Cause of defect
|
Way of elimination
|
|
The raised noise from outside back wheels
|
|
1. Ослабло wheel fastening
|
1. Tighten bolts of fastening of a wheel
|
|
2. Deterioration or destruction of the ball bearing of a semiaxis
|
2. Examine полуось and replace
The bearing
|
|
The constant raised noise at work
|
|
1. A beam of the back bridge bearings of semiaxes are deformed, damaged
|
1. Correct a beam and check up
Its sizes, replace bearings of semiaxes
|
|
2. Semiaxes are deformed and have inadmissible palpation
|
2. Correct semiaxes. If they are considerably damaged, replace new
|
|
3. Deterioration шлицевого connections with semiaxial gear wheels
|
3. Replace the worn out or damaged details
|
|
4. Wrong adjustment, damage or deterioration of gear wheels or reducer bearings
|
4. Define malfunction and repair a reducer
|
|
5. Insufficient quantity of oil
|
5. Restore level of oil and check up, whether there is no leak through consolidations or in a beam of the back bridge
|
|
Noise at car dispersal
|
|
1. Deterioration or wrong adjustment of bearings of differential
|
1. Remove a reducer,
Repair, if necessary replace details
|
|
2. Gearing of teeths of gear wheels of the main transfer at reducer repair is incorrectly adjusted
|
2. Adjust gearing
|
|
3. Damage of bearings of a semiaxis
|
3. Replace bearings
|
|
4. Insufficient quantity of oil
|
4. Restore level of oil and check up, whether is not present подтекания in consolidations or in a beam of the back bridge
|
|
Noise at dispersal and braking of the car by the engine
|
|
1. Deterioration or destruction of bearings of a leading gear wheel
|
1. Replace the damaged details
|
|
2. A wrong lateral backlash between teeths of gear wheels of the main transfer
|
2. Check up gear wheels and replace damaged, having restored a normal lateral backlash between teeths of gear wheels
|
|
Noise at movement on turn
|
|
1. Hard rotation of satellites on an axis
|
1. Replace the damaged or worn out details
|
|
2. Teases on a working surface of an axis of satellites
|
2. A small roughness smooth out thin наждачной a skin, at impossibility to eliminate defect replace an axis of satellites
|
|
3. Jamming of gear wheels of semiaxes in a differential box
|
3. At insignificant damages of gear wheels and the interfaced surfaces to a differential box smooth out them наждачной a skin, the damaged details replace new
|
|
4. A wrong backlash between teeths of gear wheels of differential
|
4. Adjust a backlash
|
|
5. Damage of bearings of semiaxes
|
5. Replace bearings
|
|
Knock in a car start of motion
|
|
1. The increased backlash in шлицевом connection of a shaft of a leading gear wheel with a flange
|
1. Replace a flange and gear wheels of the main transfer
|
|
2. The increased backlash in gearing of gear wheels of the main transfer
|
2. Adjust a backlash
|
|
3. Deterioration of an aperture under an axis of satellites in a differential box
|
3. Replace a differential box
|
|
4. Ослабли bolts of fastening of bars of a back suspension bracket
|
4. Tighten bolts
