🔧 Front Wheel Bearing Hub Assembly - Replacement

Assumption: This covers the front wheel bearing hub assembly on your 1500. On this truck, the front bearing is serviced as a complete hub assembly, not a press-in bearing.

When the bearing gets noisy, loose, or throws an ABS light, the whole hub assembly is replaced. This is a straightforward job, but the axle nut and brake hardware are tight, so take your time and keep everything clean.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours per side

⚠️ Safety & Precautions

• Work on level ground and support the truck with jack stands; never rely on a jack alone.
• Set the parking brake and chock the rear wheels.
• Do not hang the brake caliper by the hose.
• Disconnect the negative battery cable if you will unplug ABS wiring for a long time.
• The axle nut is very tight; keep the truck on the ground while breaking it loose.
• Use care around ABS wiring at the hub.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the wheel and axle nut

• Use a breaker bar with a 1-7/16 inch socket to loosen the front axle nut while the truck is still on the ground.
• Use a 19mm socket to loosen the wheel lug nuts slightly.
• Do not fully remove the axle nut yet.

Step 2: Raise and secure the truck

• Use the floor jack to lift the front corner.
• Place the truck on jack stands and make sure it is stable.
• Remove the wheel using the 19mm socket.

Step 3: Remove the brake caliper and rotor

• Use a 13mm socket to remove the caliper slide bolts.
• Lift the caliper off and hang it with support so the hose is not stretched.
• Use a 15mm socket to remove the caliper bracket bolts if needed for rotor removal.
• Remove the rotor by hand; if stuck, tap it with a rubber mallet.

Step 4: Remove the axle nut and ABS connector

• Remove the axle nut with the 1-7/16 inch socket.
• Unplug the ABS sensor connector from the hub area, if equipped.
• Use a small screwdriver if the clip is tight.

Step 5: Remove the hub-to-knuckle bolts

• Use a 21mm socket and ratchet or breaker bar to remove the three hub mounting bolts from the back side of the steering knuckle.
• If the hub is seized, apply penetrating oil and work it loose with a pry bar and rubber mallet.

Step 6: Remove the old hub assembly

• Pull the hub assembly straight out of the knuckle.
• Clean the mounting surface with a wire brush and brake cleaner.
• A clean surface helps the new hub seat fully.

Step 7: Install the new hub assembly

• Set the new hub assembly into place and start the bolts by hand.
• Use the 21mm socket to tighten the hub bolts evenly.
• Torque to 148 Nm (109 ft-lbs).
• Reconnect the ABS sensor connector.

Step 8: Reinstall the axle nut, rotor, and brakes

• Install a new axle nut by hand first.
• Use the 1-7/16 inch socket and torque wrench to tighten the axle nut.
• Torque to 203 Nm (150 ft-lbs).
• Reinstall the rotor.
• Reinstall the caliper bracket with the 15mm socket and torque to 237 Nm (175 ft-lbs).
• Reinstall the caliper slide bolts with the 13mm socket and torque to 32 Nm (24 ft-lbs).

Step 9: Reinstall the wheel

• Install the wheel and snug the lug nuts with the 19mm socket.
• Lower the truck and then torque to 176 Nm (130 ft-lbs).

✅ After Repair

• Start the truck and check for ABS warning lights.
• Spin the wheel by hand before lowering fully to make sure nothing rubs.
