Condition check suspension bracket and steering component

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 Brake system.

Rack shock-absorber check


1. To Poddomkratta the car and reliably establish it on support.
2. Examine amortization racks on existence of signs of damages and leakages of gas.
3. Check reliability of installation and integrity of racks. Check the top support of racks on existence of damages and wear signs. In case of detection of those replace racks.

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 Brake system.

Check люфта steering


1. Establish a steering wheel in average situation.
2. Move a steering wheel here and there, watching thus forward wheels. The steering wheel can have maximum люфт 15 mm.
3. At bigger люфте a steering wheel it is necessary to check drafts of a steering, the steering mechanism and люфт bearings of a forward suspension bracket.
4. Strongly move a hand steering drafts (4) at the left and on the right. The Sharovy hinge (5) should not have люфта, otherwise replace hinges or steering drafts.

5. Shine with a lamp dustproof caps (5) and check on existence of damages. Thus pay attention to greasing traces.

6. In the presence of cap damages from precaution replace the corresponding hinge together with a cap. The got dirt destroys the hinge.

Check of tips of steering drafts, spherical support and covers of the steering mechanism


1. Shine with a lamp boots of spherical support at the left and on the right and check on existence of damages.

2. Shine with a lamp a boot of a tip of steering draft at the left and on the right and check on 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 люфтов. 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 with the new.

7. Check reliability of fastening of external (2) and internal (3) tightening rings.
