Technical characteristics

Check of dustproof caps of hinges of an axis

Check of dustproof caps of hinges of an axis: at check of cuffs of hinges of an axis (an arrow on the right) it is necessary to dart a glance also at cuffs of connecting draughts of stabilizers (an arrow at the left).

At the left: check up steering folds on presence of cracks: it is the most convenient to reveal thinnesses by extension of folds (marksman).

On the right: it is necessary to check regularly a condition of dustproof cuffs (marksman) of heads of cross-section steering draughts. Heads of cross-section steering draughts with the torn cuffs should be completely replaced, in warehouses of spare parts of a cuff are not on sale separately.

Hinges of a forward axis between four cross-section levers of an independent suspension bracket and the case of the wheel bearing (the widespread name a rotary fist) are not subject to maintenance service. Steel spherical heads of hinges of an axis take places in greasing of long action and in addition in synthetic covers. As protection against dampness and a dirt dustproof caps from rubber serve. The getting dirt operates on the hinge as an abrasive; dampness causes in due course its rust.

PERFORMANCE ORDER

Completely turn a wheel in one party.
Check up covers of hinges of an axis on the right and at the left on presence of damages.
The dustproof cap cannot be changed separately. It is necessary to change all hinge that makes sense as for certain through a crack the dirt and water have already got.
Therefore the hinge is considered defective still before in it there was appreciable a backlash or scratches.
Replace the hinge.

Council: At check of cuffs of hinges of an axis it is possible to dart simultaneously a control glance at cuffs of hinges of connecting draughts of stabilizers at a forward and back axis (only in quattro). At the expense of their subordinated function they are not the knots providing safety, but at the failed hinges appearing knock at least is burdensome.
