What to do when your abs light comes on after a wheel bearing is replaced?

If you have an ABS light on after wheel bearing replaced, you may have to also replace the other wheel bearing hub. Car makers sometimes install the toothed tone ring inside the wheel bearing hub and mount the wheel speed sensor on the outside of the hub.

What should I do if my abs is not working?

Repair Procedure: If you diagnose a bad hub bearing on one side of a vehicle and the ABS wheel speed sensor or tone ring is integral to the bearing, you may need additional repairs to restore proper ABS functioning.

Why is my ABS brake light not working?

An error occurred while retrieving sharing information. Please try again later. If you have the old-style ABS brakes with the metal ring, it’s a possibility you might have damaged the ring when you replace the wheel bearing or installed the sensor improperly. Also, check the sensors for debris build-ups like road grime or axle grease.

Can a new wheel bearing cause false activation?

The new bearing will have little to no play; the remaining hub has acceptable play, but can still affect signal strength. Again, the difference in signal from side to side may be enough to trigger false activation.

Can a wheel bearing hub be replaced on one side?

Vehicle had wheel bearing hub replaced on one side. If you diagnose a bad hub bearing on one side of a vehicle, and the ABS wheel speed sensor or tone ring is integral to the bearing, you may need additional repairs to restore proper ABS functioning.

The new bearing will have little to no play, and the remaining hub will have acceptable play, but can still affect signal strength. Again, the difference in signal from side to side may be enough to trigger false activation. If WSS are integral and not serviceable, replacing the hub bearings in pairs may be the only answer.

What makes the ABS brake light come on?

The new style ABS systems uses a magnetic encoder built into the wheel bearing, and if the wheel bearing is installed backwards with the encoder facing out, it won’t take long before your ABS light is on and your stress level goes up.

When does the ABS and traction control light come on?

The ABS Light activates once your car’s computer detects this problem. If a fuse blows, the PCM picks up the signal and activates the ABS light, along with the Check Engine Light, to notify you that a problem has occurred.

When does the ABS brake light come on?

If any of the teeth are damaged or missing, the ABS brake light will come on, warning the driver of a problem. The new style ABS systems use a magnetic encoder built into the wheel bearing, and if the wheel bearing is installed backward with the encoder facing out, it won’t take long before your ABS light is on and your stress level goes up.

Why is my abs and traction control light on?

Your car has sensors that monitor wheel speed and constantly relay information to the ABS and Traction Control system. When any of your tires have low tire pressure, the ECU ends up sensing an abnormal speed. It may send off inaccurate or flawed information to the ABS or Traction Control, which inadvertently activates their warning signals.

What causes an ABS sensor to turn on?

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.

Where is the ABS speed sensor located on a car?

The ABS wheel speed sensor is located at the wheel, behind the brake rotor but some are placed directly on the axle. Each vehicle contains a varying amount of ABS wheel speed sensors.

Why are wheel bearing hubs equipped with wheel speed sensors?

When engineers came up with the idea of putting the wheel speed sensor (WSS) and tone ring inside a sealed wheel bearing hub assembly, it seemed like a great idea. The sealed environment would help protect the sensor and make it less vulnerable to damage or contamination from the outside.

The ABS wheel speed sensor is located at the wheel, behind the brake rotor but some are placed directly on the axle. Each vehicle contains a varying amount of ABS wheel speed sensors.

What do you do when a wheel bearing hub is rusting?

This rusting process is called rust jacking. Sometimes you can remove the sensor, sand off the rust, and re-install the sensor. But other times you must install a new wheel bearing hub. After installation, you may think you’ve solved the problem.

Can a wheel bearing be replaced on an ABS system?

The new style ABS systems use a magnetic encoder built into the wheel bearing, and if the wheel bearing is installed backward with the encoder facing out, it won’t take long before your ABS light is on and your stress level goes up. The sad part is, you will most likely have to replace the wheel bearing with a new one.

What causes an ABS light to come on after a hub replacement?

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. Vehicle had wheel bearing hub replaced on one side.

What kind of seal does a front wheel hub need?

1. Quad-Lip Inboard Seal to provide optimal moisture protection 2. Molded Grommet to protect ABS cable and ensure integrity of the Traction Control and Anti-Lock Braking Systems 3. Primary Outboard Seal to protect components from mud, sand and road chemicals 4.

Why are front wheel hub assemblies Moog parts?

Where quality is critical, it has to be MOOG. Hub assemblies are critical for safe and reliable operation of a vehicle — and they’re subject to some of the harshest punishments the road can dish out.

Why is my abs light on and Trac off?

Here’s why: Older ABS braking systems used a steel toothed ring and a magnetized wheel speed sensor. As rust accumulated on the tone ring it would throw debris onto the magnetic sensor and that debris would interfere with the signal, causing the ABS to activate prematurely. GM changed the wheel speed sensor and tone rings in these vehicles.

What causes a wheel bearing hub to go bad?

But nothing is perfect, and when moisture seeps into the hub, it corrodes the tone ring. The result is an uneven WSS signal that confuses the ABS system. The first signs of trouble may be the ABS system kicking in when braking at low speed and/or the ABS warning light coming on.

What are the teeth on an ABS ring?

Old style ABS pickup rings were a ring of metal teeth pressed on to the axle, hub, or rotor. These metal teeth are called the pickup, and each one of the teeth is spaced evenly around the ring.

What to do if ABS wheel speed sensor goes out?

If the ABS wheel speed sensor was faulty, once the new hub/sensor is installed, and you drive the vehicle, the warning lights should go out. To determine what is going on, you can manually erase the trouble codes using an appropriate scan tool and if the warning lights stay off, then the problem is resolved.

What causes an ABS sensor to short out?

Damaged ABS Sensor The ABS wheel sensor monitors the wheel rotation, controlled by its computer. This sensor works as a conjunction with the wheel stator attached to axle brake rotor, bearing hub or CV joint. With time, these sensors may short out as they are subject to vibration or road conditions. 3. Faulty ABS Computer Module

What kind of bearings do I need for my abs sprocket?

Is it safe to assume that the middle one (Part No. 12-3951) might be the total number and types of bearings required for the wheel and sprocket on my 2012 ABS-equipped FLHTK? Is it safe to assume that the middle one (Part No. 12-3951) might be the total number and types of bearings required for the wheel and sprocket on my 2012 ABS-equipped FLHTK?

Where are the wheel bearings on a car?

This is because the front rotors are often behind the front hubs, which means that to change the rotors you have to pull the hubs off the front spindles, at which point the bearings are practically in your hand. So, if you need to do a front brake job, check the wheel bearings.
