4.4.4. Possible malfunctions of the back bridge, their reason and methods of elimination

Cause of defect
Elimination method
The increased noise from back wheels
1. Fastening of a wheel weakened
1. Tighten bolts of fastening of a wheel
2. Wear or destruction of the ball bearing of a half shaft
2. Examine a half shaft and replace the bearing
The constant increased noise during the work of the back bridge
1. The beam of the back bridge is deformed
1. Correct a beam and check it
sizes
2. Half shafts are deformed and have an inadmissible beating
2. Correct half shafts. If they are considerably damaged - replace new
3. Wear of shlitsevy connection with semi-axial gear wheels
3. Replace the worn-out or damaged details
4. Wrong adjustment, damage or wear of gear wheels or bearings of a reducer
4. Define malfunction and repair a reducer
5. Insufficient amount of oil
5. Restore the level of oil and check whether there is no leak through consolidations or in a beam of the back bridge
Noise at dispersal of the car
1. Wear or wrong adjustment
differential bearings
1. Remove a reducer, repair,
if necessary replace details
2. It is incorrectly adjusted zatsepv
main having transferred a leniye of teeths of gear wheels
чи at repair of a reducer
2. Adjust gearing
3. Damage of bearings of a half shaft
3. Replace bearings
4. Insufficient amount of oil
4. Restore the level of oil and check whether there is no dribble in consolidations or in a beam of the back bridge
Noise when braking the car the engine
1. The wrong gap in gearing
between gear wheels of the main transfer
1. Adjust a gap
2. The increased gap in bearings
the leading gear wheel owing to oslablev
niya of a nut of fastening of a flange or wear
bearings
2. Check resistance moment
to provorachivaniye of the leading gear wheel,
tighten a nut or replace povrezhv
day details
Noise at dispersal and braking of the car by the engine
1. Wear or destruction of bearings
leading gear wheel
1. Replace the damaged details
2. The wrong side gap between
teeths of gear wheels of the main transfer
2. Check gear wheels and replace damaged, having restored a normal side gap between teeths of gear wheels
Noise at the movement on turn
1. Hard rotation of satellites on an axis
1. Replace damaged or iznov
tire details
2. Teases on a working surface of an axis
satellites
2. Smooth out a small roughness a thin emery cloth, at not an opportunity to eliminate defect - replace an axis of satellites
3. Jamming of gear wheels of half shafts
in a differential box
3. At insignificant damages
gear wheels and the interfaced surfaces in a differential box, smooth out them an emery cloth, replace the damaged details new
4. The wrong gap between teeths
differential gear wheels
4. Adjust a gap
5. Damage of bearings of half shafts
5. Replace bearings
Knock in a car start of motion
1. The increased gap in shlitsevy connection of a shaft of the leading gear wheel with
flange
1. Replace a flange and gear wheels of the main transfer
2. The increased gap in gearing of gear wheels of the main transfer
2. Adjust a gap
3. Wear of an opening under an axis of satellites in a differential box
3. Replace a differential box
4. Bolts of fastening of bars of a back suspension bracket weakened
4. Tighten bolts
Oil leak
1. Wear or damage of an epiploon of the leading gear wheel
1. Replace an epiploon
2. The wear of an epiploon of a half shaft determined by oiling of brake boards, drums and blocks
2. Check a half shaft beating, a deflection
beams; correct or replace the damaged details. Replace an epiploon
3. Weakening of bolts of fastening of a case of a reducer of the back bridge; damage of sealing laying
3. Tighten bolts; replace condense telny laying
