Rubber-metal hinges and rubber pillows are subject to replacement at gaps and a unilateral vypuchivaniye of rubber, and also when cutting their face surfaces.

Fig. 4.3. An arrangement of elements of a back suspension bracket on the car: 1 – damping rack of a back suspension bracket; 2 – rubber plug of the lower fastening of a damping rack; 3 – lever of a back suspension bracket; 4 – beam of a back suspension bracket; 5 – the rubber-metal hinge (saylentblok) of fastening of a beam of a back suspension bracket to a body arm

The arrangement of elements of a back suspension bracket on the car is shown in fig. 4.3.

On rubber-metal hinges are not allowed:

– signs of aging, crack;

In case of strong deformation, a local vypuchivaniye and a lead over fittings of the rubber massif replace a support.

3. Examine rubber plugs of the lower hinges of fastening of damping racks.	4. Check rubber-metal hinges (saylentblok) of fastening of a beam of a back suspension bracket to body arms.

5. Examine shock-absorbers (begin to flow liquids and "sweating" are not allowed).	6. Check springs 1 and buffers of compression 2.

7. Check also bearings of naves of back wheels.

Good advice Pay attention to system of production of the fulfilled gases. The foreign knocks published by it often take for knock in a back suspension bracket.
