Rubber-to-metal Components
Rubber-to-metal components are indispensable construction elements, which not only directly influence driving performance, but also take over other functions. Gearbox and engine bearings connect the transmission and the engine to the chassis. At the same time, they dampen vibrations and eliminate noises such as bucking, engine sounds, reactions to load change, car body drum and transmission noises.

With the chassis, rubber-to-metal components are used to improve steering performance and driving stability. They include strut support mounts, control arm brackets, axle beam and stabilizer brackets, as well as subframe brackets. Furthermore, they create an elastic connection between the individual chassis components.
The fact that rubber-to-metal components are still subject to wear due to mechanical demands and adverse weather conditions, in spite of utmost quality standards, is understandable. The rubber material changes with time. This is why it is sensible to regularly check the parts and to also replace the strut support bearings and damper mounts when replacing struts and dampers, something that will save you money in the long run. When clicking and squeaking noises are heard, we strongly recommend that the respective rubber-to-metal components be checked. Furthermore, the gearbox bearings should also be checked if severe oscillation takes place when changing gears. In general, ZF Services always recommends that all aggregate bearings be changed, even when only one is faulty.
