I am going to attempt to change the wheel bearing or hub asssmbly on my car.

My car has been runnnng very loud from the inside for about 4 months now. A mechanic told me it was my wheel bearings. I looked myself a saw that it makes a grinding noise when I spin the wheel and the tire is bald on one side and good on the other. Also, some brake light has been on in my car for over a year and I haven't thought anything of it. Would changing the hub assembly turn the light off? Or should I replace the abs sensor too? Also, should I replace just the bearing or the whole hub assembly?

Thank you!

How to Identify and Fix Common car Problems ?

A wheel bearing isn`t often considered an ABS component, but it directly involves it and, if failed, will throw the system into error mode. If a wheel bearing is significantly worn to the point where the wheel can wobble about its axis, more than likely, an ABS speed sensor code will be stored.
On many modern cars, a bad wheel bearing will trigger a warning light. The ABS or traction control warnings will often illuminate, since a bad bearing will trip the system to deactivate.
This is due to the difference in signal strength from the wheel speed sensors (WSS) side to side. The problem is usually associated with the air gap difference or wiring and/or connector integrity. In many cases, removing the WSS from the other side, if possible, and cleaning the mounting surface may repair problem.
In many cases, replacing one hub bearing will cause the driver to feel ABS false activation when coming to a slow stop on dry pavement. False activation is usually described as a pulse in the brake pedal when not expected. The pulsation comes from the ABS valves cycling the supposedly locked-up wheel.
The four common reasons that typically cause this light to turn on include a malfunctioning ABS module, low levels in the fluid reservoir, broken wheel speed sensors, or the system is turned off. Your ABS actually shares some important components with another system in your vehicle: your traction control system.
If both the ABS and the brake system light come on at the same time, your vehicle is no longer safe to drive. This means there is a serious problem with the car`s braking system and continuing to drive puts yourself and others at risk.
Why do ABS sensors fail? Given its position, the reluctor wheel or tone ring can easily become dirty or damaged. Similarly, dust can collect on the sensor. Both could result in an erratic, or even no signal at all.
Occasionally, these sensors can fail or become faulty working intermittently sending inaccurate signals to the ECU. In your case it may be possible that the transmission is receiving a faulty signal from the ABS system.
You can expect an ABS sensor to last 30,000 to 50,000 miles. If the sensor does fail, you should receive an ABS warning light on the dash, and your anti-lock braking system will not engage when needed.
Unless the ABS system is actually activating, that system would not be implicated as a “cause” of the poor acceleration. In any event, once the ABS codes are read by the mechanic using a scanner, it will be evident what is wrong with that system.
Removing a wheel speed sensor will disable ABS—and sometimes, stability control. If your car has a yaw sensor, you can unplug that for results. You can also try simply unplugging the ABS module, though that could adversely affect your car`s braking performance.
If this sensor gets dirty, it can cause the ABS light to turn on, indicating a problem when none actually exists. In general, sensors that work with the engine impact the performance when they get dirty. The engine may sound rough, not run as well, or have less efficiency or power.
All you have to do is connect the device to your OBD2 carport and run an ABS test. From there, you will have a clearly identified trouble code about what is wrong with the ABS. With this pinpointed information, you can easily diagnose and fix the issues with your vehicle.
Where are these sensors located? The ABS sensor is typically located in each wheel hub/rotor on a four channel ABS system. Some rear wheel drive applications have the sensor mounted in the rear differential.
Blown Fuse or Stuck Bulb

Sometimes a blown fuse to the ABS can cause the light to come on and stay on. Fuses are easy to blow, so sometimes it`s an easy fix to check.

If the ABS system detects that one wheel is slowing down more rapidly than the rest (a symptom of wheel-lock) it automatically reduces the brake pressure on this wheel by opening a pressure release valve in the hydraulic system. ABS also has the ability to build the pressure back up via the hydraulic motor.
ABS module repairs can be done right in your driveway. Competitive, upfront pricing. Professional, ASE-certified technicians perform the repairs. All repairs and maintenance are performed with high-quality equipment and replacement parts.
A failing wheel speed sensor will turn off your vehicle`s traction control, stability control, or any other driver assist feature. Sometimes, a damaged wire could also prevent the sensor from sending data to the control module.
The ABS controller may make noise that sounds like grinding or buzzing. In some vehicles, you may feel a slight vibration. It is important to keep your foot on the brake pedal when you hear noise or feel pulsations.
This component, which is also referred to as an ABS sensor, is attached to the hub of a drive tire and is responsible for monitoring multiple vehicle functions such as traction control, anti-lock braking systems, and obviously, the vehicle`s speed.
Transmission Range Sensor (TR)/ Transmission Position Sensor

The PCM uses this information to control which gears of the transmission to enable or disable. When the TR sensor fails it can cause wrong gear starts, no upshifts, or what feels like a falling-out-of-gear condition.

