Remove and replace the ABS tone ring on a 2022 Rivian EDV 500, which requires removing the wheel hub assembly to access the magnetic encoder ring.

Warnings

Tools required

Parts

• ABS tone ring (magnetic encoder ring) × 1 — Use OEM specification
• Wheel hub assembly (if tone ring is integrated) × 1 — Use OEM specification
• Hub bearing seal × 1 — Use OEM specification
• Axle nut × 1 — Use OEM specification - single use only
• Thread locking compound × 1 — Medium strength

Preparation

1. Park vehicle on level surface and engage parking brake
2. Power down the vehicle completely using the center display power-off sequence
3. Disconnect the 12V auxiliary battery negative terminal and wait 5 minutes for system capacitors to discharge
4. Loosen wheel lug nuts while vehicle is still on the ground
5. Raise vehicle using approved lift points or jack and secure with jack stands rated for minimum 5,000 lbs
6. Remove the wheel on the affected corner
7. Use diagnostic scanner to retrieve and document any ABS fault codes for reference
8. Photograph the sensor position and wiring routing before disassembly

Procedure

1. 1

   Remove ABS wheel speed sensor
   Disconnect the ABS wheel speed sensor electrical connector. Remove the single mounting bolt securing the sensor to the knuckle. Carefully extract the sensor from its bore, wiggling gently if necessary. Inspect the sensor tip for metal debris or damage that may indicate tone ring failure.
2. 2

   Remove brake caliper and rotor
   Remove the brake caliper mounting bolts and hang the caliper from the suspension using a bungee cord or wire - do not let it hang by the brake hose. Remove the caliper bracket bolts. Slide the brake rotor off the hub studs. If stuck, use light taps with a plastic mallet on the rotor face.
3. 3

   Remove axle nut and disconnect suspension
   Have an assistant apply the brakes or use a hub holder tool to prevent rotation. Remove the axle nut using a breaker bar and appropriate socket. This nut is typically high-torque and may require significant force. Disconnect the lower control arm ball joint and tie rod end as needed to allow knuckle removal. On AWD models, support the CV axle to prevent damage.
4. 4

   Remove hub and knuckle assembly
   Remove the strut-to-knuckle bolts if necessary for your specific corner. Carefully pull the knuckle assembly away from the vehicle, sliding it off the CV axle splines. Place the knuckle assembly on a clean workbench. Be careful not to damage the CV boot during removal.
5. 5

   Inspect tone ring configuration
   Examine the hub assembly to determine if the tone ring is a separate component pressed onto the hub, or if it is integrated into the hub bearing assembly. On the Rivian EDV 500, most applications use an integrated magnetic encoder ring that requires full hub replacement. If the tone ring is separate, note its orientation and position before removal.
6. 6

   Remove hub bearing from knuckle (if applicable)
   If replacing only the tone ring on a serviceable hub, use a hydraulic press or bearing press to push the hub assembly out of the knuckle. Support the knuckle properly and press only on the hub center, not the bearing races. Remove the bearing retaining snap ring if present before pressing.
7. 7

   Remove old tone ring
   If the tone ring is separate from the hub bearing, carefully cut or split the old tone ring using a chisel and hammer, or use a bearing separator and press. Work carefully to avoid damaging the hub surface. Clean the hub mounting surface thoroughly with brake cleaner and a wire brush, removing all rust, debris, and old adhesive.
8. 8

   Install new tone ring or hub assembly
   If installing a separate tone ring: Apply a thin coat of thread locking compound or as specified by the manufacturer to the hub surface. Press the new tone ring onto the hub using a bearing press, ensuring it seats fully and squarely against the shoulder. The teeth or magnetic pattern must face outward toward the sensor. If replacing the complete hub assembly: Proceed to install the new hub with integrated tone ring into the knuckle.
9. 9

   Press hub assembly into knuckle
   Apply a light coating of anti-seize to the knuckle bore. Position the new or serviced hub assembly and press it into the knuckle using a hydraulic press. Press only on the outer bearing race, never on the hub center or tone ring. Press until fully seated. Install any snap rings or retaining clips.
10. 10

    Verify tone ring installation
    Use a dial indicator to check hub end play (should typically be less than 0.002 inches). Verify the tone ring rotates smoothly with the hub and has no wobble or runout. If possible, use a multimeter with AC voltage setting or an oscilloscope to verify the tone ring generates a signal by slowly rotating the hub near the sensor mounting location.
11. 11

    Reinstall knuckle assembly
    Guide the knuckle assembly back onto the CV axle splines, being careful not to damage the CV boot. Reconnect the strut-to-knuckle bolts, lower control arm, and tie rod end. Install a new axle nut (single-use component) and torque to specification (consult service manual as no torque specs are available in database - typically 150-200 ft-lbs for this class of vehicle).
12. 12

    Reinstall brake components
    Slide the brake rotor onto the hub. Reinstall the caliper bracket and torque mounting bolts. Reinstall the brake caliper and torque mounting bolts. Pump the brake pedal several times to restore brake pad position before moving the vehicle.
13. 13

    Reinstall ABS sensor
    Clean the sensor bore with brake cleaner. Apply a thin coating of dielectric grease to the sensor O-ring if equipped. Install the ABS wheel speed sensor into the knuckle bore, ensuring proper depth and gap to the tone ring (typically 0.020-0.040 inches - verify with feeler gauge if possible). Torque the sensor mounting bolt. Reconnect the electrical connector and verify it clicks securely.
14. 14

    Reinstall wheel and lower vehicle
    Install the wheel and hand-tighten lug nuts in a star pattern. Lower the vehicle to the ground. Torque the lug nuts to specification in a star pattern (consult service manual - typically 120-140 ft-lbs for this vehicle class).
15. 15

    Reconnect battery and test system
    Reconnect the 12V auxiliary battery negative terminal. Power on the vehicle and verify the ABS warning light follows normal startup sequence (illuminates briefly then extinguishes). Use a diagnostic scanner to check for ABS fault codes. Clear any stored codes if the repair was successful. The vehicle may require a test drive and automatic ABS self-calibration cycle.

Reassembly

1. Torque all fasteners to manufacturer specifications - consult Rivian service manual for specific values not available in this database
2. Verify all electrical connections are secure and properly routed away from moving components and heat sources
3. Ensure CV axle boot is not torn or damaged during reassembly
4. Apply thread locking compound to all critical fasteners as specified
5. Replace all single-use fasteners including the axle nut

Verification

• Start the vehicle and verify the ABS warning light extinguishes after the bulb check
• Use a diagnostic scanner to verify the ABS wheel speed sensor is providing a signal from the repaired corner
• Perform a low-speed test drive (5-10 mph) and verify all four wheel speed sensors show similar readings
• Perform a controlled ABS activation test in a safe area to verify proper system function
• Verify no vibration or noise from the wheel bearing during test drive
• Recheck wheel lug nut torque after 50-100 miles of driving
• If available, use Rivian diagnostic software to perform ABS system recalibration procedure
