Hydraulic suspension is used as a ride height and firmness adjustment in your vehicle. It includes parts such as suspension spheres, ride height adjusters and control systems. Suspension spheres are pressurized units that act as a type of pneumatic spring. Often signs of a worn sphere are excessive bouncing and the suspension feels hard especially over bumps. If this is the case then you may need to replace them as they are important for the handling and control of your vehicle. Maintain your vehicle safety by checking these regularly.
