At performance of repair or service of components of a suspension bracket and a steering often there are problems with an otvorachivaniye of the "become attached" bolts and nuts. Located under the car bottom fixture elements constantly are exposed to external influences and there is nothing surprising that over time they begin коррозировать and partially to collapse. Application of a brute force at an otpuskaniye of such "become attached" fixture is interfaced to risk of its damage. For a start moisten an element not giving in to an otvorachivaniye with a small amount of special getting liquid (WD40 type), having allowed the last to impregnate rust layers properly. With a wire brush remove external deposits from available sites of carving surfaces. Sometimes the sharp blow a hammer on a nut through a drift helps to destroy a rust filling gaps between rounds of a carving joint, - try not to allow carving damages as a result of a drift soskakivaniye. Use at an otvorachivaniye of the "become attached" fixture long the vorotka allows to increase considerably an enclosed torque, however it is necessary to remember that use of extension pieces complete with drives of ratchet type is interfaced to risk of failure of the returnable mechanism, not to mention possibility of receiving a trauma.

The fixture damaged in the course of an otpuskaniye is subject to replacement without fail.

As the majority of procedures described in the present Chapter is made on the car lifted over the earth, it is necessary to take care beforehand of options of reliable fixing of a vehicle in the lifted situation, - prepare strong props. For a poddomkrachivaniye of the car use hydraulic jacks of podkatny type, - remember that the onboard jack entering into a standard complete set is intended only for a temporary poddomkrachivaniye of the car at replacement of the failed wheel. The hydraulic jack can be used also for posting of some components of a suspension bracket at performance of this or that procedure.

Under no circumstances do not perform any works under the car withheld in lifted situation only by means of a jack (ов)!
