Common Suspension Problems & How To Avoid Them

Common Suspension Problems & How To Avoid Them | German Motorworks

Your car's suspension system is like the backbone of your vehicle, designed to provide a smooth ride and maintain control and stability. This system includes a complex network of components such as springs, shock absorbers, struts, control arms, and sway bars. Let’s dive into the five common suspension problems and tips to prevent them, but first, a quick overview of the main types of suspension systems.

Understanding Different Suspension System Types

Before discussing common problems, let's explore the basic principles of different suspension system types:

  1. Leaf Spring Suspension: Predominantly used in heavy vehicles like trucks, this system uses a series of large steel springs (leaf springs) that flex to absorb motion.
  2. Coil Spring Suspension: The most common type in passenger cars, it uses coil springs to absorb the vehicle's motion, providing a comfortable ride.
  3. Torsion Bar Suspension: Utilizes a torsion bar that twists to provide suspension. Common in some SUVs and trucks, it offers a good balance between ride quality and load-bearing capacity.
  4. Air Suspension: Uses air springs instead of traditional steel springs. It’s adjustable, often found in luxury vehicles and buses for its superior comfort and load-handling ability.
  5. Multi-Link Suspension: A more complex system that typically uses three or more lateral arms and one or more longitudinal arms. It allows for precise control of the wheel motion, ideal for sports and high-performance vehicles.

The 5 Common Suspension Problems


1. Worn or Leaking Shock Absorbers and Struts

One of the most prevalent suspension issues is the wearing out or leaking of shock absorbers and struts. These components are crucial for dampening the impact of road irregularities. Symptoms of this problem include excessive vehicle bouncing, uneven tire wear, and an overall noisy, uncomfortable ride. To prevent such issues, it's essential to regularly inspect your shocks and struts for any signs of damage or leakage. Replacing them at recommended intervals or immediately upon noticing any deterioration is crucial for maintaining a smooth ride.

2. Misaligned Wheels

Misaligned wheels can lead to a host of suspension problems. This misalignment often manifests as uneven tire wear, the vehicle pulling to one side, or an off-centered steering wheel. These issues typically arise after hitting a significant pothole or curb. Routine checks and adjustments of your vehicle’s wheel alignment are vital. An annual alignment check, or one following a severe impact, can significantly extend the life of your tires and improve overall handling.

3. Broken or Worn Springs

The springs in your suspension system play a pivotal role in supporting the vehicle’s weight and absorbing road bumps. When these springs are broken or worn, symptoms like the vehicle sagging, noticeable tire misalignment, or a decrease in handling capability can occur. Inspection of the springs is important, particularly for signs of cracks, rust, or sagging. Timely replacement of compromised springs is essential to maintain the structural integrity and performance of your vehicle's suspension.

4. Worn Out Bushings

Bushings are small rubber or polyurethane components that cushion and reduce friction within the suspension system. Over time, these can wear out, leading to clunking noises, unstable or shaky steering, and uneven tire wear. These symptoms are more common in older vehicles. To avoid these issues, it’s essential to inspect the bushings for wear or damage regularly. Replacing them when necessary helps in maintaining the smooth operation and stability of your vehicle’s suspension.

5. Damaged Control Arms or Ball Joints

The control arms and ball joints are integral to the suspension system, allowing for smooth movement and steering of the wheels. Damage to these components often results in steering wander, uneven tire wear, and clunking noises, especially during turns or when driving over bumps. Regular inspections during routine maintenance checks are essential.
