The torque from the transmission to driving wheels is transmitted through drive shaft, and on all-wheel drive cars also via the driveshaft.
Each shaft of the drive consists of three parts: internal and external hinges of equal angular speeds (CV JOINTS) and shaft.
Shlitsevy part of the external hinge is inserted into a nave of a wheel and fixed by a nut. CV JOINTS are greased with jellied lubricant which is replaced only when dismantling the hinge.
Covers have to be checked for damages and leak of lubricant periodically.
Lubricant follows from the hinge at a rupture of a protective cover or weakening of collars of its fastening.
Immediately replace the torn protective covers of CV JOINTS, otherwise damage of hinges is possible. Replacement of a cover includes removal of a shaft of the drive.
Vibration and the increased noise at start-off from the place, braking by the engine and on sharp turns arise at wear of hinges of equal angular speeds, shlitsevy connections of a shaft and when weakening an inhaling of bolts of fastening of wheels.
