What is a suspension system lubrication?
Your vehicle’s suspension system allows your car to move through rough terrain smoothly while maintaining control. Made up of ball joints, center/drag links, u-joints, control arms, sway bars, and more, your suspension is imperative to your car’s operation. Lubricating these parts on a regular basis helps your car operate at peak performance, and increases its overall lifespan.
When should I perform a suspension system lubrication on my car?
A suspension system lubrication should happen at least twice a year, or by the time provided in your owner’s manual. However, if you experience any of the following common symptoms, you might need to lubricate your suspension system sooner rather than later:
Loud squeaking: Hearing loud squeaking sounds from underneath your car when you hit a bump or pothole may indicate that something in your suspension system isn’t working properly, or that it might need greased. Generally, these sounds can be attributed to parts (such as ball joints) rubbing together to create friction, and left untreated, can result in early wear.
Bumpy riding: If your suspension system isn’t operating properly, then your drive will feel bumpy rather than smooth. This could be due to worn parts, or parts that need to be lubricated for optimal performance.
Groaning while turning: Parts like ball joints help your vehicle to complete turns, and if they need to be attended to, you’ll hear it when you go around a corner. If you hear groaning, it’s best to contact a mechanic or check your suspension once you’re safely at home.
How often should a suspension system be lubricated?
Most manufacturers recommend greasing your suspension twice a year. Regular intervals will help ensure that your suspension components—upper/lower ball joints, rubber bushings, driveshaft—are in top working condition.
The overall time for a suspension lubrication, however, does change with the vehicle’s make and model. Your owner’s manual will be able to give you specific information pertaining to your vehicle.
Can I lubricate the suspension system myself?
Yes, you can grease your own suspension system. Be aware that a suspension system lubrication is much more detailed than working on one specific part and requires a mid-level to intermediate understanding of suspension parts. If you’re unsure of your DIY capabilities, you should take your car to a mechanic for additional assistance.
