The 2018 Ram 2500 is equipped with wheel speed sensors, crucial components of the vehicle's Anti-lock Braking System (ABS) and Electronic Stability Control (ESC). These sensors provide real-time data on wheel rotation speed, ensuring optimal performance and safety.

Sensor Locations

The 2018 Ram 2500 has four wheel speed sensors, one for each wheel:

  • Front Wheels: Located behind the wheel hub assembly
  • Rear Wheels: Positioned near the brake backing plate

Front Wheel Sensors

Front wheel speed sensors are typically found:

  • Behind the wheel hub
  • Connected to the steering knuckle
  • Near the brake rotor

To access the front sensors, you may need to:

1. Remove the wheel

2. Detach the brake caliper

3. Remove the brake rotor

Rear Wheel Sensors

Rear wheel speed sensors are usually:

  • Mounted on the axle housing
  • Near the brake backing plate
  • Accessible without removing the axle shaft

Sensor Identification

Wheel speed sensors can be identified by their:

  • Cylindrical shape
  • Magnetic tip
  • Electrical connector

Replacement Considerations

When replacing wheel speed sensors:

  • Use OEM or high-quality aftermarket parts
  • Clean the sensor mounting area thoroughly
  • Avoid damaging the sensor during installation
  • Ensure proper routing of the sensor wire

Common Issues

Wheel speed sensors may fail due to:

  • Physical damage
  • Corrosion
  • Wiring problems
  • Excessive heat exposure

Warning: Faulty wheel speed sensors can trigger ABS and traction control warning lights.

Maintenance Tips

To maintain wheel speed sensors:

  • Regularly inspect for damage or corrosion
  • Keep the sensor area clean
  • Check for loose connections
  • Address warning lights promptly

Remember, proper functioning of wheel speed sensors is critical for your Ram 2500's safety systems.
