4.3.20. Check of a technical condition of details of a back suspension bracket on the car

All checks and works carry out from below the car established on the lift or a viewing ditch (with the hung-out back wheels).

Find out, whether there is no on details of a suspension bracket of cracks or zadevaniye traces about road obstacles or a body, a deformation of levers, bars of the stabilizer, details of a back of a body in places of fastening of knots and suspension bracket details.

Check a condition of rezinometallichesky hinges, rubber pillows, a condition (deposit) of springs of a suspension bracket.

Rezinometallichesky 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–amortizatorny rack of a back suspension bracket; 2–rubber plug of the bottom fastening of an amortizatorny rack; 3–lever of a back suspension bracket; 4–beam of a back suspension bracket; 5–the rezinometallichesky 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 on fig. 4.3.

On rezinometallichesky hinges are not allowed:

– signs of aging, crack;

– unilateral vypuchivaniye of the rubber massif.

Defective details replace.

Check absence of mechanical damages (deformations, cracks, etc.) suspension bracket elements.

1. Remove covers of the top support of amortizatorny racks of a back suspension bracket...	2.... also examine the top support located in salon (on a photo the left shelf of a luggage carrier is for descriptive reasons removed). In case of strong deformation, a local vypuchivaniye and a separation from fittings of the rubber massif replace a support.

3. Examine rubber plugs of the bottom hinges of fastening of amortizatorny racks.	4. Check rezinometallichesky hinges (сайлентблоки) fastenings of a beam of a back suspension bracket to body arms.

5. Examine shock-absorbers (begin to flow liquids and "poteniye" 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 extraneous knocks published by it, often take for knock in a back suspension bracket. Application of non-standard details or break of elements of a suspension bracket of the exhaust silencer can cause strong knock, especially at peregazovka. For check stop the engine, attentively examine release system, check reliability of fastening and an exhaust silencer suspension bracket. Having undertaken for the end of an exhaust pipe, shake the exhaust silencer up-down and here and there — knocks should not be.
