Repair and car operation

The correct installation of forward wheels is extremely important for good controllability of the car and prevention of premature wear of tires. Before starting check of geometry of systems of a steering and a suspension bracket, check pressure in tires, check, whether disks of forward wheels are deformed, and also check, that connections of a steering drive and a suspension bracket were in a good condition, without an excessive free wheeling or wear.

Adjustment of wheels includes four factors:

The corner of disorder of wheels is a corner, on which forward wheels are rejected from a vertical if to look at them in front of the car. Positive disorder of wheels is a corner (in degrees), on which top of a wheel is rejected outside from a vertical. Negative disorder of wheels is a corner (in degrees), on which top of a wheel is rejected inside from a vertical. Adjustment of disorder of wheels is carried out by addition or removal of the washers located between rotary shkvorny of the top lever of a suspension bracket and a body. Washers are established on fixing bolts rotary шкворня.

The longitudinal inclination rotary шкворня is a corner between an axis rotary шкворня and the vertical line if to look sideways the car. Positive the inclination rotary шкворня is when the top of a rotary pin is rejected back. The corner of a longitudinal inclination шкворня is regulated the same as a corner of disorder of wheels except that washers are necessary for adding or cleaning only on a forward or back fixing bolt.

The cross-section inclination rotary шкворня – is also known as a corner of a cross-section inclination шкворня is a corner (if to look in front of the car) between a vertical and the imagined line passing through the top fastening of a rack of a suspension bracket and the spherical hinge of the bottom lever of a suspension bracket or through the centers of plugs rotary шкворня. This corner is not subject to adjustment.

The convergence of wheels is a size on which the distance between internal forward edges of forward wheels (measured at nave height) differs from distance between back internal edges of forward wheels.

As for measurement of small corners of adjustment of a suspension bracket and a steering it is necessary the special optical equipment and exact instrumentations, check and adjustment of a corner of disorder of wheels, a corner of a longitudinal inclination шкворня and a convergence of wheels is necessary for entrusting the experts having the necessary equipment.
