Mercedes-Benz S420 Car has excessive body roll Inspection at your home or office.

Common reasons for this to happen:

Excessive body roll can be caused by many different parts of your car not acting properly.

• Loose and worn suspension: The suspension system keeps your car smooth and balanced. It connects all four wheels to the body of the car, and allows the wheels and body to work in tandem. The suspension makes your car one cohesive piece, rather than four separate components. Since the suspension helps hold everything together, it reduces the body roll because it doesn’t allow all of the force to shift to the outside of the vehicle. As the suspension wears out and becomes loose, the drive on the car becomes loose as well, which means that the body roll becomes stronger and more noticeable.

• Shocks need replacing: Like your suspension, your shocks play a key role in helping your car have as smooth a ride as possible. Shocks help limit how much force the body of your car feels, by absorbing a large amount of the impact from the road. While shocks are primarily associated with absorbing bumps and bounces from the road, they also help with body roll. As the force from turning sharply is applied to the vehicle, the shock springs absorb much of the pressure, and limit what you feel inside the car.

• Worn down tires: While your suspension and shocks impact how much body roll your car experiences, tires impact how your car deals with the body roll. Excessive body roll can make it hard to steer, as your car 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 car to handle when facing large amounts of body roll.

• Modifications: Wheels and shock lift kits are two very common modifications for cars, 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 vehicle are hurting the body roll.
