Search for Anti roll bar rear and front:

Stabilizer bar is a device that refers to the suspension and serves to reduce the side rolls when cornering. Torsion bar, which operates on twist, is designed to create resistance to the roll of car. Torsion is set in the left wheel hub assembly and goes in the direction of its movement to the pin connection. Then it goes in the lateral direction to the opposite side of the car, where it is also set similarly to the first side, but in mirror image. That torsion bar segments that pass in the direction of movement act as levers when the suspension is in the vertical direction.

If there is no roll and two segments are rotated by the same angle, torsion bar is not twisted but rotates at the attachment points of the body as a whole. When there is roll of car left and right segments of the torsion bar are turned at different angles, which allow you to twist torsion and create elastic moment. Due to this resistance to the roll is provided. As for the dependent rear suspensions, they often are absent. Instead of it there are trailing arms attached to the bar with the help of rigid connection. They are able to transmit torque. Thus, the bar together with the trailing arms fulfils torsion bar function.

Regarding the front MacPherson suspension it is worth noting that the torsion lever segments are often used as one of the two lower suspension arms, which transmit longitudinal forces in the direction of movement from the hub to the body. Furthermore, stabilizers can be installed both on two axles or one axle. Usually, it is front axle. It is not difficult to order the stabilizer.

What is necessary to know about stabiliser replacement: lifetime limits, common defects and their signs, tips and recommendation

Useful lifetime of the stabiliser is not specified. Usually it is replaced if the bar itself is deformed or its fasteners become loose.

Typical signs of defects of the front stabiliser bar, as well as the rear one, are rocking and rolling of the car body during cornering and braking, screeching during manoeuvring, knocks in the suspension when driving, worsened road-handling ability.

Diagnostics of the car stabiliser consists of visual inspection. To do so you need to set the car on a servicing pit or a lifting platform. Deformations, dents or cracks, detected during inspection, indicate that the component requires replacement. It is also necessary to make sure that the component ends lie on the same plane, by measuring the distance from each one of them to the floor.

It is recommended to replace the automotive stabiliser at a service station. Before dismounting the part, the front or rear wheels are to be dismounted, depending on the stabiliser being replaced. Then, consequently, all fastening bolts and nuts are unscrewed, the links, the bar and brackets of the component are removed. During the procedure you need to assess condition of various stabiliser parts (rubber bushes, washers, fastening brackets) and replace them if necessary.
