Wheel bearings enable the wheel to rotate smoothly with minimum friction. When damaged, they may cause the wheel to stop while driving thus putting your safety and that of other motorists at risk. More so, a damaged wheel bearing usually puts a lot of stress on the CV joint, the hub, and the transmission. That is why it is important to replace a bad wheel bearing on time. Some mechanics usually recommended that you should break in a new wheel bearing to polish the raceways and extend the bearing maintenance cycle. But, do new wheel bearings need to be broken in? Continue reading to find out. Do New Wheel Bearings Need to Break In? YES, a new wheel bearing needs to break in. Wheel bearing break-in refers to the period of adjustment between the bearings and the surface that they rub. This procedure helps to give the bearings time to adjust and operate evenly after installation. It ensures that the bearings are not put under excess stress early on during operation.  Breaking in a new wheel bearing helps to ensure that they are well-conditioned. The break-in period gives the wheel bearing crucial time to adjust for optimal performance and longevity. It allows the bearings to be well lubricated to minimize friction during operation. It also allows the bearing to sit correctly thus preventing uneven wear. A proper wheel bearing break-in will: How Long Does it Take to Break in Bearings? There is no set amount of time that wheel bearings take to break in. This is because many factors determine how long it takes for bearings to break in. Some of these factors include; driving conditions, type of bearing, lube application, car model, how much time you spend behind the wheels, and much more. Some wheel bearings may take a shorter period to break in (a few hours) while others take long (more than a week) before they break in.  But on average, it takes about 3 days for wheel bearings to break in. If you want your wheel bearings to break in within a short period of time, ensure that you lubricate them well. Proper placement of lubrication will reduce excessive friction and resistance. It will also ensure that the bearings sit in the right place and spin them fast and for a longer period thus reducing the break-in time. What Happens if You Don’t Break in New Wheel Bearings? Proper break-in of wheel bearings helps to prevent premature wear. So, if you don’t break in the new wheel bearings, they will wear out fast, meaning they will not last for long. And, because new wheel bearings are not well conditioned, they will put a lot of stress on the CV joint, the hub, and the transmission. Other issues that can occur when you don’t break in new wheel bearings include ABS and braking issues, seal leakage, and wheel wobbling. Do You Need to Lube New Bearings? YES, you need to lube new bearings. Lube not only helps the wheels to spin easily but also protects the bearings from water and other road contaminants. As pointed out earlier, wheel bearings are a very important safety feature in your car. If they are not well lubricated, they will wear out quickly and over time fail to perform their job properly. Wheel bearing lubrication is vital in preserving their lifespan and performance. A suitable lube should be applied on the wheel bearings, the housing, and the wheel end inside the surface where the bearings sit. This will help to prevent wear and tear, friction, and corrosion.  Most wheel bearings are usually lubricated from the factory. However, you should inspect them again before installing them and lube them again if you spot any sign of contamination like water or dust. Proper lubrication will also help the bearings to sit properly on the raceway for smooth operation. Conclusion Do new wheel bearings need to be broken in? YES, they need to be broken in. This crucial process will not only help to enhance their performance and longevity but will also promote your safety. Wheel bearing break-in is a crucial procedure that should be done to give the bearing much-needed time to adjust and perform efficiently thereafter.

It is challenging to find a non-computerized car today. Modern manufacturers equip vehicles with hi-tech systems that can mitigate a lot of car defects. These computerized systems signal car dashboards when problems occur and ease the troubleshooting process. The vital question, therefore, to ask ourselves is, can a wheel speed sensor cause limp mode? Can a Wheel Speed Sensor Cause Limp Mode? When a faulty wheel speed sensor sends wrongful signals to the car ABS, the car computer system will activate the limp mode to protect other essential components. This will disable certain car functions, such as shutting down the AC. Faulty wheel speed sensors send wrong signals to the ABS control unit. This generates a trouble code which will indicate a trouble light. In case you suspect a defective sensor make the following diagnosis; What is a Wheel Speed Sensor? A wheel speed sensor or a vehicle speed sensor is an electronic gadget used to monitor the rotational speed of a vehicle wheel. It sends the information to the vehicle’s anti-lock braking system (ABS). The wheel speed sensor is essential in controlling brakes and ensures the stability of a car. It is usually mounted on the wheel hub and sends the information it receives to the vehicle computer. The vehicle computer uses the wheel speed sensor data to adjust its brake system to ensure a smooth stop. A limp mode is a state in which the vehicle’s computer system detects a fault in the engine, reducing engine operation to provide safety and reduce further engine damage. A car in limp mode will minimize power mode to limit the output of power to safeguard the engine and other components from further damage. How Wheel Speed Sensors Work All the wheels of a car are usually attached to wheel speed sensors. The sensors are made of an electromagnetic induction sensor head and magnetic ring gear of ferromagnetic material. The wheel speed sensor’s function is to monitor and relay the wheel speed data to the ABS control unit of a car. The wheel sensor detects the wheel rotation frequency and calculates it to the vehicle speed, which converts the information into signals. Once received, it is interpreted by the ABS computer system to activate a different set of actions on the vehicle. Various Types of Wheel Speed Sensors There are two main types of wheel speed sensors passive and active sensors. These types of sensors send analog signals in alternating voltage form to the ABS control unit, where they are analyzed and utilized. Each wheel of the vehicle creates a unique AC signal. These signals can only be active when the wheel’s rotational speed is fast. They do not read at a low rotational speed. These sensors can detect the rotational direction of the wheel and record the signals using a magnetic pulse sensor. They function in various temperatures and provide output to the ABS in digital signal form. The ABS and other car systems use the information provided. Active wheel speed sensors are not as sensitive as passive sensors. How Limp Mode Works The limp mode shields important car components when the car computer system detects faults in the engine that could cause further damage. When the limp mode is active, the car’s engine will be limited to certain functions. Some common causes of limp mode are blocked air filters, faulty vehicle sensors such as wheel speed sensors, inadequate vehicle fluids or oils, and failed transmission. Consequences of Driving With a Faulty Wheel Speed Sensor A vehicle wheel speed sensor is essential to ensure users’ safety. It works with the ABS to provide a car that can have an emergency brake smoothly. A broken sensor can cause you to lose control of your vehicle and cause a crash. Broken wheel speed can make the entire ABS not function correctly, impacting other systems in the car, such as traction control and stability. Inaccurate reading of the vehicle speed is another effect of driving a car with a faulty wheel speed sensor leading to increased fuel usage. Common symptoms of a faulty wheel speed sensor The first warning signs that your wheel speed sensor may be faulty are; Conclusion The wheel speed sensor of a vehicle is an important safety feature. A glitch in the sensor can cause defects in other vehicle functions leading the car to limp mode. Constantly consult your mechanic to check your vehicle speed sensors to avoid further damage to your engine and protect you from losing control over your car and causing accidents. To ensure your wheel speed sensors are correctly functional, clean them regularly, and check for damage and wiring.
