2.8. Check of the spherical hinge of a forward suspension bracket
Lift the car a jack, take a wheel hands in position of 12 and 6 hours and try to shake it in a vertical plane. Very small люфт wheels it is admissible, but if люфт enough big, the further check is necessary to establish a source. Continue to swing a wheel while the assistant presses a foot brake. If люфт it is eliminated or nave bearings are considerably reduced, possibly damaged. If люфт it is still considerable with the pressed brake, means, there is a deterioration in connections and suspension bracket fastenings.
Now take a wheel in position of 9 and 3 hours and try to shake it in a horizontal plane. Presence люфта in a horizontal plane can be caused deterioration in bearings of a nave or spherical hinges of steering draught. If internal or external spherical шарнирное connection is worn out, люфт will be obvious.
Levers of a forward suspension bracket with spherical fingers should be replaced if:
- The hinge is weakened;
- The protective cover of the hinge is torn;
- The spherical finger is disconnected from a rotary fist;
- The spherical finger is weakened in a rotary fist.
Check a tightness of a spherical finger in the plug of a rotary fist at each check of the spherical hinge.
Check up an inhaling корончатой nuts. The weakened nut testifies about прослабленном a finger or the increased backlash in the plug of a rotary fist. The worn out or damaged spherical hinges and rotary fists should be replaced.
