⚠️ Safety & Precautions

• ⚠️ Work on level ground only, and support your Grand Cherokee with jack stands before going underneath or pulling hard on parts.
• ⚠️ Never let the brake caliper hang by the brake hose. Hang it with wire or a caliper hanger.
• ⚠️ The front hub bolts and axle nut can be very tight. Use steady force and keep the socket fully seated.
• ⚠️ If equipped with front wheel speed sensor wiring at the hub, disconnect it carefully so the ABS wiring is not stretched or twisted.
• ⚠️ Battery disconnect is not normally required for this repair.

📋 Before You Begin

• 🚗 Park your Grand Cherokee on flat, solid ground.
• 🅿️ Shift to Park and apply the parking brake.
• 🧱 Place wheel chocks behind the rear wheels.
• 🔩 Loosen the front lug nuts slightly before lifting the vehicle.
• 📌 A hub puller is a tool that pushes or pulls a stuck wheel hub out of the steering knuckle without damaging nearby parts.
• 📌 A torque wrench is a tool that tightens bolts to an exact tightness so parts do not come loose or get damaged.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Lug Nuts

• Use a 22mm socket and 1/2-inch drive breaker bar to loosen the front wheel lug nuts about 1/2 turn.
• Do not remove the lug nuts yet.
• Loosen before lifting the tire.

Step 2: Lift and Support the Front

• Use a floor jack to lift the front of your Grand Cherokee at the correct front lift point.
• Place jack stands under the proper front support points.
• Slowly lower the vehicle onto the jack stands.
• Gently shake the vehicle by hand to make sure it is stable.

Step 3: Remove the Front Wheel

• Use the 22mm socket to remove the loosened lug nuts.
• Remove the front wheel and place it flat under the frame area as an extra safety backup.

Step 4: Remove the Brake Caliper

• Use a 13mm socket or 15mm socket, depending on the caliper bolt head fitted, to remove the brake caliper slide bolts.
• Lift the caliper off the rotor.
• Use a caliper hanger hook to hang the caliper from the suspension spring or upper control arm.
• Do not pull, twist, or stretch the rubber brake hose.

Step 5: Remove the Caliper Bracket

• Use a 21mm socket and 1/2-inch drive breaker bar to remove the two caliper bracket bolts.
• Remove the caliper bracket and set it aside.
• When reinstalling later, tighten the caliper bracket bolts to Torque to 176 Nm (130 ft-lbs).

Step 6: Remove the Brake Rotor

• Pull the brake rotor straight off by hand.
• If it is stuck from rust, tap around the rotor hat with a rubber mallet.
• Do not hit the wheel studs directly.
• Rust can hold the rotor tightly.

Step 7: Disconnect the Wheel Speed Sensor Wiring

• Look behind the hub for the ABS wheel speed sensor wire, if your replacement hub includes a sensor lead.
• Use a flat-blade screwdriver to gently release the plastic wiring retainers.
• Use a 10mm socket if a small bracket bolt holds the wiring to the knuckle.
• Unplug the connector by pressing the lock tab and pulling the connector apart.
• Do not yank on the wires.

Step 8: Remove the Axle Nut

• Use a 36mm axle nut socket and 1/2-inch drive breaker bar to remove the front axle nut.
• If the axle nut has a locking stake or retainer, use needle-nose pliers or a flat-blade screwdriver to remove or release it first.
• Discard the old axle nut if a new nut is supplied.

Step 9: Free the Axle from the Hub

• Push the axle shaft inward through the hub splines by hand.
• If it is stuck, thread the old axle nut on a few turns and tap the nut with a hammer.
• Do not mushroom or damage the axle threads.
• Thread the nut on to protect threads.

Step 10: Remove the Hub Mounting Bolts

• From behind the steering knuckle, use an 18mm socket and 1/2-inch drive breaker bar to remove the three hub and bearing assembly bolts.
• Turn the steering wheel slightly if you need more room to reach each bolt.
• Keep the socket straight on the bolt head so it does not round off.

Step 11: Remove the Old Hub Assembly

• Pull the hub assembly straight out of the steering knuckle by hand.
• If it is stuck, install a hub puller kit (specialty) and remove the hub from the knuckle.
• You may also tap the hub flange evenly with a hammer, working side to side.
• Do not strike the steering knuckle hard enough to crack or deform it.

Step 12: Clean the Mounting Surface

• Use a wire brush to clean rust from the steering knuckle bore and hub mounting face.
• Spray the area with brake cleaner spray and wipe it clean.
• Apply a very thin film of anti-seize compound to the knuckle bore only.
• Do not get anti-seize on the brake rotor or wheel studs.

Step 13: Install the New Hub Assembly

• Slide the new front wheel hub and bearing assembly onto the axle splines and into the steering knuckle.
• Align the bolt holes by hand.
• Start all three hub bolts by hand first to prevent cross-threading.
• Use an 18mm socket and 1/2-inch drive torque wrench to tighten the hub bolts evenly.
• Tighten the hub bolts to Torque to 149 Nm (110 ft-lbs).

Step 14: Install the New Axle Nut

• Install the new front axle nut by hand first.
• Use the 36mm axle nut socket and 1/2-inch drive torque wrench to tighten the axle nut.
• Tighten the axle nut to Torque to 135 Nm (100 ft-lbs), then rotate an additional 90 degrees if using a torque-to-yield replacement nut supplied for this hub style.
• If your replacement nut uses a cotter pin or retainer, install it with needle-nose pliers.

Step 15: Reconnect the Wheel Speed Sensor Wiring

• Route the ABS wiring the same way it was before removal.
• Push the connector together until it clicks.
• Use a flat-blade screwdriver to seat the plastic retainers gently.
• Use a 10mm socket to reinstall any small wiring bracket bolts.
• Make sure the wire cannot rub the tire, rotor, or axle.

Step 16: Reinstall the Brake Rotor

• Slide the rotor back over the wheel studs by hand.
• If needed, use one lug nut by hand to hold the rotor flat while installing the brakes.

Step 17: Reinstall the Caliper Bracket

• Position the caliper bracket over the rotor.
• Start both bracket bolts by hand.
• Use a 21mm socket and 1/2-inch drive torque wrench to tighten the bracket bolts.
• Tighten the caliper bracket bolts to Torque to 176 Nm (130 ft-lbs).

Step 18: Reinstall the Brake Caliper

• Place the brake caliper back over the pads and rotor.
• Use a 13mm socket or 15mm socket to reinstall the caliper slide bolts.
• Tighten the caliper slide bolts to Torque to 35 Nm (26 ft-lbs).

Step 19: Reinstall the Wheel

• Install the wheel onto the studs.
• Thread all lug nuts by hand first.
• Use a 22mm socket to snug the lug nuts in a star pattern.

Step 20: Lower and Torque the Lug Nuts

• Use the floor jack to raise your Grand Cherokee slightly off the jack stands.
• Remove the jack stands.
• Lower the tire to the ground.
• Use a 22mm socket and 1/2-inch drive torque wrench to tighten the lug nuts in a star pattern.
• Tighten the lug nuts to Torque to 176 Nm (130 ft-lbs).

✅ After Repair

• ✅ Pump the brake pedal a few times before driving so the caliper seats normally.
• ✅ Start your Grand Cherokee and check that the ABS warning light goes out after a short drive.
• ✅ Test drive slowly at first. Listen for grinding, clicking, humming, or rubbing.
• ✅ Recheck lug nut torque after 25-50 miles.
• ✅ If the ABS, traction control, or stability control light stays on, scan for wheel speed sensor codes.
