Vibration of the transfer case and body floor (in the front seat area) when starting the car from a standstill and accelerating to 80 km / h
Cause of malfunction | Elimination Method |
1. The transfer case is not centered relative to the power unit. | 1. Center the transfer case. |
2. Loose or damaged transfer box mountings and powertrain rear mounting. | 2. Tighten the nuts and bolt of the supports, replace the damaged supports. |
3. Tight turning or jamming in one of the planes of the hinges of the front or rear propeller shafts. | 3. Repair universal joints or replace shaft assemblies. |
4. Incomplete release of the parking brake. | 4. Adjust the parking brake. |
5. Tight rotation of the hinge of equal angular velocities of the intermediate shaft. | 5. Check up a condition of a cover and the hinge. If parts of the hinge are damaged, replace it. |
Vibration of the transfer case and body floor (in the front seat area) in the steady state of motion (most characteristic at a speed of 80-90 km / h)
Cause of malfunction | Elimination Method |
1. Increased imbalance of cardan shafts. | 1. Replace or repair cardan shafts. |
2. Increased imbalance of the center differential of the transfer case. | 2. Replace or repair center differential. |
3. Jamming of the cardan joints of the front or rear cardan shafts. | 3. Repair joints or replace driveshaft assemblies. |
4. Jamming of the hinge of equal angular speeds of the intermediate shaft. | 4. Check up a condition of a cover and the hinge. If parts of the hinge are damaged, replace it. |
5. Loose engine mount nuts and bolts or damaged engine mounts. | 5. Tighten the nuts and bolts of the mounts or replace the motor mounts. |
6. Bending of the bolts and flange of the intermediate shaft flexible coupling. | 6. Replace bolts or intermediate cardan shaft. |
Noise when cornering or spinning wheels
Cause of malfunction | Elimination Method |
1. Tight rotation of satellites on the axis. | 1. Replace worn or damaged parts. |
2. Jamming of the axle drive gears in the differential housing. | 2. Replace worn or damaged parts. |
3. Damage to the working surface of the axis of the satellites. | 3. Replace worn or damaged parts. |
4. Large axial clearance of the axle drive gears in the differential housing. | 4. Use shims to set a gap of 0-0.10 mm. |
Difficulty shifting or differential lock
Cause of malfunction | Elimination Method |
1. Clutch stuck on hub splines or differential housing splines. | 1. Remove burrs, nicks or burrs, replace worn parts. |
2. Nicks on the teeth of the small crown of gears of higher or lower gears, as well as on the teeth of the couplings and on the splines of the front axle drive shaft. | 2. Remove nicks and burrs, replace unusable parts. |
3. Bent fork or stem. | 3. Straighten deformed parts. |
4. Deformation of the transfer case drive levers. | 4. Straighten the levers, if necessary, replace them with new ones. |
5. Jamming of the drive levers on the axles. | 5. Remove levers, clean axles and bushings. Replace defective parts. |
Spontaneous disengagement of gears or differential lock
Cause of malfunction | Elimination Method |
1. Wear of gear teeth and couplings. | 1. Replace worn parts. |
2. Reduced elasticity of the springs of the retainers or wear of the parts of the retainers. | 2. Replace springs or worn parts. |
3. Incomplete engagement of gears and differential lock due to deformation of drive parts or due to nicks on gears, couplings and splines. | 3. Straighten or replace deformed parts, clean out nicks and burrs, replace unusable parts. |
Oil leak
Cause of malfunction | Elimination Method |
1. Damaged gaskets. | 1. Replace Gaskets. |
2. Loosening the nuts and studs securing the covers to the crankcase. | 2. Tighten nuts and studs at leaks. |
3. Worn or damaged shaft seals. | 3. Replace oil seals. |
4. Wear of the sealing rings of the transfer case drive rods. | 4. Replace O-rings. |
