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 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 the Head Podvesk and a steering.


Check of the rack/shock-absorber

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 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, the worn-out or weakened rack of a suspension bracket or the 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 racks/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 rack/shock-absorber, but not from where still. If it nevertheless leak from the rack/shock-absorber, replace racks or shock-absorbers in couple on one bridge (or all four).
7 Check reliability of installation and integrity of racks/shock-absorbers. Check the top support of racks for existence of damages and signs of wear. In case of detection of those replace racks or shock-absorbers.
8 In case of need of replacement of racks or shock-absorbers address for instructions to the Head Brake system. Always replace both components on one bridge, otherwise there can be a car threat to security. 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


9 Examine components of system of a steering on existence of damages and deformations. Look for signs of leak of liquid, the damaged laying, protective covers and nipple connections.
10 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.
11 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 weakened fastening of the steering mechanism and hinges of steering drafts. If weakened fastenings, tighten them. If weakened steering drafts, worn-out hinges can be the cause (check at first reliability of a tightening of nuts). Additional information on system of a steering and a suspension bracket can be found in the Head Brake system.

Check of a side play of a steering


12 Establish a steering wheel in average situation.

13 Move a steering wheel here and there, watching thus forward wheels. The steering wheel can have a side play no more than 25 mm.


14 At a bigger side play of a steering wheel it is necessary to check drafts of a steering, the steering mechanism and a side play of bearings of a forward suspension bracket.
15 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 and spherical support

16 Light with a lamp boots of the top and lower spherical support at the left and on the right and check, whether they are damaged.

17 Light with a lamp a boot (shooter) and a protective cover on both steering drafts and check, whether they are damaged.


18 Check reliability of an inhaling of a nut, without turning it thus.
19 With a force move a hand steering drafts at the left and on the right. Hinges should not have side plays. Otherwise replace the corresponding hinge.
20 in the presence of damages of a boot replace the corresponding hinge with a boot. The dirt which got into the hinge destroys it.
