🔧 Wheel Bearing - Replacement

Assumption: this is the front hub bearing assembly. On your A4, the bearing is part of the hub assembly and is usually replaced as a unit, not pressed apart. A worn bearing can cause humming, growling, looseness, or ABS warning lights.

Difficulty Level: Advanced | Estimated Time: 3-5 hours per side

⚠️ Safety & Precautions

• Support the vehicle with jack stands; never rely on a jack alone.
• Your Camry Hybrid has high-voltage systems. No HV battery disconnect is needed for this job, but keep the ignition off and key fob away from the car.
• Brake components may be hot if the car was just driven.
• Do not hang the brake caliper by the hose.
• Be careful with the wheel speed sensor wiring so you do not damage ABS wiring.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the vehicle

• Loosen the lug nuts with a 21mm lug wrench or socket.
• Lift the car with a floor jack (rated 3-ton minimum).
• Set it down on jack stands and chock the rear wheels.

Step 2: Remove the wheel and brake parts

• Remove the wheel with the 21mm socket.
• Use a 12mm socket or 14mm socket to remove the caliper bolts, depending on the side and fastener style.
• Hang the caliper with a bungee cord or caliper hanger.
• Remove the brake rotor. If it is stuck, tap it gently with a hammer.

Step 3: Remove the axle nut and sensor components

• Use a 19mm socket and breaker bar to remove the axle nut.
• Disconnect the wheel speed sensor connector with a 10mm socket if the harness is attached to the knuckle.
• Carefully unclip the sensor wire so it is out of the way.

Step 4: Separate the knuckle from the hub area

• Remove the hub-to-knuckle bolts using a 17mm socket or 19mm socket.
• If the hub is rusted in place, spray penetrating oil around the flange and let it soak.
• Use a hammer and punch to tap the hub free evenly from the knuckle.

Step 5: Install the new hub bearing assembly

• Clean the mounting surface with wire brush and brake cleaner.
• Set the new hub bearing assembly in place by hand.
• Install the new hub bolts and snug them with a 17mm socket or 19mm socket.
• Torque to 70 Nm (52 ft-lbs) for the hub bolts.

Step 6: Reassemble the brakes and axle

• Reinstall the rotor and caliper using the 12mm socket or 14mm socket.
• Install a new axle nut and snug it with a 19mm socket.
• Torque to 216 Nm (159 ft-lbs) for the axle nut after the vehicle is back on the ground.
• Torque to 34 Nm (25 ft-lbs) for the caliper bolts unless your brake hardware label specifies otherwise.

Step 7: Reinstall the wheel

• Put the wheel back on and hand-tighten the lug nuts.
• Lower the vehicle and torque the lug nuts with a torque wrench.
• Torque to 103 Nm (76 ft-lbs) for the lug nuts.

✅ After Repair
