9.3.2. Disorder / convergence of wheels
Adjustment of installation of wheels
It is recommended to carry out an inspection of adjustment of wheels after at least 1000-1200 km of a run when springs of a suspension bracket managed to enter a normal operating mode.
It is necessary for check:
– exact adjustment of the measuring equipment;
– that the mass of the car when conducting check equaled only to its own weight with the filled tank and the installed equipment;
– that pressure in tires equaled to standard;
– that the car was located on a plain surface, also before conducting check the car needs to be rocked several times to establish a suspension bracket;
– that there was no excessive free wheeling in the steering mechanism;
– check a suspension bracket for existence of an excessive free wheeling and damages.

Definition / adjustment of a corner of a convergence of back wheels (for cars with the forward drive)
1. If a corner of a convergence of both wheels positive +/+) or negative (-/-), subtract smaller value from bigger and divide on 2.
2. If a corner of a convergence of one wheel positive, and the second negative (+/-), put both values and divide on 2.
