Getting Started with Axle Bearing Replacement

Follow these steps for a successful axle bearing replacement:

Gather Tools and Materials | Assemble necessary tools, including a jack, jack stands, wrenches, and new bearings.

Safety First | Park the vehicle on a level surface, engage the parking brake, and support it with jack stands.

Remove the Wheel | Loosen the wheel nuts, raise the vehicle, and remove the wheel.

Disassemble the Brake System | Disconnect the brake caliper and remove it from the rotor.

Remove the Axle Shaft | Unbolt the axle nut, use a slide hammer to remove the axle shaft from the bearing hub.

Remove the Old Bearing | Use a bearing puller to remove the old bearing from the hub.

Install the New Bearing | Use a bearing press to install the new bearing into the hub.

Reassemble the Components | Reinstall the axle shaft, brake caliper, and wheel, following the reverse disassembly steps.

Tighten to Specifications | Torque all bolts to the manufacturer's specifications.

Test Drive | Take the vehicle for a test drive to ensure proper operation.
