Why Test Shocks?
Before we dive into the process of testing shocks, it’s essential to understand why it’s crucial to test them. Worn-out shocks can lead to a bumpy and uncomfortable ride, reduced handling, and increased stopping distance. In extreme cases, it can even cause the vehicle to lose control, putting the driver and passengers in danger. Testing shocks can help identify any issues before they become severe, allowing you to make the necessary repairs or replacements.
Tools You’ll Need
Before you start testing shocks, you’ll need a few tools. Fortunately, you won’t require any specialized or expensive equipment. Here’s what you’ll need:
- Jack and jack stands
- Wrenches
- Measuring tape
- Pen and paper
Step-by-Step Guide to Testing Shocks by Hand
Now that you have everything you need let’s start testing shocks by hand.
Step 1: Park Your Vehicle on Level Ground
Park your vehicle on a level surface and engage the parking brake. This will ensure that the vehicle doesn’t move while you’re testing the shocks.
Step 2: Lift the Vehicle
Use a jack to lift the vehicle off the ground and secure it on jack stands. Make sure the vehicle is stable and won’t fall off the jack stands.
Step 3: Check the Shocks for Visible Damage
Before testing the shocks, inspect them for any visible damage, such as leaks, cracks, or dents. If you notice any damage, it’s best to replace the shocks before testing them.
Step 4: Test the Front Shocks
To test the front shocks, push down on the front of the vehicle with your body weight and release. The vehicle should rebound once and then settle. If it continues to bounce or doesn’t rebound at all, the shocks are worn out and need replacement.
Step 5: Test the Rear Shocks
To test the rear shocks, repeat the same process as the front shocks. Push down on the rear of the vehicle with your body weight and release. Again, the vehicle should rebound once and then settle. If it continues to bounce or doesn’t rebound at all, the shocks are worn out and need replacement.
Step 6: Measure the Distance
Measure the distance between the vehicle’s body and the axle or control arm. With the vehicle on the ground, measure the distance, and then repeat the measurement with the vehicle lifted. The difference between the two measurements should be no more than 25mm. If it’s more than that, it’s a sign that the shocks are worn out and need replacement.
Step 7: Test the Shocks on Rough Terrain
Testing shocks on rough terrain can help you identify any issues that you might have missed during the previous steps. Take the vehicle for a short drive on a bumpy road or over speed bumps. If the vehicle bounces excessively or feels unstable, the shocks are worn out and need replacement.
FAQs
Q: How often should I test my shocks by hand?
It’s recommended to test your shocks by hand every 12,000 miles or once a year, whichever comes first.
Q: How do I know if my shocks need replacement?
If you notice any visible damage, such as leaks, cracks, or dents, it’s a sign that your shocks need replacement. Additionally, if your vehicle bounces excessively or feels unstable on rough terrain, it’s an indication that the shocks are worn out.
Q: Can I test shocks by hand if I don’t have a jack?
No, it’s not safe to test shocks by hand without lifting the vehicle off the ground. Using a jack is essential to ensure your safety while testing shocks.
Conclusion
Testing shocks by hand is a simple process that can help you identify any issues before they become severe. By following the steps outlined in this article, you can ensure that your vehicle’s suspension system is in good working condition. Remember to test your shocks regularly and replace them as needed to ensure a smooth and comfortable ride.
