Security measures

At performance of repair or service of components of a suspension bracket and a steering 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 it 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 components of a suspension bracket at performance of this or that procedure.
