- Cause of malfunction
Remedy
Knocking in the driveline during a sharp change in the movement of the car or when shifting gears:
- Wear of bearings and spikes of crosses in hinges
Check radial clearance in pivot bearings and if greater than 0.10 mm, replace spider and bearings
- Loose fastening of the shaft to the flange of the rear axle drive gear
Tighten the fastener to the specified torque
Gimbal vibration:
- Lost balance plate
Dynamic shaft balancing
- The splined fork of the intermediate shaft is incorrectly installed
Installing the slotted fork in the same plane as the sliding fork
- The fastening of the intermediate support to the cross member has loosened
Tighten fastening
Increased runout of sliding fork in gearbox extension:
- Wear or breakage of one of the hinges
Initially turn the spline fork 180° and check if the runout is reduced. If it does not decrease, replace worn parts. When replacing the spline fork, balance the shaft dynamically
- Breakage or damage to the rear axle drive gear flange
Replace Hinge
- Cardan shaft tube is bent or removed
Replace flange
- Shaft fastening to the rear axle has loosened
Inspect the shaft, check its runout and, if it exceeds 0.8 mm, straighten it, while its runout should be no more than 0.6 mm at any point along the length. Balance the shaft dynamically. Tighten the mount
Malfunctions that are detected during inspection:
- Turning the cap with the cuff relative to the bearing cup (violation of the tightness of the hinge)
Replace cross with bearing assembly. Balance transmission
- Turning the bearing cup in the fork holes
Replace worn parts, balance gear
