Pay Attention to Rattling or Knocking

Rattling or knocking sounds, particularly when turning or going over bumps, may suggest issues with your suspension joints or mounts. These sounds should not be ignored, as they can lead to further damage to your suspension system if left unaddressed.

Testing the Suspension

To gain a deeper understanding of your vehicle’s suspension system, you can conduct a few simple tests to assess its performance. These tests can help you identify any weaknesses or areas that require attention. Here are two important suspension tests:

Perform the Push Test

To perform the push test, stand near each corner of your vehicle and push down on it firmly. When you release the pressure, the vehicle should bounce back up smoothly and settle into its normal position. If your vehicle continues to bounce excessively or struggles to return to its original position, it may indicate problems with your shocks or struts.

Conduct the Bounce Test

Another useful test is the bounce test. Stand at a corner of your vehicle and press down on the bumper firmly before releasing. Ideally, the vehicle should bounce once and come to a rest. If it bounces excessively or oscillates several times, it could suggest issues with your suspension system.

Checking the Steering

The steering system is closely connected to the suspension system and plays a crucial role in maintaining a smooth and stable ride. It’s important to inspect and evaluate your vehicle’s steering characteristics to identify any potential issues. Here are a couple of aspects to consider:

Evaluate Steering Responsiveness

Take note of how your steering wheel responds as you make turns or navigate through different road conditions. If you notice any delay, stiffness, or difficulty in steering, it may point to problems with your suspension components or steering system.

Assess Steering Stability

While driving, pay attention to any excessive vibrations or looseness in the steering wheel. A vibrating or wobbly steering wheel could indicate problems with your suspension system, such as worn-out components or misalignment.

Measuring Ride Height

Measuring the ride height of your vehicle is an effective way to ensure that your suspension system is functioning correctly. Ride height refers to the distance between your vehicle’s fender and the ground. By comparing these measurements to the manufacturer’s specifications, you can detect any abnormalities. Here’s how you can measure ride height:

Measure Ground to Fender Height

Using a measuring tape or ruler, measure the vertical distance between the ground and each fender of your vehicle. Take note of these measurements for all four corners.

Compare Measurements with Manufacturer’s Specifications

Refer to your vehicle’s manual or contact the manufacturer to determine the recommended ride height for your specific make and model. Compare the measurements you took earlier with these specifications. If there are significant variations, it may indicate issues with the suspension system.
