Extended Product Information

FAQs

How do I know if this ring fits my car?

Check your vehicle's service manual for the part number or compare the dimensions (165mm OD, 124mm ID) and tooth count (80) against your existing part.

Do I need special tools to install this?

Yes, a hydraulic press or a specialized hub bearing tool is often required to ensure the ring is pressed on evenly without damage.

Should I replace the ABS sensor when I replace the ring?

While not strictly required, it is good practice to inspect the sensor for damage or wiring issues while the assembly is apart.

Can this be installed on the front axle?

No, this specific part is designed for the rear axle assembly; check the catalog for front-specific applications.

What happens if the ring is installed slightly crooked?

A crooked ring will cause the sensor gap to fluctuate, resulting in incorrect speed data and likely triggering an ABS fault light.

Troubleshooting

ABS light remains on after installation

Verify the ring is seated fully flush and check that the distance (gap) between the sensor and the teeth is within the manufacturer's specified tolerance.

Erratic ABS behavior at low speeds

Check the ring for any physical damage or bent teeth that might have occurred during the installation process.

Sensor cannot read signal

Ensure the wheel speed sensor itself is clean and free of metal filings that may have been attracted by the magnetic components of the hub.

Pros and Cons

Pros

  • Meets or exceeds high manufacturing quality standards
  • Essential for restoring proper ABS functionality
  • Precise tooth count ensures accurate sensor data
  • Reliable fitment for rear axle assemblies

Cons

  • Requires significant disassembly of the hub/axle for access
  • May require professional tools to seat the ring properly
  • Compatibility limited to specific vehicle make and model configurations

Setup, Compatibility & Care

Before installation, ensure your vehicle requires an 80-tooth ring with the specified 165mm/124mm diameters. The installation process typically involves removing the brake disc and the wheel hub assembly. Ensure the surface of the hub is thoroughly cleaned of all rust and debris to allow the ring to seat flush; failure to do so may result in run-out, which causes inaccurate speed readings. Apply a thin layer of anti-seize or recommended lubricant if specified by the vehicle manual to prevent future corrosion. We recommend using a specialized press tool or a drift to seat the ring evenly to avoid bending or cracking the component during installation.
