Why Is My Car Suspension Squeaking? (Main Causes Explained)
Before you learn how to stop a squeaky suspension, you need to know what’s causing it. The car suspension system is made up of many parts, all of which can lead to squeaking if it is defective.
If the springs are bad or stretched out, squeaking can occur while the vehicle’s movement isn’t absorbed properly.
Additionally, the shock absorbers are needed to dampen the kinetic energy from the movement. If they become worn, not only might you hear squeaking, but you should also notice more bounce to your drive.
There could also be a lack of lubrication with the bushings that is leading to a squeaking sound. You can find bushings located on the shock absorbers and anti-roll bars. Furthermore, worn out ball joints create a creaking noise, especially when heading around a turn.
You should always take prompt action to complete a squeaky suspension fix at the first sign of trouble. Otherwise, your on-road safety could be compromised.
How To Locate To Exact Source Of The Squeak (Instead Of Guessing)
You can’t learn how to fix a squeaky suspension if you don’t know what part is damaged. Some people bounce the vehicle and try to listen for the defective part, but this is an inaccurate way of diagnosing the problem.
Other people choose to use a stethoscope to find the culprit while bouncing, but this method could crush your fingers, so it’s not advised. Instead, use a simple homemade sound probe by taking a foot-long small-diameter metal rod and slipping a small plastic tube over the end.
You can put this tube up to your ear and the part you think is the problem. While bouncing the vehicle, try to pinpoint the source.
How To Fix A Squeaking Suspension At Home: A Mechanics Guide
How do I stop my suspension from squeaking? With our handy guide, you will learn how to fix squeaky shocks and other suspension parts.
- 1Identify the cause of the squeak. We covered this in the last section if you need more guidance.
Use a floor jack to lift the affected part of the vehicle. Secure the car or truck on jack stands.
- 3Remove the wheel on the affected area.
- 4Locate the defective part.
- 5If you are dealing with a lack of lubrication, use a silicone lubricant to fix the problem.
- 6If you need to replace a part, take it off and put on a new one. When changing shocks and struts, it’s best to replace them in pairs. If you need to fix a squeaky front suspension or you are dealing with a squeaky rear suspension, you would want to replace both of the shocks or struts at the same time.
- 7Put the wheel back on and ensure the lug nuts are properly torqued.
- 8Lower the vehicle back to the ground and take it for a test drive.
Deeper Suspension Issues That May Require A Professional Mechanic
As discussed above, there might be times when the squeaky suspension could be due to something more than a lack of lubricant. If you need to replace the shocks or struts, you may not feel comfortable taking these steps on your own.
Without the proper tools and equipment, changing suspension parts can be overwhelming. Not only that, but you could compromise the safety of the system by not installing the replacements correctly.
If your suspension is squeaking and you are noticing other dangerous symptoms, such as having trouble controlling the vehicle, it’s best to see a professional mechanic for help.
Car Models Prone To A Squeaky Suspension
Because of how the vehicle is made and the parts it uses, there are some models that tend to be squeakier than others.
If you are dealing with a BMW X5 (E70) squeaky suspension, a BMW E60 squeaky rear suspension or a BMW F30 squeaky rear suspension, it could be due to a lack of lubrication.
A Range Rover Sport squeaky suspension might be due to a lubrication problem with the bearings.
Honda Element (Front Suspension)
A front suspension squeak could be due to a cast iron arm on the rubber motor mount assembly that rubs. You might need help from a mechanic to fix this problem.
Nissan Titan (Rear Suspension)
Older Titan models are known for a rear suspension squeak. The company made an add-on kit to get rid of the squeak. It contains a bracket and plastic strips to put around the springs.
If putting lubrication on the sway bar mounts, there could be a loose component on the Ram lift kit you might have installed.
Hyundai Santa Fe
The bushings tend to wear out and create a squeaking sound on some Santa Fe models.
