A car wheel bearing is a crucial component of a vehicle's wheel assembly that enables smooth and efficient rotation of the wheel while driving.

Excessive load or impact: Intense driving conditions, such as carrying heavy loads or encountering potholes and impacts, can put additional stress on the wheel bearing. This can lead to damage, wear, and ultimately noise.

Airbus TETRA systems connect analogue and digital group call services using the Generic Four Wire interface. There is an interface for one-to-one calls for connecting to an organisation's PABX, to PSTN or cellular networks, and interfaces for connecting SDS (the “TETRA text messages”) with cellular networks and IP data traffic with data networks.

Depending on the vehicle’s design, there may be one or two wheel bearings per wheel. In a front-wheel-drive vehicle, each front wheel usually has a wheel bearing assembly, while rear-wheel-drive vehicles may have wheel bearings in the front and rear wheels.

The TW1m voice and data modem equips you with a powerful device to transfer voice and data over TETRA. Benefit from high availability, robust security and low energy consumption.

It’s worth noting that the specific location and design of bearings may vary slightly between different vehicle models and manufacturers. It is recommended to consult the vehicle’s manual or visit a trusted local garage for an accurate assessment and information regarding your specific car’s wheel bearing location – and what is needed to fix it.

In most vehicles, the wheel bearing is a sealed unit that is pressed into the hub assembly. It is positioned between the inner and outer bearing races, which are the metal rings that contain the steel balls or rollers.

If you’re looking at how to buy TETRA radios for your organization or for your network, this document is a good place to start.

It's advisable to check with local automotive parts suppliers or contact a trusted local garage to get more accurate pricing information specific to your vehicle.

Each device and accessory we provide has unique features and benefits that are tailored to various mission-critical requirements. Choose the best device for you with support from Airbus.

If you can hear a strange noise coming from your wheels – it could be an issue with your wheel bearings. It could also indicate a serious issue.

The TH1n slimline TETRA radio is a pocket-sized, powerful device often used by professional users who welcome a smaller radio, such as private security and healthcare staff.

If you suspect a faulty wheel bearing, it is essential to have it inspected and repaired by a qualified mechanic. Ignoring a worn or damaged wheel bearing can result in further damage to the wheel assembly and compromise the safety and performance of your vehicle. Alternatively, take your vehicle to your local garage to get the problem resolved.

We have a wide range of devices suited to several mission-critical situations, and our extensive accessories catalogue gives you the freedom to customise your devices to further meet your unique needs.

A TETRA network is nothing without its devices. Ease of use, size and features are all considerations when it comes to choosing the right device for your needs. Make the right choice with us.

Coverage depends mostly on the frequency used and the transmission power. As TETRA is an open standard, competing vendors have continuously brought innovation to TETRA’s development so that today, using the same frequency band with similar output power, TETRA coverage is outstanding.

There’s an ever-growing trend among professional organisations to use smartphones to take advantage of broadband and multimedia communications. The main reason for this is to expand the critical communications service for those who communicate via smartphone. Economical reasons are a strong factor in this, as it’s more cost-effective than going directly to broadband-based critical communication (4G/5G).

Airbus is committed to maintaining these systems for years to come. This guarantees that the TETRA system develops for a long time.

Lack of lubrication: Adequate lubrication is crucial for the smooth operation of a wheel bearing. If the bearing is not properly lubricated or the lubricant has deteriorated over time, it can result in increased friction and noise.

Wear and tear: Over time, bearings can wear out due to constant use and exposure to various road conditions. When they become worn, the metal balls or rollers inside may lose their smoothness, causing friction and generating noise.

For users constantly on the move, the TETRA mobile radio TMR880i is a sturdy mobile radio that you can set up inside your vehicle to boost communication capabilities on the move.

The bearing is typically mounted within a hub assembly or wheel hub, which connects the wheel to the vehicle's suspension system.

Our TETRA devices and accessories meet rigorous industry standards to meet the varying requirements of professional users.

Replacing a car wheel bearing typically involves several steps and requires some mechanical knowledge and tools. Here's a general overview of the process:

Whether you need waterproof equipment, special use case add-ons or hands-free communication, our accessories can get you there.

Mission-critical users, consisting of all public safety and security segments, commonly use the TH9 TETRA radio. Transportation services and airport staff also use this device.

The car wheel bearings are located within the wheel hub assembly. This is the part that connects the wheel to the vehicle's suspension system.

It is highly recommended to consult your vehicle's repair manual, call a mobile mechanic or seek professional assistance from a local garage.

As a rough estimate, the price for a single wheel bearing can range from £150 to £250. However, this is only an approximate range, and the actual cost can be higher or lower depending on the factors mentioned above.

It's crucial to note that these are general guidelines, and the specific steps and procedures can vary depending on your vehicle's make and model.

A common issue for most car owners relates to the car wheel bearings. But what are they? Why are they important? And can you replace them yourself?

There are apps that put a PTT button on the smartphone screen. Some smartphone models may also have a physical button that could be dedicated to the PTT function. This is great for many users, especially when the push-to-talk application is designed for professional use.

When you work with Airbus, you can be safe in the knowledge that you’re working with a provider with decades of critical communications experience.

Common signs of a failing wheel bearing include unusual noises such as grinding or humming coming from the wheel, vibration, uneven tyre wear, and excessive play or looseness in the wheel.

What's more, you can adopt smartphones and other broadband solutions and connect them very effectively to Airbus TETRA systems. Such hybrid solutions are a smooth way to mission-critical broadband.

Contamination: Dirt, debris, or water can enter the wheel bearing and cause contamination. This can accelerate wear and create noise as the foreign particles interfere with the smooth rotation of the bearing.

The cost of a new car wheel bearing can vary depending on several factors, including the make and model of your vehicle, the location of the bearing, and whether you purchase an original equipment manufacturer part.

Keeping on top of regular car maintenance and getting your car serviced can help avoid this issue affecting your vehicle.

Keep in mind that if you're replacing a wheel bearing, it's usually recommended to replace both bearings on the same axle simultaneously, even if only one is showing signs of wear or damage.

If a wheel bearing is damaged or worn, it should be replaced promptly to ensure safe operation of the vehicle and prevent further damage to other components.

Improper installation: If a wheel bearing is not installed correctly during maintenance or repair, it can lead to premature wear and noise. Improper installation can result in misalignment or insufficient torque, causing the bearing to wear unevenly.
