Tighten the nuts on the clamp with a wrench or socket and ratchet. Remove the jack stands from under the Jeep and lower the Jeep to the ground with your jack.

Locate the hub nut and cotter pin in the center of the front wheel on the side on which you will be working. Remove the cotter pin from the shaft with a pair of needle-nose pliers, then discard it. Place a large socket (generally 36 to 45 mm) on the axle nut, and use a breaker bar to rotate the nut counterclockwise until it loosens.

Loosen the lug nuts with a lug wrench, then place a jack under the front of the Jeep. Raise it off the ground, and place a set of jack stands under the front axle to support the Jeep. Remove the wheels, and set them aside for now.

Locate the two brake caliper retaining bolts on the top of the brake caliper. Remove the two retaining pins with a socket, then ratchet the lift the caliper off the brake rotor. Support the caliper from the top of the suspension with twine to keep it from hanging on the brake hose.

Slide the brake rotor off the hub, and set it aside. Locate the three 12-point bolts on the backside of the steering knuckle that retain the hub to the steering knuckle. Remove all three bolts with a 12-point socket and a ratchet. Set the bolts aside.

Remove the axle nut from the axle shaft, and pull the hub out of the steering knuckle and off the axle. If it has rusted to the steering knuckle, use a cold chisel and hammer to work around the edge of the hub, separating it a little at a time. It will come out with enough persistence.

Clean the interior surface of the steering knuckle with some break clearer and a clean rag then coat it with some anti seize compound. Slide a new hub over the axle shaft and into the steering knuckle. Install the three 12-point retaining bolts from the back of the knuckle and into the hub. Tighten the bolts, drawing the hub completely into the knuckle.

Slide the rotor onto the new hub and wheel studs, then position the brake caliper on the rotor. Install the retaining pins into the caliper, and tighten them with a socket and ratchet.

Install the axle unit onto the axle shaft, and tighten it until snug. Torque the three 12-point bolts to 75 foot-lbs. with a torque wrench. Install the tire on the hub, and tighten the lug nuts until snug.

Raise the front of the Jeep off the jack stands, then remove the stands from under the axle. Lower the jack, setting the Jeep on the ground, and tighten the lug nuts the rest of the way with a lug wrench.

Tighten the axle nut to 175 foot-lbs. with a torque wrench, and install a new cotter pin in the end of the axle shaft, bending the legs over with a pair of pliers to hold it in place.
