ATTENTION
Irrespective of the used lifting equipment do not use the suspension bracket lever as a support.

Removal
Install the car on the two-rack-mount elevator.
Unblock a steering wheel.
Remove a forward wheel and the side flap.

Fig. 4.34. Untwisting of the lower fastenings of the lever of a forward suspension bracket: 1 – bolt of fastening of a spherical support of the lever of a suspension bracket; 2 – nut of fastening of a finger of the spherical hinge


Turn off a bolt of fastening of a spherical support of the lever of a suspension bracket and a nut of fastening of a finger of the spherical hinge of the end of a bar of the stabilizer of cross stability (fig. 4.34).
Vypressuyte the spherical hinge of a tip of steering draft by means of adaptation (Tav. 476).
Turn off the top bolt of fastening of connecting draft between a stretcher and a longeron.

Fig. 4.35. Untwisting of the top fastenings of the lever of a forward suspension bracket: 1 – top bolt of fastening of connecting draft; 2 – nut of fastening of connecting draft of a stretcher; 3 – bolts of back and forward fastenings of the lever of a suspension bracket


Turn off the lower nut of fastening of connecting draft of a stretcher and bolts of back and forward fastenings of the lever of a suspension bracket (fig. 4.35).
Remove the suspension bracket lever.

Installation
Installation is made as it should be, the return to removal.

ATTENTION
Surely replace bolts of fastening of levers of a suspension bracket.

Fig. 4.36. A tightness exception at an inhaling of saylent-blocks at installation of the lever of a suspension bracket: 1 – cap of a spherical support



ATTENTION
At installation for a tightness exception at an inhaling of saylent-blocks install the suspension bracket lever so that to receive interaxal distance of X1 = 24 mm between the lower part of a spherical support of the lever and the lower part of a stretcher at the level of an opening in the center of the W1 lever (fig. 4.36).

Establish a hydraulic jack under a stretcher in a zone of an average opening of the lever of a suspension bracket W1 and lift it before contact with a stretcher.
Lower a hydraulic jack on the X1 size = 24 mm.
Arrange a cap of a spherical support of the lever of a suspension bracket on a hydraulic jack, without changing position of the lever.
In this situation tighten the required moment 105 N · m bolts of forward and back fastenings of the lever of a suspension bracket to a stretcher.
Remove a hydraulic jack.
Insert a spherical support of the lever of a suspension bracket into a rotary fist.
Establish and tighten the required moment:
– nut of the lower fastening of connecting draft of a stretcher (62 N · l);
– bolt of the top fastening of connecting draft of a stretcher (210 N · l);
– nuts of fastening of fingers of spherical hinges of the ends of a bar of the stabilizer of cross stability (35 N · l);
– nut of fastening of a finger of a spherical support of the lever of a suspension bracket (62 N · l);
– forward wheels and bolts of fastening of a forward wheel (105 N · м).

NOTE
Establish draft of the stabilizer of cross stability by means of adaptation (Sus. 1413) and adapter (Sus. 1734).

ATTENTION
Adjust the angles of installation of wheels.
