• The hub assembly itself.
• Wheel studs (already installed).
• ABS sensor (if applicable, may be pre-installed or separate).
• Sometimes a new axle nut.

Difficulty Level and Estimated Time

• Difficulty: Intermediate
• Estimated Time: 1-3 hours per wheel

Special Tools Needed

• Jack and jack stands
• Wheel chocks
• Socket set and wrench set
• Torque wrench
• Hammer
• Punch or chisel
• Hub puller (may be required)
• Penetrating oil

Critical Steps and Tips

1. Loosen the lug nuts before lifting the vehicle.
2. Secure the vehicle on jack stands.
3. Remove the wheel.
4. Disconnect the ABS sensor (if applicable).
5. Remove the brake caliper and rotor.
6. Remove the axle nut.
7. Use a hub puller to remove the hub assembly from the spindle (if necessary).
8. Install the new hub assembly.
9. Torque the axle nut to the manufacturer's specifications.

DIY or Professional Installation?

• DIY is possible for mechanically inclined individuals with the proper tools and experience. However, professional installation is recommended for those who are not comfortable working on their vehicle's braking system.

Here's a comparison of your hub assembly options:

| Feature | Used OEM Used OEM:

• Pros:
• Genuine factory parts.
• Tested and inspected for quality.
• Significantly lower prices compared to new parts.
• Environmentally friendly by reusing existing components.
• Cons:
• May have some cosmetic imperfections.
• Shorter lifespan compared to new parts (but still reliable).

Refurbished OEM:

• Pros:
• Factory parts professionally restored.
• Often include new components.
• A good balance of price and quality.
• Cons:
• Can be slightly more expensive than used OEM.

New Aftermarket:

• Pros:
• Brand new parts.
• Built to OE specifications.
• Widely available.
• Cons:
• Quality can vary depending on the brand.
• May not last as long as OEM parts.

• Wheel Bearings: Often replaced at the same time as the hub assembly, as they are closely related and experience similar wear.
• Axle Nut: Always replace the axle nut when replacing the hub assembly, as it is a one-time use fastener.
• Brake Pads and Rotors: Inspect and replace if worn, as a faulty hub assembly can cause uneven wear on these components.
• ABS Sensor: If the ABS sensor is faulty or damaged, it should be replaced along with the hub assembly.

Replacing these parts together can prevent repeat failures and save you time and money in the long run. A worn wheel bearing can damage a new hub assembly, and vice versa.

• The typical lifespan of a hub assembly is 80,000 to 120,000 miles.

Factors Affecting Longevity:

• Driving conditions (e.g., rough roads, potholes).
• Driving habits (e.g., aggressive driving, frequent braking).
• Vehicle maintenance (e.g., proper lubrication, timely repairs).
• Quality of the hub assembly.

• Used OEM: $50 - $150
• Refurbished OEM: $80 - $200
• New Aftermarket: $70 - $250
• Labor Cost: $100 - $300 per wheel

Total Job Cost Estimates:

• Used OEM: $150 - $450 per wheel
• Refurbished OEM: $180 - $500 per wheel
• New Aftermarket: $170 - $550 per wheel

• Some BMW models within this year range are known to experience premature hub assembly failure due to the design of the suspension system and the weight of the vehicle.
• Toyota models may experience issues with the ABS sensor failing due to corrosion or damage from road debris.
• Check for any Technical Service Bulletins (TSBs) related to hub assembly failures on your specific vehicle model.

How to Confirm Proper Operation

• Test drive the vehicle at various speeds.
• Listen for any unusual noises, such as grinding, humming, or clicking.
• Check for any vibrations in the steering wheel or floorboard.
• Ensure the ABS light is not illuminated on the dashboard.

What to Look/Listen For

• Smooth and quiet operation of the wheel.
• No excessive play or looseness in the wheel.
• Proper functioning of the ABS system (if applicable).

Q: How do I know if my hub assembly is bad?
A: Common signs include a grinding or humming noise from the wheel area, especially when turning, and excessive play in the wheel.

Q: Can I replace just the wheel bearing instead of the entire hub assembly?
A: While it's sometimes possible, it's often more practical and reliable to replace the entire hub assembly, as the bearing is often integrated into the hub.

Q: Is it safe to drive with a bad hub assembly?
A: It is not recommended to drive with a bad hub assembly, as it can lead to wheel instability and potentially cause an accident.

Q: How often should I replace my hub assemblies?
A: Hub assemblies typically last 80,000 to 120,000 miles, but it's best to inspect them regularly and replace them as needed.

Q: Will a bad hub assembly affect my ABS system?
A: Yes, a faulty hub assembly can affect the ABS system, as the ABS sensor is often integrated into the hub.
