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 wear of tires, deteriorations of running characteristics and controllability the car and to fuel consumption increase.

For more detailed information on components of a suspension bracket and system of a steering address to 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 the parking brake. Check pressure in tires.
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 musclemen.
3. If the car continues to be shaken or did not come back to 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. To Poddomkratta the car and reliably establish it on support.
6. Examine shock-absorbers on existence of signs of leakage of hydraulic liquid. The easy film of liquid is not at the bottom for concern. In case of detection of leak make sure that liquid follows from the shock-absorber, instead of from where still. If it nevertheless leak from the shock-absorber, replace shock-absorbers in pair on one axis (or all four).
7. Check reliability of installation and integrity of shock-absorbers. Check the top fastenings on existence of damages and wear signs. In case of detection of those replace shock-absorbers.
8. In case of need replacements of shock-absorbers address for instructions to 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 a set.

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


1. Examine components of system of a steering on existence of damages and deformations. Look for signs of leakage of the liquid, the damaged laying, protective covers and shtutserny connections.
2. Clear the bottom end of a rotary fist. Ask the assistant to grasp bottom edge of a wheel and to shake it, and at this time watch movement of the spherical support connecting a rotary fist to the lever. Examine protective covers of spherical support on existence of gaps. If you find люфт or 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 it a first line inside, and back outside to check existence люфта in a steering drive. If it is found люфт, check, whether weakened fastenings of the steering mechanism and hinges of steering drafts. If weakened fastenings, tighten them. If weakened steering drafts, worn-out hinges (check at first reliability of a tightening of nuts) can be the reason. Additional information on system of a steering and a suspension bracket can be found in Head the Suspension bracket and a steering.

Check of boots of tips of steering drafts and spherical support


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

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

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

Check люфта steering wheel


1. Establish a steering wheel in average situation.

2. Through an open window turn a steering wheel in different directions. The free wheeling of a steering wheel (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 steering drafts, the steering mechanism and gaps in bearings.
4. Move with force steering drafts in different directions. A gap in spherical hinges should not be. Otherwise it is necessary to replace hinges or steering drafts.
