An important part of the design of a semi-independent vehicle suspension is the support frame, which ensures the connection of the wheels with the car body and other suspension elements. The support frame mounting is a rubber-metal hinge that serves to fix the beam and absorb vibrations and oscillations arising from the contact of the wheels with the road. It consists of two metal bushings and an elastic, elastic insert between them made of rubber or polyurethane.

The usage of support frame mounting

The SWAG brand Mounting, support frame/engine carrier with a polyurethane insert is a strong connecting vibration-isolating suspension part with a long service life. But when driving on roads with poor coverage, the mounting bushing wears out faster, so it may need to be replaced with less mileage. You can determine the need to replace this part by the following signs:

1. creaking or knocking in the rear of the body that occurs while driving;
2. increased vibration while driving;
3. uneven tire wear, with more intense wear of the tread on the sides;
4. instability of the car when cornering;
5. deterioration in directional stability when the car "pulls" to the side when driving in a straight line or braking.
