The Ultimate Guide to 2010 Ford Focus Wheel Bearings: Diagnosis, Replacement, and Maintenance

Every car owner will experience the need to replace their wheel bearings at some point. If you own a 2010 Ford Focus, this guide will provide you with all the information you need to know about wheel bearing replacement, from diagnosis to maintenance.

Causes of Wheel Bearing Failure

There are various factors that can lead to the failure of wheel bearings. Some of the most common causes include:

• Improper installation: Incorrect installation can cause premature wear and tear on the bearings.
• Lack of lubrication: Inadequate lubrication can lead to friction and heat buildup, which can damage the bearings.
• Excessive weight: Overloading the vehicle can put excessive stress on the bearings.
• Road conditions: Driving on rough or uneven roads can put stress on the bearings.
• Age: Wheel bearings naturally wear out over time.

Symptoms of Wheel Bearing Failure

Here are some common signs that your wheel bearing may be failing:

• Grinding or humming noise: This is usually the most noticeable symptom. The noise may be more pronounced when cornering or braking.
• Wobbling or vibration while driving: You may feel the steering wheel or the entire car wobbling.
• Loose or excessive play in the wheel: You can check this by grabbing the tire at the top and bottom and shaking it.
• Uneven tire wear: Premature or uneven tire wear can indicate a problem with the wheel bearing.

Diagnosing Wheel Bearing Failure

If you suspect that your wheel bearing is failing, it's important to have it diagnosed by a qualified mechanic. The mechanic will typically perform the following steps:

• Physical inspection: The mechanic will look for signs of wear or damage on the wheel bearing and surrounding components.
• Listening for noises: The mechanic will use a stethoscope to listen for any grinding or humming noises coming from the wheel bearing.
• Checking for play: The mechanic will check for excessive play in the wheel bearing by grabbing the tire at the top and bottom and shaking it.

Replacing Wheel Bearings

If the wheel bearing is confirmed to be failing, it will need to be replaced. This is a relatively complex repair that should be performed by a qualified mechanic. The mechanic will typically follow these steps:

• Remove the wheel: The mechanic will loosen the lug nuts and remove the wheel from the vehicle.
• Remove the brake caliper: The brake caliper is attached to the wheel bearing assembly. The mechanic will remove the brake caliper and hang it out of the way.
• Remove the wheel bearing assembly: The wheel bearing assembly is usually held in place by bolts or nuts. The mechanic will remove these fasteners and pull out the assembly.
• Install the new wheel bearing: The mechanic will lubricate the new wheel bearing and install it in the housing.
• Reassemble the hub: The mechanic will reassemble the hub, including the brake rotor and caliper.
• Tighten the lug nuts: The mechanic will tighten the lug nuts to the specified torque.

Special Tools Required

Replacing a wheel bearing typically requires the following special tools:

Maintenance

Wheel bearings, although durable, require regular maintenance to ensure their longevity. Here are some maintenance tips:

• Regular lubrication: The wheel bearings should be lubricated regularly according to the manufacturer's recommendations.
• Inspect the wheel bearing: Inspect the wheel bearing regularly for signs of wear or damage. Look for cracks, pitting, or excessive play.
• Replace the wheel bearing as needed: If the wheel bearing shows signs of wear or damage, it should be replaced as soon as possible.

Inspection Interval

The inspection interval for wheel bearings varies depending on the vehicle and driving conditions. However, it is generally recommended to inspect the wheel bearings every 6,000 to 12,000 miles.

Cost of Replacement

The cost of replacing a wheel bearing varies depending on the vehicle, the severity of the damage, and the location of the repair. However, you can expect to pay anywhere from $200 to $600 for the repair.

Labor Costs

The labor cost for wheel bearing replacement typically ranges from $100 to $250. The labor time varies depending on the vehicle and the mechanic's experience.

Parts Costs

The cost of the wheel bearing itself can range from $50 to $150. The price varies depending on the vehicle and the brand of the bearing.

DIY vs. Professional Replacement

Replacing a wheel bearing is a complex repair that requires specialized tools and knowledge. If you are not mechanically inclined, it is recommended to have the repair performed by a qualified mechanic. However, if you are confident in your mechanical abilities and have the necessary tools, you can replace the wheel bearing yourself.

DIY Steps

If you decide to replace the wheel bearing yourself, follow these steps:

1. Safety first: Park the vehicle on a level surface and engage the parking brake. Chock the wheels to prevent the vehicle from rolling.
2. Gather your tools: You will need the following tools: wheel bearing press, torque wrench, hub puller, bearing separator, new wheel bearing, and grease.
3. Remove the wheel: Loosen the lug nuts and remove the wheel from the vehicle.
4. Remove the brake caliper: The brake caliper is attached to the wheel bearing assembly. Remove the brake caliper and hang it out of the way.
5. Remove the hub: The hub is attached to the wheel bearing assembly. Remove the hub using a hub puller.
6. Remove the old wheel bearing: The wheel bearing is pressed into the hub. Use a bearing separator to remove the old wheel bearing.
7. Install the new wheel bearing: Lubricate the new wheel bearing and press it into the hub.
8. Reassemble the hub: Reassemble the hub, including the brake rotor and caliper.
9. Install the wheel: Install the wheel and tighten the lug nuts to the specified torque.

Tips

Here are some tips for replacing a wheel bearing yourself:

• Use the right tools: The right tools will make the job easier and safer.
• Follow the instructions carefully: Read the instructions that came with the new wheel bearing carefully before starting the repair.
• Take your time: Don't rush the repair. Take your time and do it right.
• If you are unsure, consult a mechanic: If you are not sure how to perform the repair, consult a qualified mechanic.

Interesting Stories and Lessons Learned

Here are some interesting stories and lessons learned about wheel bearing failure:

• The case of the squeaky wheel: One driver noticed a squeaky noise coming from his front wheel. He ignored the noise for a while, thinking it was just a minor issue. However, the noise gradually got louder and more frequent. Eventually, the wheel bearing failed, causing the wheel to come off the vehicle.
• Lesson learned: Don't ignore strange noises coming from your car. Even a minor noise can be a sign of a more serious problem.
• The case of the worn-out wheel bearing: Another driver noticed that his car was pulling to one side while driving. He took his car to a mechanic, who diagnosed the problem as a worn-out wheel bearing. The mechanic replaced the wheel bearing, and the car drove straight again.
• Lesson learned: If your car is pulling to one side while driving, it could be a sign of a worn-out wheel bearing.
• The case of the premature wheel bearing failure: One driver replaced his wheel bearings prematurely because he was not aware of the maintenance schedule. As a result, he spent unnecessary money on the repair.
• Lesson learned: Follow the manufacturer's recommended maintenance schedule to avoid premature wheel bearing failure.

Conclusion

Wheel bearings are an important part of your car's suspension system. They allow the wheels to rotate smoothly and safely. By understanding the causes of wheel bearing failure, the symptoms to look for, and the maintenance required, you can help extend the life of your wheel bearings and keep your car running smoothly.
