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

Components of the steering drive and suspension bracket should be checked regularly. The worn-out or damaged components of a suspension bracket and the steering drive can serve as the reason of excessive and dangerous wear of tires, deteriorations in running characteristics and controllability the car and to increase in fuel consumption.

For more detailed information on components of a suspension bracket and system of steering address the Head Podvesk and steering.

Check of shock-absorbers

 PERFORMANCE ORDER

1. Park the car on the flat 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 the movement of a body. He has to cease to shake and get up 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, then the worn-out or weakened shock-absorber is the possible reason of it.
4. Repeat the procedure described above for each of three remained car corners.
5. The car and reliably establish to Poddomkratta it on support.
6. Examine shock-absorbers on existence of signs of leak of hydraulic liquid. The easy film of liquid is not the reason for concern. In case of detection of leak make sure that liquid follows from the shock-absorber, but not, from where still. If all this leak from the shock-absorber, replace shock-absorbers in couple on one axis (or all four).
7. Check reliability of installation and integrity of shock-absorbers. Check the top fastenings for existence of damages and signs of wear. In case of detection of those replace shock-absorbers.
8. In case of need replacements of shock-absorbers address for instructions the Head Podvesk and steering. Always replace both components on one axis, otherwise there can be a threat to security of the car. If it is possible, try to replace all four components in a set.

Check of a condition of system of steering and suspension bracket

 PERFORMANCE ORDER

1. Examine components of system of steering on existence of damages and deformations. Look for signs of leak of liquid, the damaged laying, protective covers and nipple connections.
2. Clear the lower end of a rotary fist. Ask the assistant to take bottom edge of a wheel and to shake it, and at this time watch the 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 a side play or the torn or proceeding protective covers, the spherical support (support) should be replaced.
3. Take each of forward wheels for forward and back edges and try to turn it a first line inside, and back outside to check existence of a side play in the steering drive. If the side play is found, check whether fastenings of the steering mechanism and hinges of steering drafts weakened. If fastenings weakened, tighten them. If steering drafts weakened, then worn-out hinges can be the cause (check at first reliability of tightening of nuts). Additional information on system of steering and a suspension bracket can be found in the Head Podvesk and steering.

Check of boots of tips of steering drafts and spherical support

 PERFORMANCE ORDER

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 lubricant traces.

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

Check of a side play of a steering wheel

 PERFORMANCE ORDER

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 a force steering drafts in different directions. The gap in spherical hinges should not be. Otherwise it is necessary to replace hinges or steering drafts.
