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.

Check of shock-absorbers


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 or weakened shock-absorber.
4. Repeat the procedure described above for each of three remained corners of the car.
5. Поддомкратьте the car and reliably establish it on support.
6. Examine 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 the shock-absorber, instead of whence still. If it nevertheless leak from the shock-absorber, replace shock-absorbers in steam on one axis (or all four).
7. Check up reliability of installation and integrity of shock-absorbers. Check up the top fastenings on presence of damages and deterioration signs. In case of detection of those replace shock-absorbers.
8. In case of need replacements of shock-absorbers address for instructions to the Head the Suspension bracket and a steering. Always replace both components on one axis, 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


1. 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.
2. 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).
3. 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 the Suspension bracket and a steering.

Check пыльников tips of steering draughts and spherical support


1. Lift and establish a forward part of the car on supports.

2. Check up protective caps on the right and at the left. Pay attention to greasing traces.

3. In the presence of cap damages replace the corresponding hinge. The pronikshaja dirt leads to hinge destruction.

Check люфта a steering wheel


1. Establish a steering wheel in average position.

2. Through an open window turn a steering wheel every which way. The steering wheel free wheeling (at motionless wheels) on external diameter should not be more than 25 mm.

3. At the increased free wheeling of a steering wheel it is necessary to check up steering draughts, the steering mechanism and backlashes in bearings.
4. Move with force steering draughts every which way. A backlash in spherical hinges should not be. Otherwise it is necessary to replace hinges or steering draughts.
