What problems can a bad hub assembly cause?
Wheel Hub Assembly Failure Symptoms
- A grinding noise or rumbling sound.
- A clicking sound during acceleration.
- Vibrating or loose steering wheel.
- Abnormal side pull during brake application.
- Uneven rotor and brake pad wear.
How do you know if your hub bearing is bad?
10 Symptoms Of A Worn Hub Bearing:
- #1 – Clicking, snapping or popping.
- #2 – Grinding while in motion.
- #3 – Clunking or knocking.
- #4 – Rumbling, humming or growling.
- #5 – Wobble and/or wheel vibrations.
- #6 – Shimmy, shudder, or vibration at constant speeds.
- #7 – Abnormal side pulling when applying brakes.
Why are wheel bearing hubs equipped with wheel speed sensors?
When engineers came up with the idea of putting the wheel speed sensor (WSS) and tone ring inside a sealed wheel bearing hub assembly, it seemed like a great idea. The sealed environment would help protect the sensor and make it less vulnerable to damage or contamination from the outside.
Where are hub assemblies and wheel bearings located?
Why you should maintain hub assemblies and wheel bearings. Located between the brake drums/discs and the drive axle, the hub assembly is mounted to the holding bracket of the chassis on the axle side. On the drum/disc side, the wheel is connected to the hub assembly via bolts. The wheel bearing itself is inside the hub unit.
Why do wheel bearings need to be close to the wheels?
ABS Sensors. Wheel hubs have very intimate relationships with anti-lock braking system (ABS) sensors. That’s because ABS sensors measure wheel speed. To do this accurately, they need to be close to the wheels without being in the way of all of the moving parts.
What does the hub assembly on a car do?
Besides bearings, hub assemblies contain the wheel speed sensor that controls your vehicle’s ABS braking system. The sensor constantly relays to the ABS control system how fast each wheel is turning.
