Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Socket set
- Torque wrench
- Slide hammer or bearing puller
- Hammer
- Grease
- Bearing press (if needed)
Sub-steps:
1. Park the vehicle on a level surface and engage the parking brake.
2. Disconnect the negative battery terminal to ensure safety.
3. Remove the wheel hub cover (if applicable).

2. Remove Wheel and Brake Assembly

Loosen the lug nuts using a lug wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.
Remove the brake caliper using a socket set; hang it safely without stressing the brake line.
Remove the brake rotor from the hub assembly.

3. Remove Hub Assembly

Remove the axle nut using a socket set, and set it aside.
Disconnect any ABS sensors or wiring harness attached to the hub.
Use a slide hammer or bearing puller to remove the hub assembly from the spindle.
Clean the area where the new hub will be mounted.

4. Install New Wheel Bearing

If the new wheel bearing is part of a complete hub assembly, align it with the spindle and press it in place using a bearing press if necessary.
If replacing just the bearing, ensure proper orientation and alignment, then press the new bearing into the hub assembly.

5. Reassemble Components

Reinstall the hub assembly onto the spindle and secure it with the axle nut, torquing it to the manufacturer's specifications (typically around 150 lb-ft).
Reattach any ABS sensors or wiring harness.
Reinstall the brake rotor and caliper, ensuring all fasteners are tightened properly.
Mount the wheel back onto the hub, hand-tightening the lug nuts.

6. Final Checks

Lower the vehicle back to the ground and torque the lug nuts to the manufacturer's specifications (usually around 140 lb-ft).
Reconnect the negative battery terminal.
Test the brakes and wheel movement before driving.
