If you are driving a vehicle for quite a long time then it is possible that few squeaks and sounds have started to originate from the vehicle while driving. This sound can be caused due to various reasons, however, if it is accompanied by vibrations chances are that the bushings of your vehicle are culprit. If this is the problem, it should be taken care of immediately otherwise the squeaks may slowly turn into howling and roaring and you will find it difficult to drive in straight line.

What are rubber bushings in the car

Rubber bushings are tubes of rubber which are cylindrical in shape. They are bonded into inner or outer curves of metal cylinders. Manufactured of avant-garde rubber molds, the rubber used in the bushings are pre-stressed. This helps in providing durability and optimum strength. While installation, they are generally compressed on steel parts. The main function of the rubber bushing is to isolate vibration. For this reason, it is important to keep them in optimal conditions to ensure a correct and comfortable functioning of the car.

Why are rubber bushings important in the car

Rubber bushings are a very small part of the vehicle yet extremely important. The rubber bushing absorbs shock and vibrations and thus insulates other parts of vehicles from constant vibrations and wear and tear due to shock.

Why we need to lubricate rubber bushings

When you buy new vehicle the rubber bushings are already lubricated and hence your drive is smooth. But with each use the rubber bushings face lots of vibrations and shocks which slowly degrade the lubricant or dry it up. This leads to the squeaking sound and the vibration in the vehicle that can be felt by passenger, which makes the journey rather uncomfortable. So, we need to lubricate the bushings to return it back to its former glory.

Best lubricants for rubber bushings

When taking care of the rubber bushings we need to be careful about which lubricant to use. Using a petroleum or oil based lubricant will make matter worse as it will make the rubber swell and slowly disintegrate. For this reason, the two best lubricants for rubber bushings are silicon spray and rubber lube. You will find these type of lubricants in any motor store.

How to lubricate rubber bushings

Getting the lubricant to work properly might be a bit hard. To lubricate the rubber bushing in your car, first you need to remove the bolt holding the component with the bushing. Then, generously spray and lubricate the bushing so it soaks down to it.

If after having generously lubricated the rubber bushings your car still makes a noise, it could be a much serious problem. Maybe the bushing is completely worn out, in this case, you will need to replace the bushings as only lubricating them won't solve the problem.

Really informative article. Kind of a hard read though as there are quite a few grammatical errors. Information was well organized.

Thanks for the comment Chris, we'll add it to our list of article to update!
Very helpful, thank you for the information. Our 2004 Mercury Mountaineer just started squeaking on the right side. I will lubricate all the rubber bushings that I can find and see if the sqeaking stops.
