12.1. Security measures at work
When performing repair or service a component of a suspension bracket and steering you can face a problem of an otvorachivaniye of the rusted bolts and nuts. These bolts and nuts located under the car bottom 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 unscrew by force fixture — you for certain damage it. Apply a large amount of the getting liquid (WD40 type) on the corresponding nut or a bolt and allow it to impregnate a rust. Remove with a wire brush all rust and pollution from visible carving parts of fixture. The sharp blow by the hammer on a nut through a drift can sometimes destroy the rust which is between carving parts of a bolt and a nut. However, striking a nut, you watch that the drift did not come off its surface and did not damage a bolt carving. Turning off the rusted nut or a bolt, use a long neck — it you increase the enclosed effort; however never establish a long neck on a key with 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 used great efforts or damaged its head (its surface), at installation use new (new).As when performing the majority of the procedures described in this Chapter you should lift the car, prepare reliable support. For a poddomkrachivaniye use a cart hydraulic jack. It can be required by you and for posting of a suspension bracket component at implementation of this or that procedure.

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