Is Your Swift’s Suspension Noisy? Here’s What’s Wrong & How to Fix It

A noisy suspension in your Maruti Suzuki Swift can be frustrating, especially if it affects your driving comfort and safety. Whether it’s a creaking, knocking, or squeaking sound, it’s essential to diagnose and fix the issue before it leads to bigger problems. In this guide, we’ll help you understand the common reasons behind suspension noise and how you can resolve them.

Common Causes of Noisy Suspension in a Swift

Your Swift’s suspension system is responsible for absorbing shocks and ensuring a smooth ride. However, over time, certain components may wear out or become loose, leading to unwanted noises. Here are some common causes:

1. Worn-out Shock Absorbers – If your shock absorbers are damaged or leaking, they won’t be able to dampen vibrations effectively, causing knocking or rattling sounds.
2. Loose or Damaged Bushings – Suspension bushings help reduce friction between metal components. If they wear out or crack, you may hear squeaks or creaks.
3. Faulty Ball Joints – Ball joints connect the suspension to the wheels. If they dry out or break, they can produce clunking noises, especially when turning.
4. Broken Coil Springs – A broken or weak coil spring can create a banging sound, especially when driving over bumps.
5. Worn-out Stabilizer Links – The stabilizer bar reduces body roll during turns. If its links wear out, you may hear rattling sounds on uneven roads.

How to Diagnose the Suspension Noise

Before jumping to repairs, it’s crucial to diagnose the source of the noise accurately. Here’s how you can do it:

1. Perform a Bounce Test – Push down on each corner of your car. If it bounces excessively, your shock absorbers might be worn out.
2. Listen for the Type of Noise –
   • Creaking – Likely caused by worn-out bushings.
   • Knocking – Could be due to damaged ball joints or suspension links.
   • Squeaking – Usually indicates dry or cracked bushings.
3. Inspect Underneath – Check for oil leaks from the shock absorbers, cracks in the bushings, or rusted suspension components.
4. Drive on Different Surfaces – Listen for changes in noise when driving over bumps, potholes, or rough roads to pinpoint the problem area.

How to Fix a Noisy Suspension in Your Swift

Depending on the diagnosis, you can take the following steps to fix the issue:

1. Replace Worn-out Shock Absorbers

• If the shocks are leaking or ineffective, replace them with OEM or high-quality aftermarket parts.
• Ensure both sides (left and right) are replaced simultaneously for balance.

2. Lubricate or Replace Suspension Bushings

• Use a high-quality rubber-safe lubricant for minor creaks.
• If bushings are cracked, replace them to restore smooth operation.

3. Fix or Replace Ball Joints  

• If they are loose or making knocking sounds, replace them with new ones.
• Apply grease to extend their lifespan and reduce friction.

4. Check and Replace Coil Springs

• If a coil spring is broken, it must be replaced immediately.
• Ensure the new springs match the original specifications.

5. Inspect and Replace Stabilizer Links

• If your stabilizer bar links are worn out, replace them to prevent excessive body roll and noise.

6. Seek Professional Help If Needed

• If you’re unsure about fixing the problem yourself, visit a trusted mechanic for a thorough suspension check.
