Check of a condition of components of a suspension bracket and steering

Components of a steering drive and suspension bracket should be checked regularly. The worn out or damaged components of a suspension bracket and a steering drive can serve as the reason of excessive and dangerous deterioration of tyres, deterioration of running characteristics and controllability the car and to increase of the expense of fuel. For more detailed information on components of a suspension bracket and steering system address to the Head the Suspension bracket and a steering.

Rack/shock-absorber check

1 Park the car on an equal platform, switch off the engine and cock a lay brake. Check up pressure in tyres.
2 Press one of car corners, then release it, paying attention to body movement. It should cease to shake and rise in a starting position after one or two качков.
3 If the car continues to be shaken or has not come back in a starting position the possible reason of it is the worn out either weakened rack of a suspension bracket or the shock-absorber.
4 Repeat the procedure described above for each of three remained corners of the car.
5 Poddomkratte the car and reliably establish it on support.
6 Examine racks/shock-absorbers on presence of signs of leak of a hydraulic liquid. The easy film of a liquid is not at the bottom for anxiety. In case of leak detection make sure that the liquid follows from a rack/shock-absorber, instead of whence still. If it nevertheless leak from a rack/shock-absorber, replace racks or shock-absorbers in steam on one bridge (or all four).
7 Check up reliability of installation and integrity of racks/shock-absorbers. Check up the top support of racks on presence of damages and deterioration signs. In case of detection of those replace racks or shock-absorbers.
8 In case of need replacements of racks or shock-absorbers address for instructions to the Head Brake system. Always replace both components on one bridge, otherwise there can be a threat of safety of the car. If it is possible, try to replace all four components in the complete set.

Check of a condition of system of a steering and suspension bracket

9 Examine components of system of a steering on presence of damages and deformations. Search for signs of leak of the liquid, the damaged linings, protective covers and штуцерные connections.
10 Clear the bottom end of a rotary fist. Ask the assistant to grasp a bottom edge of a wheel and to shake it, and at this time observe of movement of the spherical support connecting a rotary fist with the lever. Examine protective covers of spherical support on presence of ruptures. If you find out люфт either it is necessary to replace the torn or proceeding protective covers, a spherical support (support).
11 Grasp each of forward wheels for forward and back edges and try to turn its first line inside, and back outside to check up presence люфта in a steering drive. If it is found out люфт, check up, whether ослабли fastenings of the steering mechanism and hinges of steering draughts. If ослабли fastenings, tighten them. If ослабли steering draughts the worn out hinges (check up at first reliability of a tightening of nuts) can be the reason. The additional information on system of a steering and a suspension bracket can be found in the Head Brake system.

Check люфта a steering

12 Establish a steering wheel in average position.

13 Move a steering wheel here and there, observing thus of forward wheels. The steering wheel can have люфт no more than 25 mm.

14 At большем люфте a steering wheel it is necessary to check up draughts of a steering, the steering mechanism and люфт bearings of a forward suspension bracket.
15 Strongly move steering draughts a hand. Spherical hinges should not have люфта, otherwise replace hinges or steering draughts.

Check of tips of steering draughts and spherical support

16 Shine with a lamp dusterи the top and bottom spherical support at the left and on the right and check up, whether they are damaged.

17 Shine with a lamp duster (marksman) and a protective cover on both steering draughts and check up, whether they are damaged.

18 Check up reliability of an inhaling of a nut, without turning it thus.
19 With force move a hand steering draughts at the left and on the right. Hinges should not have люфтов. Otherwise replace the corresponding hinge.
20 In the presence of damages duster replace the corresponding hinge with dusterом. Проникшая in the hinge the dirt destroys it.
