What is a Rear Strut Mount?

Well, they’re mounts. For your rear struts. Oh, I’m sorry, were you looking for a little bit more than that? Okay, fine. Let’s start with the struts. Struts are a part of your car’s suspension, or at least for the cars that have them. They move up and down as your car does, absorbing some of the shock from the road. That keeps the car from dealing with excess stress (which could cause damage), and it keeps you from being subject to excess vibrations. Which is nice. And yes, you take it for granted. Until the system stops working. Okay, onto the mounts. The rear strut mounts are pretty damn important in this operation, okay?. The mounts are what attach the rear struts to the body of the car. One end of the each rear strut mount bolts directly onto the car’s body, and the other end is attached to the strut. That way the strut stays in place. The rear strut mounts do more than just attach the struts to the car’s body. They’re also responsible for some of the shock absorption process that the struts are known for. In between the two ends of the strut mount is a material that provides insulation. As you drive your car over speed bumps, potholes, and other imperfections in the road, the car will bounce up and down. That pulls and pushes on the strut mounts, which allows them to absorb the impact. They also absorb the accompanying noise in the process. As a result of these insulating strut mounts, your car doesn’t bounce as much as it would, or make as much noise. That keeps many components in the car from being damaged further, and it makes for a much nicer ride. Which you’ll realize as soon as a mount fails. Rear strut mounts usually have a very long life, and it’s possible that you’ll never need to replace any of yours. But occasionally they do need to be replaced. And any time the rear struts are replaced, the mounts should be, too.

Symptoms of a failing Rear Strut Mount

Car is vibrating

All right, so you know how I said that rear strut mounts help with shock absorption? Well, when they’re not doing their job, then you end up with a car that isn’t absorbing as much shock as it should. And, as a result, you have some excess vibrations. If one of your car’s rear strut mounts fails, then you’ll notice your car vibrating a bit, and altogether not feeling nearly as stable and comfortable as it usually does.

Clunking noise

Here’s your first lesson about cars: They shouldn’t make any weird noises. If one of your rear strut mounts breaks, the struts may rattle around a bit due to being loose. That will result in a clunking noise when you drive over a bump or a hole in the road.

Uneven tire wear

A damaged rear strut mount will issues to both your suspension and your steering. That, in turn, will cause alignment problems in your car. A car that isn’t properly aligned will put excess stress on some tires, which will lead to abnormal wear and tear. That should be visibly noticeable. Even if you don’t know too much about cars, you should still get in the habit of checking out your tires. Look for low pressure, excessive wear, or bubbles. And look to see if one side is more worn out than the other. If it is, you may have an alignment issue. That might be the result of rear strut mount damage.

How urgent is a Rear Strut Mount replacement?

It’s safe to drive your car short distances even if you need a rear strut mount replaced. But the more you drive on it, the more it will put excess pressure on your suspension, steering system, and tires. That leads to bigger issues, which leads to more costly repairs, which leads to…I mean, you get where I’m going, right?
