The strut bearing / dome bearing for more relaxed driving


The strut support bearing, which is also referred to as strut bearing and dome bearing, is an important vehicle component of the chassis. It is located on both the front and rear axle above the spring on the strut and provides a connection to the body. We offer you qualitative shock absorber mounts in OEM quality from well-known manufacturers such as Sachs, Febi Bilstein, Spidan and co. In the lower part of the page we go into more detail about the functioning of the shock absorber support bearing, the detection of defects on the dome bearing and the replacement of the shock absorber bearing.

function of the strut support bearing in the vehicle

A vehicle usually has a total of four cathedral bearings. Exceptions can be vintage cars, sports cars or off-road vehicles, which sometimes have only two or no bearings at all. First and foremost, the dome bearing is responsible for the precise and smooth steering of the car. While driving, the strut bearings dampen some of the vibrations and noise so that these are not transmitted to the body. Due to the different requirements of the axles, the strut mounts of the front and rear axles are designed differently.

The two strut bearings on the front axle usually have a ball bearing in the middle, which allows the suspension strut to adapt, compensate and rotate according to the steering movements. This results in precise and smooth steering of the car and optimum contact between the tyres and road surface. The rear strut support bearings are of a non-rotating design, as the rear axle of cars is rigid and does not steer. Therefore it does not have a ball bearing and is commonly called a support bearing. In cars with rear-wheel drive or four-wheel drive there are also ball bearings on the rear axle.

In series production vehicles, the dome bearing consists of a rubber-metal element which is easily deformable. This allows the angle of the shock absorber to be changed in relation to the body. In motor sports, strut support bearings made of metal are used.

Why do strut bearings wear out and how can defective strut bearings be detected?

The entire suspension strut, including the dome bearing, is permanently subject to high mechanical stress due to the weight and force of a vehicle. No matter whether it is a kerbstone, cobblestone or pothole - the strut bearing is constantly stressed.

The wear of the strut bearing is therefore strongly dependent on the condition of the road surface. In general, the strut bearing is designed for a service life of 75,000 to 100,000 kilometers. Drivers who frequently drive on "rustic" roads can, however, expect a defective strut bearing even after about 40,000 km or 50,000 km. However, temperature differences, frost and road salt also play a major role in the wear of the dome bearing.

It is therefore advisable to check the strut bearing regularly, regardless of the mileage, to ensure safe driving and prevent further damage to the vehicle. Defective strut bearings lead, among other things, to increased wear and tear on the shock absorbers and tyres.

Common symptoms of a defective cathedral bearing are:

  • Steering is heavier than usual
  • crackling or creaking when steering while standing
  • steering slightly delayed while driving
  • poor cornering of the vehicle
  • A crunching sound is heard when steering the car and during loading and unloading
  • sounds like knocking on uneven roads
  • vibration on the steering wheel

Exchange of the dome bearing - what has to be considered?

Defective strut mounts impair the handling of a vehicle in several ways. Depending on how badly the strut bearing is worn or damaged, the vehicle reacts differently than usual in terms of handling. This can lead to impairments in steering behavior and wheel alignment. Therefore a defect of the strut support bearing should not be underestimated and it should be replaced as soon as possible. In general it is recommended to replace the other axle-side bearing at the same time, if the strut bearing is worn out.

The replacement of a defective strut bearing is a bit tricky, because when dismantling the strut bearing, often many covers have to be removed. Therefore, other typical wear points on the suspension and chassis, such as the axle boots and the shock absorbers should also be checked and replaced if necessary. It should also be noted that after the replacement of the strut bearings, wheel alignment must be carried out by a specialist or a specialist workshop.

The cost of changing the strut support bearings at a workshop depends on the vehicle model and the axle. The price for a set with two strut bearings is between 30 and 80 Euro. The exchange usually takes between two and four hours. If you are not sure which strut bearing is suitable for your vehicle, please contact our customer service! with your 17-digit chassis number.
