Security measures at work

At repair or service performance a suspension bracket and steering component you can face a problem of an otvorachivaniye of prirzhavevshy bolts and nuts. These bolts and the nuts located under the bottom of the car, constantly are exposed to external influences. There is nothing surprising that over time they become covered by a rust and partially collapse. Do not try to turn on force fixture — you for certain damage it. Put on the corresponding nut or a bolt a large amount of getting liquid (WD40 type) and allow it to impregnate a rust. With a wire brush remove all rust and pollution from visible carving parts of fixture. The sharp blow a hammer on a nut through a drift can sometimes destroy a rust being between carving parts of a bolt and a nut. However, striking on a nut, watch that the drift did not come off its surface and did not damage a bolt carving. Turning on a prirzhavevshy nut or a bolt, use a long vorotok — it you increase enclosed effort; however never establish a long vorotok on a natural a graggers, as you can not only damage the returnable mechanism of a key, but also be traumatized. If the bolt or a nut does not turn away, try to hold on it slightly. If at a bolt/nut otvorachivaniye you put big efforts or damaged its head (its surface), at installation use new (new).

As at performance of the majority of procedures described in this Chapter you should lift the car, prepare reliable support. For a poddomkrachivaniye use a telezhechny hydraulic jack. It can be demanded to you and for posting of some a suspension bracket component at performance of this or that procedure.

Under no circumstances do not work under the car, leaning only for a jack. At a raising of a back part of the car do not use as a support for the jack lever a cross-section beam.
