The outer joint consists of a housing 1, a separator 2, an inner race 6 and six balls 4. Grooves for accommodating the balls are made in the joint housing and in the race. The grooves in the longitudinal plane are made along the radius, which provides an angle of rotation of the outer joint of up to 42°. The splined tip of the joint housing is installed in the hub of the front wheel and is secured to it with a nut. The race 6 of the joint is installed on the splines of the shaft 9 and is fixed with a locking ring 3.
The inner hinge differs from the outer one in that the tracks of the housing 11 and the sleeve are made straight, not radial, which allows the hinge parts to move in the longitudinal direction. This is necessary to compensate for the movements caused by vibrations of the front suspension and the power unit. Sleeve 6 of the hinge is installed on the splines of the shaft and is fixed with a locking ring.
A selective method is used when assembling the inner hinge. Balls of the same sorting group are installed in the outer and inner hinges. Replacing any one part is not allowed - the hinges are replaced as a whole.
The hinge parts are lubricated with SHRUS-4 grease, which is placed in the hinge housings and covers during assembly. The hinges are sealed with protective covers that are secured with clamps.
Possible wheel drive faults, their causes and methods of elimination are given in Table 11.
