1. The driveshaft is used only on all-wheel drive (AWD) models (among the considered row it is the Galant AWD models for 1993 the issue) and serves for torque transmission of the engine to back wheels of the car.
2. A car back also establish to Poddomkratta it on props, prop up forward wheels antiretractable boots.
3. Having got under the car, visually estimate a driveshaft condition. In case of identification of deformations and cracks replace a shaft.
4. Check the forward and back ends of a shaft for existence of signs of development of leaks. In case of need make replacement of the corresponding epiploon(s).
5. Without getting out from under the car, ask the assistant to rotate back wheels of the car, having caused thereby rotation of the driveshaft, - hinges have to be turned freely and silently. Estimate a condition of a rubber element of assembly of the central bearing, replace defective components.
6. The condition of cardan hinges can be checked also at a motionless shaft, - strongly grasp each of sections of the hinge and try to rotate them from each other, - existence of a little noticeable side play testifies to wear of internal components of hinged assembly.
7. In conclusion estimate reliability of tightening of fixing bolts of a connecting flange and assembly of the central bearing.
8. On all-wheel drive models in a similar manner estimate a condition of the forward driveshaft. Check shaft for existence of leaks through epiploons of the sliding couplings.
9. Taking an opportunity check also for existence of signs of leaks driving shaft / half shafts of driving wheels. Estimate a condition of protective covers of hinges of equal angular speeds. In case of need make replacement of epiploons of differential.
