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 a rack shock-absorber
|
|
|
1. The car and reliably establish to Poddomkratta it on support.
2. Examine depreciation racks of a suspension bracket on existence of signs of development of leaks.
3. Check reliability of installation and integrity of racks. Check the top support of racks for existence of damages and signs of wear. In case of detection of those replace racks. |

Check of a condition of system of steering and suspension bracket
|
|
|
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 a side play of steering
|
|
|
1. Establish a steering wheel in average situation.
2. Move a steering wheel here and there, watching at the same time forward wheels. The steering wheel can have the maximum side play of 25 mm.
3. At a bigger side play of a steering wheel it is necessary to check drafts of steering, the steering mechanism and a side play of bearings of a forward suspension bracket.
4. Strongly move steering drafts a hand. Spherical hinges should not have a side play, otherwise replace hinges or steering drafts. |
|
Check of tips of steering drafts, spherical support and covers of the steering mechanism
|
|
| 1. Light with a lamp boots of the lower spherical support at the left and on the right and check for existence of damages. |
|
| 2. Light with a lamp a boot of a tip of steering draft at the left and on the right and check for existence of damages. |
|
3. In the presence of damages of boots for reasons of safety it is necessary to replace the corresponding hinge with a boot. Pollution destroy the hinge.
4. Strongly move steering drafts a hand in different directions. The hinge should not have side plays. Otherwise it is necessary to replace a tip of steering draft.
5. Check reliability of an inhaling of lock-nuts of tips of steering drafts and a nut of fastening of a finger of the hinge, without rotating it. The moment of an inhaling is given in Specifications. |
6. Check protective covers at the steering mechanism, if necessary replace on
new. |
