The torque is transmitted to the front wheels from the front axle gearbox through the right and left drives

Both drives are identical in design. Each drive consists of shaft 4 (Fig. 1) and two constant velocity joints mounted on its splined ends.

Fig. 1. Front wheel drive: 1 - inner joint housing; 2 - retainer; 3 - boot mounting clamp; 4 - wheel drive shaft; 5 - protective casing; 6 - protective cover; 7 - thrust ring of the cage; 8 - separator; 9 - clamp; 10 - ball; 11 - cage of the outer joint; 12 - retaining ring; 13 - housing of the outer joint; 14 - casing fastening clamp

The housing of the inner hinge 1 is connected to the half-axle gear of the front axle gearbox.

The housing of the outer hinge 13 is connected to the front wheel hub.

The sleeve 11 is connected to the housing 13 through balls 10, which are located in the grooves of the housing and the sleeve.

The sleeve is installed on the splines of the shaft 4, rests against the ring 7 and is fixed on the shaft with a retaining ring 12.

In the compressed state, this ring freely passes through the splined connection of the sleeve 11, which allows both connecting and disconnecting the hinge and the shaft.

The housing of the inner hinge 1 differs from the housing of the outer hinge 13 in that it has straight grooves.

Possible malfunctions and methods of correction

Cause of malfunction

Remedy

Noise, knocking from the front axle when the car is moving (especially when turning)

Worn parts of the outer joint of the front wheel drive

Replace worn or damaged joints

Deformation of the wheel drive shafts

Replace the shafts

Grease leakage

Damage or rupture of the protective boot of the inner or outer joints

Replace the grease in the joint and the protective boot. If parts are worn or damaged, replace the joint assembly
