3.4.1. General information

Power shafts transfer torque from the engine, the transmission and differential to forward wheels. In a transmission case power shafts fasten shlitsevy connections with semi-axial gear wheels of differential. Fixing of a shlitsevy tip of the internal hinge of a power shaft in a semi-axial gear wheel is carried out by means of a spring lock ring. At installation the lock ring contracts, entering a shaft flute. After the shaft will be completely established in a semi-axial gear wheel of differential, the lock ring is unclenched and fixes a shlitsevy tip from axial movement. External hinges of power shafts fasten to naves of the forward wheels established on bearings. The shaft fastens to a nave a nut.

On driving the universal hinge of equal angular speeds (HEAS) of tripodny type providing the low level of vibration is installed to a shaft from differential.

Hinges of equal angular speeds are protected by rubber covers which fasten collars and protect from hit of water and dirt.

Covers should be examined periodically on existence of traces of damages, leak of lubricant or cuts. The damaged covers of CV JOINTS need to be replaced immediately new, otherwise CV JOINTS can be damaged. Replacement of a cover includes operation of removal of power shafts. Signs of wear or damage of the CV JOINT, besides lubricant leak, are clicks at the movement and turns, a rumble at acceleration after the movement on inertia or vibration at high speeds on the highway.

Use table 3.8 given below for search of causes of defect. Numbers define a priority of a probable cause of malfunction. Check each part one after another. In case of need replace these parts.
