Alton Brobst If you own a Subaru, you may have heard of RAB, or you might be wondering what it is. RAB stands for Rear Anti-Roll Bar, and it’s a crucial component of your car’s suspension system.
In this article, we’ll give you an overview of what RAB is, how it works, and how to troubleshoot it if needed.
What is RAB in a Subaru-car context?
The Rear Anti-Roll Bar, or RAB, is a component of a car’s suspension system designed to reduce body roll when turning. Body roll occurs when a car’s weight shifts from one side to the other during a turn. If the car’s suspension system doesn’t properly control the weight transfer, it can cause a loss of traction and reduce stability, especially when turning at high speeds.
The RAB is a steel bar that connects the left and right suspension arms in the rear of the car. The bar transfers forces between the two sides of the suspension, reducing body roll and improving stability when turning.
Benefits of RAB
The primary benefit of the RAB is that it improves handling, especially in curves and turns. By controlling the weight transfer from side to side, it helps keep all four wheels on the ground, increasing traction and improving stability.
In addition to handling benefits, the RAB also helps prevent uneven tire wear, increasing the lifespan of your tires. It also provides a more comfortable and controlled ride, especially when driving on rough roads.
How to Check if Your Subaru Has RAB
If you’re not sure whether your Subaru has RAB, there are several ways to check.
First, check your car’s owner’s manual. It should have information about your car’s suspension system, including whether it has an anti-roll bar.
You can also look under your car and see if there are two metal sway bars connecting the left and right suspension arms in the rear. If you see them, you have the RAB.
Finally, you can take your car to a mechanic or dealership and ask them to check your suspension system.
How to Troubleshoot RAB
While the RAB is a durable component of the suspension system, it can still become damaged or faulty over time. If you notice that your car is leaning too much in turns, or you hear clunking noises coming from the rear of your car, it could be a sign that your RAB needs attention.
If you suspect a problem with your RAB, take your car to a mechanic or dealership for a thorough inspection. They will check the suspension system, including the RAB, and make any necessary repairs or replacements.
FAQs
What is the difference between RAB and a sway bar?
RAB and sway bar are interchangeable terms. RAB stands for Rear Anti-Roll Bar, while the sway bar is located in the front of the car. They both serve the same purpose in reducing body roll and improving stability.
How much does it cost to repair or replace a faulty RAB?
The cost of repairing or replacing a faulty RAB can vary depending on the severity of the issue and the make and model of your car. On average, expect to pay between $100 and $300 for parts and labor.
Can I remove the RAB to improve my car’s performance?
It’s generally not recommended to remove the RAB from your car. Doing so can negatively affect your car’s handling and stability, especially in turns.
Conclusion
If you own a Subaru, it’s important to know what RAB is and how it works. The RAB is a crucial component of your car’s suspension system, providing numerous benefits, including improved handling and stability. If you suspect a problem with your RAB, take your car to a mechanic or dealership for a thorough inspection and any necessary repairs or replacements.
