Every vehicle has body roll; the law of physics makes it impossible for vehicles not to have at least a little body roll. But when your vehicle has excessive body roll, it’s not only more difficult to drive, but a little unnerving too. Excessive body roll is a scary feeling, and slows your vehicle’s ability to turn. It’s an issue that you should get handled in a timely manner.
How this system functions:
When you make a sharp or fast turn in your car, all of the force is pushing away from the turn. If you’re turning left, the force on your car is pushing it to the right. This makes the body – and therefore the weight – of your vehicle to be on the outside of the turn. If you then turn in the other direction, the force and weight have to shift to the other side of the car. While body roll exists in every vehicle, many systems in your car, such as the shocks, suspension, and your tires, help reduce the amount of body roll, and the impact that it has on the driver.
Common causes of car body roll:
Excessive body roll can be brought about by many different parts of your car not acting properly.
- Loose and worn suspension: The suspension system keeps your vehicle smooth and balanced. It links all four wheels to the body of the vehicle, and lets the wheels and body to work in tandem. The suspension makes your vehicle one cohesive piece, rather than four separate parts. Since the suspension helps hold everything together, it reduces the body roll because it doesn’t let all of the force to shift to the outside of the vehicle. As the suspension wears out and becomes loose, the drive on the vehicle becomes loose as well, which means that the body roll becomes stronger and more observable.
- Shocks requires replaciement: Like your suspension, your shocks play a key role in helping your vehicle have as smooth a ride as possible. Shocks help limit how much force the body of your vehicle feels, by absorbing a large amount of the impact from the road. While shocks are primarily linked with absorbing bumps and bounces from the road, they also help with body roll. As the force from turning sharply is applied to the car, the shock springs absorb much of the pressure, and limit what you feel inside the vehicle.
- Worn down tires: While your suspension and shocks impact how much body roll your vehicle experiences, tires impact how your car deals with the body roll. Excessive body roll can make it hard to steer, as your vehicle has a hard time gaining traction on the road and straightening itself out. If your tires are worn down, and lacking tread, then this impact is magnified. Worn down tires have a very hard time gripping the road, and will make it difficult for your vehicle to handle when facing large amounts of body roll.
- Modifications: Wheels and shock lift kits are two very common modifications for vehicles, but both of them can have adverse impacts on how your car handles body roll. A mechanic will be able to tell you if the modifications made to your car are hurting the body roll.
- How car body roll repairs is done:
A mechanic will thoroughly check your vehicle to discover where the excessive body roll is coming from. They may drive your vehicle, to help determine whether the problem is originating in the suspension, shocks, or tires. Most car parts that cause excessive body roll will need replacement, rather than repair.
How important is car body roll repairs?
Excessive body roll can make driving scary, and it also limits how quickly your vehicle responds to you turning the wheel. But the most dangerous part of excessive body roll is that the primary areas where it starts from (the suspension, shocks, and tires), can cause much worse damage if their problems are ignored. Whenever you notice excessive body roll, you should schedule an inspection as soon as possible.
