43550-KK010 Front Wheel Hub Bearing Assembly For 43550KK010 Toyota Hilux Revo GUN125 GUN126

Product Function Description

The front wheel hub bearing assembly is a critical component of your Toyota Hilux Revo‘s front axle and 4WD system. This third-generation integrated hub unit combines the wheel hub, bearing, and ABS sensor ring into a single pre-assembled unit, supporting the front wheels while allowing smooth rotation and maintaining proper wheel alignment . For the 8th generation Toyota Hilux Revo GUN125 and GUN126 4WD models (2015-present), a properly functioning hub assembly is essential for safe driving, stable handling, and reliable off-road performance. This component is designed to factory specifications, ensuring proper fit and reliable front axle operation.

Common Symptoms of a Failing Wheel Hub Bearing

If you are experiencing any of the following symptoms, your wheel hub bearing assembly may be failing and in need of replacement :

• Whining, roaring, or grinding noise: Noise from the front wheels that increases with vehicle speed, especially noticeable at 40-80 km/h – this indicates bearing wear

• Vibration through steering wheel or floor: Front wheel vibration felt through the steering wheel or floor that changes with speed

• Excessive play in the front wheel: Wobble or play when the wheel is lifted and checked at 12 and 6 o'clock positions

• Uneven or rapid tire wear: Abnormal or accelerated wear on the front tires

• ABS warning light illuminated: The dashboard ABS light comes on – this may indicate a damaged or faulty ABS sensor ring integrated into the hub

• Grease leakage: Visible grease or oil around the hub area

• Vehicle pulls to one side: The vehicle drifts during driving, indicating bearing or hub misalignment

If you have confirmed these symptoms through inspection, replacing the wheel hub bearing assembly is the recommended solution.

Product Specifications

Package Contents

Common Misconceptions About Wheel Hub Bearings

Myth 1: "If it's not making noise, the bearing is fine."
Fact: Hub bearings can fail without making significant noise. Regular inspection for play and proper maintenance is essential.

Myth 2: "Only one side needs replacing."
Fact: If one wheel bearing has failed or is showing signs of wear, the opposite side is likely also worn and should be replaced at the same time for balanced performance.

Myth 3: "Any wheel bearing will fit."
Fact: This is a vehicle-specific hub unit. Using the correct part ensures proper ABS function, bearing preload, and safe operation. This is a 3rd generation integrated hub unit – not a separate bearing.

Common Customer Concerns & Our Solutions

We understand that purchasing a wheel hub bearing assembly can raise questions and concerns. Here is how we address the most common issues our customers face:

"How do I know if the noise is from the wheel bearing and not the tires?" – Bearing noise typically changes with speed, not road surface, and often gets louder when turning left or right. Tires tend to make noise on certain road surfaces. If the noise changes when you turn the steering wheel slightly, it's likely the bearing.

"If I replace the hub assembly, will the ABS warning light go away?" – If the ABS light is caused by a damaged tone ring in the hub, replacing the hub will resolve the issue. However, we recommend having the ABS codes cleared after installation.

"What if the part arrives damaged or doesn't meet quality expectations?" – Every shipment is inspected before dispatch, and we stand behind our products with a quality assurance policy. If a part ever arrives defective, we'll arrange a replacement immediately.

Related Product Recommendations (Extended)

When replacing the front wheel hub bearing assembly on the Toyota Hilux Revo, it is often recommended to inspect and consider replacing the following related components at the same time.

Axle Nut – The axle nut is a critical component that secures the hub to the drive shaft. On many Toyota models, the axle nut is a single-use part that must be replaced each time the hub is removed. Always use a new nut and torque to specification.

Front ABS Wheel Speed Sensor – The ABS sensor reads from the encoder ring integrated into the hub. If the sensor is damaged or contaminated, it can trigger the ABS warning light. Inspect the sensor for damage and clean the mounting surface during hub replacement. For Hilux Revo, the sensor is accessible and should be carefully handled to avoid damage.

Front Brake Rotor – The brake rotor mounts to the hub. If the rotor is worn, scored, or warped, it should be replaced while the hub is being serviced. Warped rotors can cause vibration during braking that may be mistaken for bearing issues.

Front Brake Pads – Inspect the brake pads for wear. If the pads are worn thin or if there is uneven wear, replace them. Contaminated pads from grease or brake fluid should always be replaced.

Lower Ball Joint – The ball joint connects the steering knuckle to the lower control arm. Worn ball joints can cause play that may be confused with bearing play. Inspect for movement when the hub is removed.

Tie Rod End – The tie rod end connects the steering rack to the steering knuckle. Worn tie rod ends can cause steering play and vibration. Inspect while the wheel is removed.
