3.14. Survey of components of a suspension bracket and a steering drive, check of a condition of protective covers of power shafts

The condition of components of a suspension bracket and steering drive should be made regularly as their deterioration or damage can be at the bottom of reduction of service life of tyres, conduct to decrease in controllability of the car and increase of the expense of fuel.


Check of a condition of shock-absorbers

 PERFORMANCE ORDER

  1. Park the car on an equal horizontal platform, whenever possible with a firm covering. Firmly cock a lay brake and check up pressure of a rating of tyres.
  2. Press downwards one of car corners. At release a corner the body should come back in a starting position, making no more than one-two fluctuations.
  3. Rocking of a body with high degree of probability testifies to deterioration or easing of the corresponding shock-absorber.
  4. Repeat procedure, serially passing to the remained corners of the car.
  5. Поддомкратьте the car also establish it on props (the Scheme of an institution of props for car fixing in the lifted position see an illustration).
  1. Attentively examine shock-absorbers on presence of signs of leaks of a liquid. Presence of a thin oil film should not cause anxiety. Without fail make sure that a leak source is the shock-absorber, in case of need make replacement of shock-absorbers in the complete set (forward and back).
  2. Check up reliability of fastening of shock-absorbers on the support. In case of revealing of defects replace shock-absorbers (also in the complete set).


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

The design of a suspension bracket and steering drive of cars Infiniti QX4 is presented in the Head the Suspension bracket and a steering.

 PERFORMANCE ORDER

  1. Visually check up components of a suspension bracket and a steering drive on presence of deformations and mechanical damages. Estimate a condition of sealing cuffs, protective covers and резинометаллических plugs, — try not to pass signs of development of leaks.
    • Check up a condition of protective covers картера the steering mechanism.
    • Check up a condition dusterов шарнирных tips of steering draughts.
    • Check up a condition dusterов spherical support.
  1. Clear of dirt traces the bottom surface of a rotary fist, ask the assistant to grasp a bottom edge of a wheel and to pull it in a cross-section direction. Try to estimate visually люфт in spherical support of connection of a fist with a suspension bracket control lever. At presence люфта the worn out hinge is subject to replacement.
  1. Grasp forward and back edges of a wheel, then press on a first line and pull on itself back. In case of revealing люфта in joints of components of a steering drive check up a condition of tips of steering draughts. Deterioration of external tips can be revealed visually, internal — to the touch through a protective cover of the steering mechanism (at wheel rocking). Pass to other board of the car and repeat procedure, having pulled an opposite wheel.
  1. Having lowered the car on the earth, estimate size люфта a steering wheel. From under the car visually estimate inertness of operation of a steering drive at steering wheel rotation (the help of the assistant is required).


Check люфта a steering

 PERFORMANCE ORDER

  1. Establish a steering wheel in average position.
  2. Повращайте a steering wheel in both parties, observing thus of forward wheels. The steering wheel can have maximum люфт 25 mm.
  3. At excessive люфте a steering wheel it is necessary to check up a condition of draughts of a steering drive, the steering mechanism and to estimate size люфта bearings of a forward suspension bracket.
  4. Strongly move steering draughts a hand. Spherical hinges should not have люфта. In case of need replace corresponding components.


Check of a condition of wheel bearings

 PERFORMANCE ORDER

  1. Pull a forward wheel both hands at the top and bottom edges, — presence a little appreciable люфта testifies to easing / damage of the wheel bearing or suspension bracket components. Ask the assistant to squeeze out firmly a pedal of a foot brake and repeat check, — if люфт will disappear, or it will be reduced to a minimum level, hence, it is necessary to be engaged in the bearing, otherwise check up a condition of knots of a joint of components of a suspension bracket.
  2. Grasp forward and back edges of a wheel and repeat the check described above, — if at squeezing of a brake pedal люфт disappears, it is necessary to tighten or replace ступичный the bearing, otherwise check up a condition of components of a steering drive.


Check of a condition of protective covers of power shafts

Established from both ends of each of power shafts the goffered rubber covers urged to protect hinges of equal angular speeds (SHRUS) from the destructions connected with hit in them of a dirt. Hit of oil and greasing on a surface of covers can lead to their premature destruction. It is expedient to wash out from time to time covers a solution of soap water. In view of constant выгибания at turns of wheels, covers of external SHRUS wear out faster and should be checked more often and more regularly.

 PERFORMANCE ORDER

  1. Attentively check up covers on presence of cuts, cracks and other damages, estimate reliability of fixing by their bandage tapes. In case of revealing of defects, or traces of leaks of greasing the damaged cover is subject to replacement.
