What is a Rear Hub Assembly?
The rear hub assembly is a pretty important part of your car. And as long as we avoid getting into the crazy details, it’s also pretty simple and easy to understand.
Have you ever had to put on a spare tire, or just taken a wheel off to change the breaks or any other reason?
If the answer is yes, then what you’ve taken the wheel off of is the hub assembly. It is, quite simply, the component that attaches your wheel to the rest of the car. Without a hub assembly, the wheels have nowhere to go. And I’m not sure if you knew this, but a car without wheels isn’t very functional.
Hopefully it goes without saying that your car has four hub assemblies - one for each wheel. And hopefully it goes without saying that the rear hub assemblies are the two hub assemblies for your car’s rear wheels.
While the hub assemblies are attached to the wheels on one side, they’re attached to the suspension on the other side, ensuring that the wheels work with those systems.
As you would expect, hub assemblies are subject to a lot of use and abuse as you drive. But there’s good news: They are extremely durable. It’s not rare for your rear hub assemblies to last the life of your car.
Symptoms of a failing Rear Hub Assembly
Okay, let me give you a quick piece of advice that you should always apply. If your car’s vibrating, then something isn’t right, and that something should be addressed.
If the rear hub assembly begins to wear too much, it may start to transfer some vibrations back into the cabin. You’ll feel that immediately, and don’t take it as a free massage and forget about it.
Things in your car cabin shouldn’t shake. Don’t forget that.
Here’s something that I really hope you don’t need to be told: Your car should not be making weird noises.
Hubs that have an integral wheel bearing may make a growling or humming noise when they’re going out. You also might hear a metal-on-metal grinding noise from the rear wheels. If the rear hub assembly breaks, metal components will scrape against each other as the car drives. It’s about as pleasant of a noise as you would imagine metal-on-metal scraping to be.
Look, I understand that you’re probably not hanging out with your rear hub assemblies on the weekend. But when you get your tires changed, or rotated (which you should be doing, even though you’re not), the technician may notice if the rear hub assembly is starting to go.
A rear hub assembly that is starting to fail may crack or just be visibly worn out.
How urgent is a Rear Hub Assembly replacement?
Well, that entirely depends on how much you would like your car to have a successful steering system. Seriously, is this even a question you need to ask? Get your rear hub assembly replaced as soon as possible to ensure you’re driving safely…and successfully.
