General information about drive shafts

Drive shafts transmit torque from the engine, gearbox and differential to the front wheels. In the gearbox housing, the drive shafts are splined to the side gears of the differential. Fixing the splined tip of the internal hinge of the drive shaft in the side gear is carried out by means of a spring retaining ring. When installed, the retaining ring is compressed, entering the groove of the shaft. After the shaft is fully installed in the side gear of the differential, the retaining ring is unclenched and fixes the splined tip from axial movement. The outer hinges of the drive shafts are attached to the front wheel hubs mounted on bearings. The shaft is attached to the hub with a nut.

On the drive shaft from the differential side there is a universal joint of equal angular velocities (SHRUS) tripod type, providing a low level of vibration.

The constant velocity joints are protected by rubber boots, which are fastened with clamps and protect against water and dirt.

Covers should be periodically inspected for signs of damage, leakage of lubricant or cuts. Damaged CV joints must be replaced immediately with new ones, otherwise the CV joints may be damaged. Replacing the cover includes the operation of removing the drive shafts. Signs of worn or damaged CV joints, in addition to lubrication leaks, are clicks when driving and cornering, hum when accelerating after coasting, or vibration at high speeds on the highway.

Use table 3.8, below for troubleshooting. The numbers prioritize the likely cause of the failure. Check each part in order. Replace these parts if necessary.
