Introduction
The rear wheel hub assembly is a crucial component that supports the vehicle's wheels and facilitates smooth rotation. Identifying a faulty hub assembly promptly is essential to maintaining vehicle safety and performance. This article examines the indicators of a failing rear wheel hub assembly and how to diagnose its condition effectively.
Symptoms of a Bad Rear Wheel Hub Assembly
Unusual Noises
Listen for growling or humming noises emanating from the wheel area, especially while driving at moderate speeds. These noises may become louder during turns.
Wheel Play
Lift the vehicle and manually check for excessive play by shaking each wheel. Increased movement might indicate a worn hub assembly.
Vibrations
Feel for any unusual vibrations in the steering wheel or the floorboard, primarily when accelerating or turning. Such vibrations often suggest an issue with the hub bearing.
ABS System Triggers
A malfunctioning wheel hub assembly can cause the Anti-lock Braking System (ABS) light to illuminate on the dashboard due to sensor errors.
Diagnosis Procedures
Visual Inspection
Inspect the hub assembly for visible signs of wear, such as corrosion or damage to the seals. Leaking grease is also a critical indicator of a failing hub.
Use of Diagnostic Tools
- Wheel Alignment Gauge: Misalignment could be a sign of a worn hub assembly influencing the wheel's position.
- Noise Detection Tracer: Pinpoint the exact location of troublesome noises using specialized tools, which can confirm a problematic hub.
Measurement Parameters
- Wheel Lateral Runout: Measure lateral movement not exceeding 0.002 inches (0.05 mm) to ensure hub integrity.
- Torque Specifications: Confirm bolts are tightened to manufacturer specifications, typically ranging from 85 to 115 foot-pounds for rear wheel drives.
