12.1. General information, recommendations and security measures
Forward suspension bracket
Forward suspension bracket of Nissan Micra K12 cars independent, with Mac-Fersona racks, cross-section levers and the stabilizer of cross-section stability. Elements of a forward suspension bracket the beam connected to a body by bolts is bearing. On a beam both cross-section levers which are in turn connected by boats to rotary fists are fixed. Suspension bracket racks also fasten on rotary fists. The nave and the wheel bearing are not subject to adjustment and repair.
Back suspension bracket
Back suspension bracket dependent, with shock-absorbers separately established on a beam and screw springs.
The steering mechanism with drafts
Steering reechny, with the electroamplifier (EPAS). In a steering wheel the forward safety cushion of the driver is established. The steering mechanism has no люфтов and does not demand service, except check of a condition of its boots, and also boots of tips of steering drafts.
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 over time are exposed to corrosion and partially 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, having allowed it it is good to impregnate a rust layer. 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 otdavaniye 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, and also with 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 its reliable fixing 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.
Work under the car withheld in lifted situation only by means of jacks is not allowed!
Carrying out welding and rikhtovka of bearing elements of a suspension bracket, and also elements of a steering is not allowed. Самоконтрящиеся and the fixture damaged by corrosion in the course of repair it is necessary to replace nuts.
