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

Components of a steering drive and suspension bracket should be checked regularly – their wear can serve as the reason of excessive and dangerous wear of tires, deteriorations of running characteristics and controllability of the car, and also fuel consumption increase. More detailed information on components of a suspension bracket and system of a steering is provided in Head the Suspension bracket and a steering.

Check of shock-absorbers

 PERFORMANCE ORDER

  1. Park the car on an equal platform, switch off the engine and cock the parking brake. Check pressure of a rating of tires.
  2. Press a hand one of corners of the car and release a hand. Pay attention to body movement. It should cease to shake and come back to a starting position after one or two fluctuations.
  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 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 props.
  6. Examine shock-absorbers on existence of signs of leakage of 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.
  7. Check reliability of installation and integrity of shock-absorbers. Check the top support of racks on existence of damages and wear signs. In case of detection of those replace racks.
  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 bridge. If it is possible, try to replace all four components in a set.

Check of other components of a suspension bracket and steering

 PERFORMANCE ORDER

  1. Examine components of system of a steering on existence of damages and deformations. Pay attention to the damaged protective covers.
  2. Clear a rotary fist of dirt in the field of a spherical support of a suspension bracket. 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 of a suspension bracket. Examine boots of spherical support of a suspension bracket on existence of gaps. At detection люфта or the torn boots, it is necessary to replace a spherical support and its boot.
  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 tips of steering drafts. Weakened fastenings tighten. Worn-out hinges (check at first reliability of a tightening of nuts) can be the reason of the weakened helmsmen of drafts. Check a condition of boots of the steering mechanism of spherical hinges of tips. If boots of tips are torn, replace them together with tips. Additional information on system of a steering and a suspension bracket can be found in Head the Suspension bracket and a steering.

Check люфта steering

 PERFORMANCE ORDER

  1. Establish a steering wheel in the provision of rectilinear movement.
  2. Rotate a steering wheel here and there, watching thus forward wheels. The steering wheel can have maximum люфт 25 mm.
  3. At bigger люфте a steering wheel check drafts of a steering and the steering mechanism.
