ABS rings for Volvo S80
The Volvo S80 is a car renowned for its comfort and safety, but even a robust premium vehicle requires regular maintenance of its technical components to maintain its qualities over time. The ABS ring, also known as an ABS reluctor ring, is a critical part of the car's anti-lock braking system and stability control. With us, you will find a wide range of ABS rings specially adapted for the Volvo S80, covering both early models and later iterations. With several specific items in our stock, we cover most requirements for this model series. Choosing the correct component is essential to ensure the vehicle's safety systems can communicate properly with the control unit. A faulty or damaged ring can disable vital functions, negatively affecting both safety and driving pleasure.
What does an ABS ring do on a Volvo S80?
The ABS ring on a Volvo S80 is mounted on the CV joint and works as a toothed tone wheel that rotates in sync with the wheel. A sensor reads the teeth on the ring to measure the wheel's exact rotational speed in real time. This information is continuously transmitted to the car's ABS control unit. If a wheel is about to lock up under heavy braking, the system detects this via the impulses from the ABS ring and regulates brake pressure instantaneously. Without a functioning ring, the system cannot determine the wheel's speed, leading to the anti-lock brakes and often the dynamic stability and traction control (DSTC) failing to operate optimally. It is a simple yet ingenious mechanical component that underpins the vehicle's active safety systems.
Common signs of wear
The most common sign of a broken ABS ring on a Volvo S80 is the ABS light illuminating on the instrument cluster, often accompanied by a warning message stating that brake service is required. The fault is frequently felt as a pulsating brake pedal at low speeds, even during normal braking on completely dry surfaces. This occurs because a cracked ring sends incorrect signals, tricking the system into believing a wheel has locked up when it has not. Because these rings are constantly exposed to the elements and corrosive road salt, corrosion and cracking are the primary causes of failure. A visual inspection can often reveal whether the ring has expanded due to rust underneath or if a tooth has snapped off entirely.
How to choose the correct ABS ring
To choose the correct ABS ring for your Volvo S80, it is essential to check the tooth count on the reluctor ring as well as its exact inner diameter. Volvo used different designs depending on the engine variant and whether the car is front-wheel drive or equipped with all-wheel drive (AWD). The easiest and most reliable way to find the right part is to filter by your car's make, model and engine variant. This will narrow down the components that are technically compatible with your exact car. Also check whether you need to replace the entire constant velocity joint, as the ABS ring is sometimes pre-fitted on an outer CV joint. Measuring the old ring before ordering is always good practice to ensure 100% compatibility, especially on less common engine options.
Related parts to inspect
Be sure to check these exact pages for the same vehicle when working on the ABS ring:
When a drivetrain component shows signs of wear, neighbouring parts on the same car often require inspection too. By checking these exact pages for the Volvo S80, it becomes much easier to determine whether the issue lies solely with the ABS ring or another related driveline component.
This is particularly relevant on models where vibrations, play and unusual noises can shift symptoms across several parts in the same drivetrain. A quick check of related categories minimises the risk of replacing the correct component type while overlooking an adjacent part that affects the same issue.
Replacing a damaged CV boot while renewing the ring can save you significant expense in the future by preventing dirt and moisture from penetrating the joint and ruining the bearing surfaces.

Frequently asked questions about ABS rings for Volvo S80
How do I know if my Volvo S80 needs a new ABS ring?
The most common symptoms are an illuminated ABS warning light, brake system warning messages on the instrument display, or an abnormal pulsating sensation through the brake pedal at low speeds.
Can I replace just the ABS ring or do I have to replace the entire CV joint?
On the Volvo S80, you can usually replace just the ABS ring if the CV joint is otherwise in good condition. This is a cost-effective solution compared to replacing the entire joint.
Why does the ABS ring crack on a Volvo S80?
The most common cause is corrosion developing on the CV joint beneath the ring. As the rust expands, it exerts outward pressure from underneath, which eventually causes the steel ring to snap.
Will a cracked ABS ring cause my car to fail its annual inspection?
Yes, if the ABS warning light is lit or the system is not working correctly, the vehicle will fail its roadworthiness inspection because it is a critical safety component.
How many teeth does an ABS ring for a Volvo S80 have?
The number of teeth varies depending on the model year and engine variant, but 48 or 54 teeth are common. Select your car's model and engine to find the exact match for your vehicle.
Do I need specialist tools to replace an ABS ring?
No, but you will need to release the outer CV joint from the hub carrier. The new ring is then fitted by gently tapping it into place or by gently heating it so it shrinks tightly onto the joint as it cools.
