Understanding Car Suspension and Ride Height After Servicing

When you visit a mechanic for routine servicing, you might notice that your car seems to have increased in ride height. What could have caused this? Can a car jack keep a car lifted even when removed? Let's delve into the mechanics of car suspension and ride height to understand these phenomena better.

Can a Car Jack Keep a Car Lifted?

Often, a concern among car owners is whether a jack can keep a car lifted once the jack is removed. The short answer is no; a car jack cannot keep a vehicle elevated after it is removed. A car jack acts as a temporary support while the undercarriage is accessed for repairs. Once the jack is removed, the car resumes its normal ride height, determined by its suspension system.

After being raised and lowered, the car's suspension needs to settle into its natural position. Tires' friction on the ground prevents the suspension from settling correctly, leading to a temporary increase in ride height. This can be more pronounced if the vehicle sits on moveable plates or turntables during wheel alignments, allowing the suspension to settle with a few bounces rather than being driven immediately.

Factors Affecting Car Ride Height

The increased ride height after servicing a car can be due to various factors, including:

Ride Height Adjustment: Mechanics might have adjusted the suspension, replacing parts such as shocks, springs, or control arm bushings. Uneven Tire Pressure: Incorrect tire pressure can lead to an elevated ride height. Foreign Objects or Fluid Leaks: Introducing foreign objects or fluid leaks into the suspension can cause temporary height changes. Incorrect Installation: A misinstallation of parts or incorrect repair procedures can lead to ride height issues.

Debunking Common Myths

The idea that a car jack can keep a car lifted indefinitely is a common myth. However, the suspension can be affected by several elements. For instance, if a mechanic adjusted the suspension or installed new parts, the ride height could indeed increase. The ride height returns to normal as the suspension settles, which typically happens within a short driving distance.

Ways to Check and Address Ride Height Issues

Inspecting the car's suspension can help identify the source of ride height issues:

Check Tire Pressure: Ensure all tires are inflated to the recommended pressure levels. Inspect the Suspension: Look for any damaged or missing parts, and ensure that all components are properly aligned. Check for Foreign Objects: Remove any foreign objects that might have entered the suspension system. Verify Correct Installation: Ensure that all parts were installed correctly and that repairs were performed according to the manufacturer's guidelines.

For optimal peace of mind, consider having your car's suspension inspected by a professional. Reliable car insurance, such as Insurance Panda, can also provide you with coverage and assurance if something goes wrong on the road.

Key Takeaway: A car jack cannot keep a car lifted indefinitely. If your car's ride height has increased, it's likely due to some work done on the suspension or other mechanical adjustments.

Conclusion

Understanding the mechanics of car suspension and ride height can help you address issues that may arise after servicing. Regular maintenance and professional inspections can ensure that your car remains in good condition, leading to safer and smoother driving experiences.
