Forward suspension bracket like McPherson – independent, with the shaking telescopic racks on twisted cylindrical springs, with the stabilizer of cross stability integrated with extensions of the levers of a suspension bracket having a cross arrangement.
The main knot of a suspension bracket is the telescopic rack 9 is put-2141-2904008/09 (right and left), including a damping rack which combines functions of the directing and extinguishing suspension bracket mechanisms. In a rotary fist of a forward suspension bracket, and also in a nave is established with a tightness the two-row radial-stop ball bearing 33 is put. 2141-3103020 with bilateral consolidation which drags on the self-stopped nut.
The moment of an inhaling of a nut of fastening of the drive of forward wheels to a nave of a forward wheel of 180-200 N · m (18–20 kgfs · м).
In use the bearing does not demand adjustment, replacement of lubricant and needlessly is not subject to removal.
At operation inadmissibly even partially to press a nave and a rotary fist from the bearing as it leads to damage of the bearing. Therefore it is necessary to watch an inhaling of a nut of the 38th fastening of a nave.
Vypressovanny bearings for secondary application are unsuitable.
Through damages to rubber covers are the main reason for premature wear of the details working in frictional units. Even at insignificant damages of covers their obligatory replacement is required.
In the presence on the details of a suspension bracket located under a body of the car, zadevaniye traces for road roughnesses it is necessary to check lack on them of damages and cracks.
Rezinoarmirovanny details with traces of attrition of rubber on visible surfaces are also subject to replacement.
During the replacing or repair of the details of a forward suspension bracket influencing installation of forward wheels it is necessary to make control of angles of installation. Failure to follow this requirement can result in premature wear of protectors of tires.
