Power steering liquid Oil for G 002 000 hydrosystems
Forward suspension bracket
Design Independent with MacPherson's racks, screw springs, hydraulic shock-absorbers and the stabilizer of cross-section stability
Convergence of forward wheels 0 ° ± 10' (0 ± 1 mm)
Divergence at turn on 20 °
Models with a normal suspension bracket 1 ° 30'
Models with a sports suspension bracket 1 ° 31'
Disorder of forward wheels – negative (is regulated)
Models with a normal suspension bracket – 0 ° 30 '± 30'
Models with a sports suspension bracket – 0 ° 33 '± 30'
Longitudinal inclination of an axis of turn of forward wheels
Models with a normal suspension bracket 7 ° 40 '± 30'
Models with a sports suspension bracket 7 ° 50 '± 30'
Difference between the parties 0 ° 30'
Maximum angle of rotation of an internal wheel
Models with a normal suspension bracket 38 ° 30'
Models with a sports suspension bracket 38 ° 15'

ATTENTION

Disorder of forward wheels can be changed by a way of shift of a beam of the power unit (work HUNDRED). Thus it is necessary to replace bolts of fastening of a beam of the power unit with the new.


Back suspension bracket
Design Semi-independent, consisting of a cross-section beam and two longitudinal levers. There is a stabilizer of cross-section stability. Springs and gas-filled shock-absorbers are placed separately. All-wheel drive models are equipped with a suspension bracket with dual cross-section levers.
Disorder – negative (is not regulated) – 1 ° 36 '± 20'
The maximum difference between the parties 30'
The convergence (is not regulated) + 0°25 '± 15' (2.77 ± 1.66 mm)
