12.1. General information, recommendations and security measures
Forward suspension bracket of the Saab 9-5 cars independent, with Mac-Ferson's racks, cross levers and the stabilizer of cross stability. Levers and the stabilizer fasten to a forward stretcher. Naves rotate in the bearings installed in rotary fists. On early models stupichny bearings can be replaced separately, and on late models the nave and its bearing represent the non-demountable block fixed on a rotary fist by bolts.

Back suspension bracket independent, with racks, longitudinal levers, the lower and top cross drafts and the stabilizer of cross stability. Cross drafts and the stabilizer fasten to a back stretcher. Naves of back wheels with two-row bearings represent non-demountable knot and fasten to longitudinal levers hairpins and nuts.

Steering is rack, with the hydraulic booster (GUR). The pump GUR is given from a bent shaft by a belt of the drive of auxiliary units. The steering column developing that increases safety of the driver at accident. GUR liquid moves the pump to the control valve which, depending on the direction of rotation of a steering wheel, directs liquid to one of the parties of the executive cylinder. In the cylinder liquid affects the piston, giving additional effort to the steering mechanism.

When performing repair or service of components of a suspension bracket and steering often there are problems with an otvorachivaniye of the "stuck" bolts and nuts. Fixture elements located under the car bottom constantly are exposed to external influences and over time are exposed to corrosion and partially collapse. Use of brute force at an otpuskaniye of such "stuck" fixture is accompanied by risk of its damage. For a start moisten the element which is not giving in to an otvorachivaniye with a small amount of the special getting liquid (WD40 type), having allowed it it is good to impregnate a rust layer. Remove with a wire brush external deposits from available sites of carving surfaces. Sometimes the sharp blow by the hammer on a nut through a drift helps to destroy the rust filling gaps between rounds of a carving joint, - try not to allow damages of a carving as a result of a drift soskakivaniye. Use at an otvorachivaniye of the "stuck" fixture of a long neck allows to increase considerably the enclosed torque, however it is necessary to remember that use of extenders complete with drives of ratchet type is accompanied by risk of failure of the returnable mechanism, and also by a possibility of getting injured. Fixture damaged in the course of an otpuskaniye is subject to replacement without fail.
As the majority of the procedures described in the present Chapter is made on the car lifted above the ground, 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, – you remember that the onboard jack which is included in a basic equipment is intended only for a temporary poddomkrachivaniye of the car when replacing of the failed wheel. The hydraulic jack can be used also for posting of some components of a suspension bracket at implementation of this or that procedure.
