ABS rings for Volvo S70 2.3 T5
The Volvo S70 2.3 T5 is a classic performance saloon that demands high-quality components to maintain its driving safety and dynamic qualities. The ABS ring, also called an ABS reluctor ring, is a critical part of the car's braking system that is often overlooked until a problem occurs. On this specific model, the ring is fitted onto the outer CV joint and is subjected daily to harsh conditions including road dirt, moisture and road salt. Over time, the metal can corrode or crack due to rust building up beneath the ring, causing the ABS sensor to lose its signal. We provide parts specially selected to match the requirements of the T5 engine's drivetrain, where precision is vital to avoid unnecessary fault codes and ensure the vehicle's safety systems function exactly as intended from the factory.
What does an ABS ring do on a Volvo S70 2.3 T5?
The primary task of the ABS ring is to act as a toothed pulse generator for the car's ABS wheel speed sensor. As the wheel rotates, the sensor reads the teeth on the ring and sends rotational speed data to the car's electronic control unit. On a Volvo S70 2.3 T5, this system is integrated with both the anti-lock brakes and the stability control. If the ring is damaged or cracked, the control unit can misinterpret the signal. This can cause the ECU to register that a wheel has locked up or is turning at the wrong speed, triggering the ABS system in situations where it is not needed. This affects not only braking performance but also overall drivability and safety in your Volvo, especially under heavy braking or in slippery road conditions where the system must be completely dependable.
Common signs of wear
The most common sign of a failing ABS ring on a Volvo S70 is an illuminated ABS warning light on the dashboard. Often this starts intermittently, such as in damp weather, before turning into a permanent fault. Another clear symptom is feeling vibrations or pulsation through the brake pedal when braking at low speeds on completely dry roads. This happens because a cracked ring produces an uneven signal that tricks the system into thinking the wheel is locking up. If you notice these symptoms, it is important to inspect the ring visually. You can often see that the ring has split across one of the teeth or that the teeth have become so heavily corroded that the sensor can no longer read them correctly.
How to choose the correct ABS ring
Choosing the correct ABS ring for your Volvo S70 2.3 T5 requires attention to detail, as variations can occur depending on the model year and specific chassis numbers. The most critical factors are checking the tooth count on the ring and its inner diameter, as these measurements must match the seat on the outer CV joint precisely to produce a correct signal. By selecting your car's make, model and engine variant, you significantly reduce the risk of ordering the wrong part. We always recommend cleaning the mounting surface on the CV joint thoroughly before pressing the new ring into place, as even tiny flakes of rust trapped underneath can cause it to crack again. Our database is optimised to give you the correct match directly for your specific T5 variant.
Related parts to check
Be sure to check these relevant pages for the same vehicle when working on the ABS ring:
When one drivetrain component shows signs of wear, neighbouring parts on the same car often need to be inspected as well. By checking these matching pages for the Volvo S70 2.3 T5, it is easier to determine whether the issue lies solely with the ABS ring or another related part of the drivetrain.
This is particularly relevant on models where vibrations, play and strange noises can transfer symptoms across multiple driveline components. A quick check of related categories reduces the risk of replacing the right type of part while overlooking an adjacent component that contributes to the same issue.

Frequently asked questions about ABS rings for Volvo S70 2.3 T5
How do I know if the ABS ring is broken on my Volvo S70 2.3 T5?
The most common signs are the ABS warning light illuminating on the dashboard or the brake pedal vibrating during gentle braking on dry roads. A visual inspection will often confirm if the ring has cracked.
Can I replace just the ABS ring, or do I have to replace the complete CV joint?
On the Volvo S70, you can easily replace just the ABS ring, provided the CV joint itself is otherwise in good condition and shows no play or abnormal noises.
Why do ABS rings crack on Volvo models?
This is usually caused by rust developing on the CV joint underneath the ring. The expanding corrosion creates pressure from within that eventually causes the steel ring to crack.
Does a cracked ABS ring affect the vehicle inspection (MOT)?
Yes, if the ABS ring is cracked, the ABS warning light will stay on, leading to an immediate failure and a required re-test at your periodic vehicle inspection.
What tools are needed to fit a new ABS ring?
You will need tools to release the drive shaft from the hub, a wire brush or abrasive wheel to thoroughly clean the seating area, and potentially a heat source to gently warm the ring during fitting.
Is the ABS ring the same on all Volvo S70 models?
No, the tooth count and diameter can vary. It is therefore essential to check by your car's make, model and engine to find the exact replacement part for your 2.3 T5.
