🔧 Grand Cherokee WK - Wheel Bearing Replacement

On your Grand Cherokee WK, each wheel uses a sealed wheel bearing and hub assembly. When a bearing goes bad, you replace the whole hub unit, not just the bearing inside. I’ll walk you through the job step-by-step so you can safely swap it out at home.

Difficulty Level: Intermediate | Estimated Time: 1.5–2.5 hours per wheel

⚠️ Safety & Precautions

• ⚠️ Always support the vehicle with jack stands; never work under a car held only by a jack.
• ⚠️ You’ll remove the wheel and brake parts; keep the brake caliper supported with a hook or wire so it doesn’t hang by the hose.
• ⚠️ This job involves a large axle nut; make sure the vehicle is in PARK and the opposite wheels are chocked so it can’t move.
• ⚠️ Wheel speed (ABS) sensors and their wiring run near the hub; avoid pulling or twisting these wires.
• ⚠️ If you’re working outdoors, make sure you’re on solid, level ground so the jack and stands are stable.
• ⚠️ Battery disconnection is not required, but switch the ignition off and keep the key away from the vehicle so systems stay asleep.

📋 Before You Begin

• Park the Grand Cherokee on level, solid ground, shift to PARK, and set the parking brake.
• Place wheel chocks at the wheels that will stay on the ground.
• Loosen (but do not remove) the lug nuts on the wheel you’re working on with the 21mm socket while the vehicle is still on the ground.
• Lightly spray penetrating oil on the axle nut and the area where the hub meets the steering knuckle (front) or rear knuckle.
• Have a clean area ready to set removed brake parts where they won’t get dirty.

🔨 Step-by-Step Instructions

Follow these steps in order:

I’ll describe the front wheel hub first. Rears are very similar.

Step 1: Lift and support the vehicle

• Use the floor jack (3-ton) at the front center jacking point or appropriate pinch weld to lift the front of the Grand Cherokee.
• Place jack stands under the front frame or pinch welds on both sides and slowly lower the vehicle onto them.
• Remove the wheel lug nuts completely with a 21mm socket and 1/2" ratchet and pull the wheel off.

Step 2: Remove the brake caliper and bracket

• Turn the steering so you have good access to the caliper bolts.
• Use an 18mm socket and 1/2" ratchet to remove the two caliper bracket bolts at the back of the brake caliper assembly.
• Carefully slide the whole caliper and bracket off the rotor. If stuck, gently pry with a flathead screwdriver.
• Hang the caliper and bracket from the suspension spring using a brake caliper hanger hook so it does not hang by the hose.
• Do not press brake pedal with caliper removed.

Step 3: Remove the brake rotor

• Remove the small rotor retaining screw (if equipped) using a T30 Torx bit socket and 3/8" ratchet.
• Slide the rotor off the hub. If it’s rusted on, tap around the hat area with a rubber mallet until it loosens.
• Set the rotor aside on a clean surface.

Step 4: Disconnect the wheel speed (ABS) sensor connector from the hub

• Follow the wire from the back of the hub to its connector on the knuckle or nearby bracket.
• Use needle-nose pliers or fingers to release any plastic clips holding the wire to the knuckle.
• Press the locking tab and unplug the connector by hand; do not pull on the wire.
• Note routing so you can copy it on reassembly.

Step 5: Remove the axle nut

• Have a helper press and hold the brake pedal firmly, or insert a strong screwdriver between rotor vanes and rest it against the caliper bracket mount to keep the hub from turning.
• Use a 36mm axle nut socket and breaker bar to loosen and remove the axle nut.
• If the axle stub is rusted into the hub, thread the old nut back on a few turns to protect the threads and tap the axle inward with a hammer until it moves freely through the hub.

Step 6: Remove the hub mounting bolts

• From the back side of the steering knuckle, locate the three hub mounting bolts.
• Use an 18mm socket and 1/2" ratchet or breaker bar to remove all three bolts.
• Spray penetrating oil around the hub-to-knuckle area if it looks rusty.

Step 7: Remove the hub assembly from the knuckle

• Pull the hub assembly straight out toward you. If it’s stuck, use a hammer to tap on the back flange (rotate and tap evenly) until it breaks free.
• Be careful not to damage the dust shield behind the hub.
• Remove the dust shield, note its orientation, and set it aside.

Step 8: Clean the mounting surface

• Use a wire brush to clean rust and debris from the hub mounting surface on the knuckle.
• Wipe with a shop rag and a little brake cleaner to get a clean, flat surface.
• Apply a very light film of anti-seize compound to the outer edge of the bore to reduce future rusting. Keep it off brake surfaces.

Step 9: Install the new hub assembly

• Position the dust shield back onto the knuckle in the original orientation.
• Slide the new hub assembly into the knuckle, lining up the bolt holes and feeding the axle stub through the center of the hub.
• Start all three hub bolts by hand from the back to avoid cross-threading.
• Tighten the bolts evenly with an 18mm socket and 1/2" ratchet, then torque them to 115 Nm (85 ft-lbs).

Step 10: Reinstall the axle nut

• Install a new axle nut by hand on the axle shaft.
• Have your helper press the brake pedal again or lock the hub with the screwdriver as before.
• Using the 36mm axle nut socket and 1/2" torque wrench, torque the front axle nut to 237 Nm (175 ft-lbs).

Step 11: Reconnect the ABS sensor

• Route the sensor wire along the same path as before.
• Clip it back into its brackets using your fingers or needle-nose pliers.
• Reconnect the electrical connector until it clicks.

Step 12: Reinstall the brake rotor and caliper

• Clean both sides of the rotor with brake cleaner to remove any oil or fingerprints.
• Slide the rotor back onto the hub and install the rotor retaining screw with a T30 Torx bit socket and 3/8" ratchet.
• Remove the caliper and bracket from the hanger and slide it over the rotor.
• Install the caliper bracket bolts with an 18mm socket and 1/2" ratchet and torque to 170 Nm (125 ft-lbs).

Step 13: Reinstall the wheel

• Put the wheel back on and install all lug nuts by hand.
• Snug the lug nuts in a star pattern using a 21mm socket and 1/2" ratchet.
• Raise the vehicle slightly with the floor jack, remove the jack stands, then lower the vehicle fully to the ground.
• Torque the lug nuts in a star pattern to 135 Nm (100 ft-lbs) using a 21mm socket and 1/2" torque wrench.

Step 14: Rear hub notes (if you’re doing the rear)

• The rear process is almost the same: remove wheel, caliper, rotor, ABS wiring, axle nut, and hub bolts, then swap the hub.
• Rear hub bolts typically torque to 115 Nm (85 ft-lbs) and the rear axle nut torques around 237 Nm (175 ft-lbs) depending on axle; follow spec that comes with the part if provided.
• Parking brake shoes are inside the rear rotor; be careful not to damage them when removing or installing the rotor.

✅ After Repair

• Start the engine and slowly move the Grand Cherokee forward and backward a few meters, listening for any grinding or clicking noises.
• Test the brakes at low speed in a safe area to confirm normal pedal feel and stopping power.
• The ABS and traction control lights should stay off; if they come on, recheck the wheel speed sensor connector and wire routing.
• After a short drive (5–10 km), recheck the lug nut torque with the torque wrench.
