Understanding Strut Mount Bearings

What is a strut mount bearing?

A strut mount bearing connects the strut with the body of the suspension, which is a pivotal part of both the performance and safety of your vehicle. The front axle strut bearings allow for the strut to turn when you steer, which maintains smoothness and sense of precision to your drive. Not only this, but strut mounts also cut down on the noise created between the suspension and the body, making for a calmer and quieter drive. They are designed to last from the day the vehicle leaves the factory gates until the day the vehicle retires. Things such as weight, wear, changes in temperature, changes in humidity, salt, frost, and more can shorten the lifespan of the strut.
What are the symptoms of a bad strut mount?

Due to the importance of the strut mount bearing on your vehicle and the safety of those travelling within it, it is pivotal that you know how to spot the signs of a defective part. If you drive over a bump in the road or pothole and hear a loud bang, this may be an indication to have the strut mount checked. Similarly, if the vehicle’s steering starts to feel heavier than normal, or even jerks to one side, it may be a result of a defective strut. If this is the case, have one person stand outside the parked car while you start the engine and turn the steering wheel. If there is a squeak or creak emitting from the car, one or more of your strut mount bearings may be broken.

How much does it cost to replace a strut mount?

To replace Headlights of struts on your vehicle, it can cost you as much as $900. Strut assembly costs can range from $150 to $300, which sets you back up to $600 on the strut parts alone. However, while this is a frustrating cost to pay, knowingly leaving your strut mount bearings defective can put you and others in danger, as well as run the risk of damaging other parts of your vehicle.

Can you drive with a broken strut mount?

How do I know if my strut bearings are bad? You should never drive your vehicle if you know that the strut mount bearings are defective. Not only is it dangerous to yourself, those in your vehicle, and those you meet on the road, but it can also cause further damage to other parts of the suspension. More damage equals a greater repair cost for you. Defective strut mount bearings can result in uneven tire wear, increased shock absorber wearing, a drop in steering response and control, problems with tracking, and increased stopping distances.
How do you grease a strut mount?

Squeaking noises from your strut mount bearings may require the part to be greased, so it is important to know exactly how to do this. Use your jack to raise your vehicle safely, supporting it with your stands. If you do not have clear free access to the strut, you may have to remove the wheel. Take a can of aerosol and spray it against the strut bearings, the turn plate, and the bushings to lubricate them. Then fill a syringe with grease and inject it onto all three parts again. If you were unable to reach certain parts, take a long-nozzle oil can and make sure to grease them too. You can then replace the wheel, safely lower the car, and check for squeaks and creaks again.
