What is an axle tone ring?
A tone ring, also called a reluctor ring, is a notched or toothed ring that’s used in conjunction with a sensor to determine the number of revolutions or speed of revolutions.
What does a rear axle speed sensor do?
The wheel speed sensor is responsible for relaying the wheel speed to the ECU so that it can tell the ABS system how much pressure to safely apply. When the wheel speed sensor is broken or not working as it should, one of the first things that are affected is the ABS system.
What does a tone ring look like?
A tone ring works like a bell. A bell sounds when it is struck with an object causing it to vibrate. The difference between a tone ring and bell is that the vibration is activated by stricking the strings which transfers through the bridge to the head, to the tone ring.
Where are tone rings located?
On most cars, these rings are external, located on the wheel hub assembly or CV joint. However, there are a handful of cars that feature wheel bearing tone rings that are invisible, located inside the sealed wheel bearing.
Does a banjo need a tone ring?
It is generally accepted that the first banjos were constructed without a tone ring. They were built with a round rim made of wood with a skin head (just like a drum head) stretched over the round, wood rim. Clawhammer banjo players in particular, enjoy banjos without a ring mounted to the top of the rim of the banjo.
Where is the wheel speed sensor tone ring?
The wheel speed sensor tone ring is built into the wheel bearing assembly, unlike other wheel speed sensor setups where the tone ring is on the outside of the outer CV joint housing, axle or hub. On the later applications, the WSS tone ring is exposed and very vulnerable to corrosion from road salt and road splash.
How does an ABS sensor work on a trailer?
The ABS sensor and the ABS ring generate an electrical current that is read by the ABS ECU, and this calculates the wheel speed and monitors for traction loss events where the wheel speeds do not match. ABS sensors are a simple coiled wire, and it is easy to test them. What are the symptoms of a bad ABS wheel speed sensor?

What are the purposes of a drive axle assembly?
Purposes of a Drive Axle Assembly •To transmit power from the drive shaft to the wheels •To turn the power flow 90-degrees on RWD cars •To allow the wheels to turn at different speeds while cornering RWD Live Axle Components •Rear axle housing –Holds all other components and attaches to the vehicle’s suspension •Ring and pinion gears
