- Be more pronounced during turns.
- Vary in intensity depending on which bearing is affected.
Differentiating Between Bad Alignment and Bad Wheel Bearings
Distinguishing between the sounds produced by bad alignment and failing wheel bearings is crucial to accurate diagnosis. Here are some pointers:
- Wheel Bearings:
- Noise changes in pitch or volume when changing lanes or taking curves.
- Noise may be isolated to one particular wheel area.
- Sometimes accompanied by a wobbly wheel or a hot hubcap.
- Bad Alignment:
- Noise typically consistent regardless of lane changes.
- Often coupled with uneven tire wear.
- May be associated with a crooked steering wheel when driving straight.
Dangers of Ignoring Wheel Bearing Noise
It’s vital not to overlook or ignore the sounds emitted by faulty wheel bearings. Here’s why:
- Safety Hazard: A severely deteriorated wheel bearing can cause the wheel to come off the vehicle, leading to dangerous situations, especially at high speeds.
- Further Damage: Ignoring a faulty wheel bearing can lead to additional wear and tear on related parts, such as the hub, spindle, and brake components.
- Increased Repair Costs: Addressing a problematic wheel bearing early can save significant money. As it deteriorates further, repairs become more complex and expensive.
The Consequences of Driving with Bad Alignment
When a vehicle’s wheels aren’t properly aligned, it doesn’t merely result in an uncomfortable driving experience. Over time, the consequences can be quite severe, impacting both the vehicle’s performance and safety.
Risks of Ignoring Misalignment
- Decreased Fuel Efficiency: Improperly aligned tires can increase rolling resistance, making the engine work harder and thus consuming more fuel.

Understanding Wheel Alignment
Wheel alignment, sometimes referred to as tire alignment, is a critical aspect of car maintenance. To appreciate its significance and the need for periodic checks and adjustments, it’s vital to grasp the basics.
What is Wheel Alignment?
At its core, wheel alignment involves:
- Adjusting Angles: It’s the process of ensuring that the wheels of the vehicle are set to the optimum angles as specified by the vehicle manufacturer.
- Promoting Even Tire Wear: Proper alignment ensures that tires wear down at the same rate, providing maximum lifespan.
- Optimizing Contact with Road: It ensures that the tires make the best contact with the road, improving vehicle safety and performance.
The Three Primary Alignment Angles
There are three main angles that technicians check and adjust during a wheel alignment:
- Camber: This is the inward or outward tilt of the tire when viewed from the front of the vehicle. Improper camber can cause edge-wear on the tires.
- Toe: Imagine looking down at your feet; if you point your toes inward, that’s “toe-in,” and outward is “toe-out.” Similarly, for vehicles, it’s about whether the front of the tires are closer or further apart than the rear.
- Caster: This angle involves the pivot point from the steering mechanism. It affects the steering’s stability and balance.
Why Does Alignment Go Bad?
Several factors can cause bad wheel alignment:
- Normal Wear and Tear: As vehicles age, rubber components start to dry up and metal parts start to wear out, leading to alignment drift.
- Road Conditions: Potholes, bumps, and other road hazards can cause alignment issues.
- Accidents: Even minor fender benders can result in alignment problems.
