Mastering the ABCs of Car Handling: Alignment, Brakes & Chassis

Whether you use your car for daily transportation or simply for leisure, it's important not to overlook issues like squeaking brakes or a bumpy ride. Understanding the basics of your car's features and systems, as well as signs of suspension or brake problems, are crucial for every driver. By familiarizing yourself with these aspects, you can gain confidence and ensure your safety while on the road.


What You Need to Know About Your Car's Handling

Clunking noises, shaking, or excessive vibrations can be worrisome for any car owner. However, having a solid understanding of your vehicle's steering, suspension, and brake systems can provide you with valuable information to identify and address potential issues. While there are various symptoms related to poor handling, being aware of your car's existing or potential problems will enable you to stay ahead of more serious complications.


Wear and Tear on the Suspension System

The suspension system in your vehicle plays a vital role in absorbing road shocks, adapting to uneven terrains, and providing a comfortable ride. Among the crucial components of the suspension system are shocks and struts, which help minimize impact, vibrations, and braking distance while enhancing ride comfort. Additionally, the suspension system ensures constant tire contact with the road, maintaining traction in different driving conditions. Over time, the moving parts of the suspension system can experience damage, looseness, or failure due to factors such as regular use, heat, and corrosion. Neglecting these issues can result in discomfort while driving, safety concerns, or even severe damage. Faulty shocks, struts, ball joints, bushings, or suspension mounts can noticeably affect your car's handling and may cause tire and steering component damage if left unaddressed.


Signs of Failing Suspension Components:

  • Excessive bouncing or loss of stability
  • Pulling to one side while driving
  • Swaying or rolling during turns
  • Front end dipping or nose-diving when braking
  • Knocking or clunking sounds from wheels or underneath the vehicle
  • Bottoming out on bumps or uneven surfaces
  • Wheel alignment problems or diminished steering control
  • Rear end squatting during acceleration
  • Fluid or gas leaks from the shock absorber or grease leakage from suspension parts


Strut and Wheel Bearings: Ensuring a Smooth and Safe Ride

Understanding the bearings in your car's suspension system, their significance, and the signs of potential failure is essential when it comes to your vehicle's ride quality. Depending on your vehicle's design, it may have shock or strut bearings that secure the shock absorbers and struts. Additionally, nearly every vehicle on the road incorporates wheel bearings or hub bearings that enable smooth wheel rotation. Over time, bearings can wear out or sustain damage due to factors like collisions, inadequate lubrication, corrosion, or driving habits. Neglecting to service or replace a faulty bearing can have serious implications, affecting both the comfort and safety of your vehicle. Ignored issues may lead to metal-on-metal contact and suspension damage.


Signs of Worn or Damaged Wheel or Strut Bearings:

  • Clunking, grinding, or knocking noises while driving or going over bumps
  • Excessive vibration or wobbling in the steering wheel or wheels
  • Unusual sounds originating from the steering or suspension systems
  • Rapid wear of shock absorbers
  • Uneven tire wear
  • Steering wheel failing to turn back or return to the center position when released


Steering and Alignment Concerns

The steering system in your car facilitates wheel movement and is controlled by the steering wheel and steering column. When you turn the steering wheel, various components, such as the steering column, tie rods, rack and pinion unit, and more, work together to translate that change in direction to the wheels, ensuring responsive and accurate steering control. However, continuous use, heat, and pressure can cause steering components to fail, corrode, loosen, or separate. It is crucial to inspect and address any steering issues or failures promptly to ensure your safety and the safety of others on the road.

  • Diminished handling or imprecise steering
  • Pulling to one side or wandering
  • Vibrations or looseness felt in the steering wheel
  • Rapid or uneven tire wear


Alignment's Impact on Suspension:

Proper alignment is crucial for a well-functioning suspension system. Aligning your vehicle ensures that your wheels remain parallel and your suspension geometry stays within specifications. Regular alignment maintenance is recommended, typically once every year or two. However, more frequent alignments may be necessary depending on your driving habits. If your car pulls to one side while driving, or if you've had an impact with a curb or been involved in a collision, it's advisable to have your alignment inspected and adjusted as needed. Misalignment can lead to unusual tire wear, decreased fuel efficiency, and potential damage to suspension, wheel end, and steering components. If you experience any of the following symptoms, it's crucial to have your car professionally inspected and serviced to prevent further issues:

  • Vehicle pulling to one side
  • Uneven or rapid tire wear
  • Excessive bumpiness or vibration while driving
  • Crooked steering wheel


Brake Problems:

Your vehicle's braking system is paramount to your safety on the road, providing responsive and smooth stops to avoid collisions. However, with constant demands, high temperatures, and components prone to wear and corrosion, the braking system may require maintenance or repairs throughout your vehicle's lifespan. Components like brake rotors, pads, calipers, the master cylinder, and brake fluid work together to deliver efficient braking performance. Leaks, damage, corrosion, or wear over time can compromise braking effectiveness, putting you and others at risk. If you observe any of the following signs, it's crucial to have your brakes inspected for damaged components that can affect their performance:

  • Vibrations in the steering wheel during braking
  • Vehicle pulling to one side when braking
  • Illuminated brake warning light
  • Grinding or squealing noises while braking
  • Softer or harder brake pedal than usual
  • Longer stopping distance or complete lack of brake pressure

Prompt professional inspection and service are essential to address these issues and ensure the safety and performance of your vehicle.
