Open a collar and a hose clip (shooters) of a protective cover.
Remove a protective cover.
If the cover a long time was damaged, then hit in the dirt mechanism can be a consequence of it. Dirt in a combination to lubricant works as emery paste, destroying the steering mechanism. In this case, and also in the presence of rust traces on a gear lath, it is necessary to take a gear lath to repare (work HUNDRED).
At installation of a protective cover you watch that the small diameter of a cover was included into a groove of steering draft and the cover was not twisted.
