Wheel hubs and bearings are the master rotational assemblies that allow your tires to spin with minimal friction while supporting the vehicle's entire weight. In your Ram Pickup, these precision components connect your braking system and wheels to the structural suspension. Maintaining these parts helps prevent the dangerous wobble that can compromise passenger safety.

Key Parts to Maintain in Your Wheel Hub Assembly

To properly maintain your wheel hub, pay attention to the following parts:

Hub Flange: The structural plate providing the mounting surface for your rotors and wheel assembly.
Internal Ball Bearings: Precision spheres that carry the vehicle's weight while allowing frictionless rotation.
Magnetic Tone Ring: An integrated digital component that generates pulses for the ABS sensor to monitor wheel speed.
Axle Nut: Secures the assembly to the drive axle and maintains bearing preload.
Outer Dust Seal: A rubber barrier designed to prevent moisture intrusion.

Common Issues With Wheel Hubs to Look Out For

Loud Humming When Turning
Steering Wheel Vibration
ABS Safety Light Illuminated
Rhythmic Thumping at Speed
Uneven Front Tire Wear