1) Your pedal vibrated because the ABS (anti-lock braking system) was activated. If the pedal vibrations (pulsing and groaning noises, too) happened when you e-braked, chances are ABS was activated. ABS prevents your tyres from locking up, which could lead to an uncontrollable skid.
It`s very dangerous to be out on the road when you know your ABS system isn`t working, regardless of the reason. If you cause a crash and knew about the faulty sensor, you could have greater liability for the damage.
In order to operate, your ABS system needs electricity. This is controlled by the anti-lock fuses and relay. The first fuse (a 10 amp fuse) must be good in order for electricity to flow to the relay, and the relay must function to provide power to the second fuse (a 30 amp fuse).

I hear an abnormal noise from front driver’s side wheel. It sounds like a wheel bearing but not sure.
ANSWER : A wheel bearing noise can be different between vehicles as some designs may vary a little. The most common is a roaring noise that may change when going around turns. It may be louder going in one direction or the other or just make a loud noise all of the time. The wheel hub presses into the wheel bearing. The hub is where the studs are for the wheel to be bolted onto the steering knuckle and the bearing provides the support for the wheel and weight of the vehicle. Consider hiring an experienced technician like one from YourMechanic who can come out and take a closer look at your wheel bearing noise to offer a more personal diagnosis.

my car is making a knocking sound on the left front wheel when driving on bumpy road. I changed wheel bearing and my mechanic cant
ANSWER : A banging or rattling over bumps can be caused by several different suspension components. A worn strut can make noises as can the upper strut mount. The strut mount allows the strut assembly to turn and move up and down. If the strut mount is worn, it can allow the strut assembly to rattle or bang over bumps. Stabilizer bar end links or bushings can also contribute to a banging noise. Worn end links can allow movement in the bar, and the bushings where the bar connects to the chassis can wear away and allow the bar to contact the chassis. Even a worn tie rod or ball joint can cause noises over bumps.

Since so many components can be causing a noise over bumps, have a certified technician inspect the suspension to isolate the exact cause.

Shifting from 2nd to 3rd, car stopped going fast. Now it won’t go at all.
ANSWER : It is possible that your clutch has failed. The sound you are hearing is likely due to the clutch not engaging with the engine due to it being worn. I would recommened having your transmission inspected by a qualified transmission expert to determine if your clutch requires replacement in order to resolve this issue. This inspection may require removal and partial disassembly of the transmission in order to verify that the clutch has failed.

ANSWER : What you are describing sounds like free play in the tie rods. Your car has enough miles on it for this to be a problem. The tie rods are the link between the steering gearbox and the front wheels and as they wear, they will develop a certain amount of free play. There are about six pieces there that can be replaced as needed to tighten things up again. You can contact Your Mechanic to have a technician come out to your home or office to check out your front end and advise you on which pieces need to be replaced. Don’t put this off too long. Eventually, a worn tie rod can separate, if that happens, you will lose control of the car.

ANSWER : Hi there. When a car is slow to accelerate it can be caused by multiple issues, ranging from fuel systems that are clogged or damaged to an ignition system component failure. It is also possible that something in the driveline system is dragging which causes the lack of acceleration. Since there are so many different possible issues, the best way to start the diagnosis process is to have a professional mobile mechanic from our team come to your location and complete a car is slow to accelerate inspection.

I am having a problem fixing my left rear wheel bearing and hub assembly
ANSWER : Hello there, thank you for asking about your 2010 Hyundai Veracruz. You should have loosened the rear parking brake shoes using the access hole on the rotor. The parking brake shoes can hold the rotor/drum on and will not separate. If you need help from a certified mechanic, have a technician from YourMechanic replace your rear wheel bearings at your home or office.
