Stabilizer bushes: replacement and selection

When and why it is necessary to replace stabilizer bushes

There are no specific scheduled replacement intervals for these parts. Lifetime limit of the elements depends on driving style and car operation conditions. The bushes are replaced in case of cracks and abrasions. Moreover, loss of parts material elasticity is possible: they harden.

Cracking which leads to integrity loss of the components, as well as changing of material properties of the bushes are natural consequences of their long-time operation. In addition, off-road use of the car also provokes worsening of bushes condition. So, these elements can break down due to wheel impact.

Poor condition of the parts is indicated by light knocking in the suspension. Such sound appears during use of the car on rough road and at turns with small radius on a smooth road surface. Significant body roll can occur at maneuvers, which is accompanied with clicks in the suspension. Moreover, at straightforward driving, worsening of road-holding ability can take place.

Experienced car owners recommend to replace all stabilizer bushes at a time. If necessary, you can buy a special stabilizer repair kit. It can include bolts and washers. In order to perform components replacement you’d better apply to a service station as this is a laborious procedure. A lifting device will be necessary for this work. Moreover, you will need to demount the wheels. The places, where new parts will be installed, should be cleaned from dirt.

How to select stabilizer bushes

These components are made of rubber, polyamide, polyurethane. The rubber bushes absorb vibrations better. At the same time, the polyamide and polyurethane components are more durable.

Operational characteristics of the components greatly depend on a manufacturer. For instance, high-quality stabilizer bushes are produced under LEMFÖRDER, VAICO, Febi Bilstein brands.

When buying the components you need to be guided by main technical characteristics of your car, including the body type. Also you need to consider the design of the stabilizer and parameters of the bush itself: inner and outer diameters, thickness, length and the fastening type. Mounting location is relevant: the right or left side, the front or rear axle.
