Figure 6.123. GKN outer joint
The front wheel drive consists of an outer and inner constant velocity joint (CV joint) connected to each other by a shaft. The outer joint transmits torque and provides angular movements of the front suspension and turning of the front wheels. The inner joint transmits torque and provides angular movements of the front suspension. Two types of drives are installed on the car: manufactured by GKN (figure 6.123 and 6.124) and PSA production (figure 6.125 and 6.126).

Figure 6.126. Tripod type PSA internal hinge: 1 - body
Building 1 (see figure 6.126) the hinge can be made of treated or untreated steel. There is an option when the hinge body is connected to the tail by welding.
Mudguards
Figure 6.127. Outer hinge with thermoplastic cover: 1 - mudguard
In mudguards 1 (figure 6.127) thermoplastic is filled with TOTAL N3945 grease. This grease is dark gray in color. It is supplied in a package with green marks.
Figure 6.128. Inner hinge with neoprene cover: 1 - mudguard
Mudguards 1 (figure 6.128), made of neoprene, look like rubber. On the latest cars, these covers are installed only on the gearbox side. These covers are filled with BERUTOX GGF61 grease. Fresh grease is beige.
Attention! TOTAL N3945 and BERUTOX GGF61 lubricants cannot be mixed.
Figure 6.129. Installing rings on the cover: 1 - rings
On some models, covers are installed with rings 1 (figure 6.129) to prevent rupture of covers under the action of centrifugal forces.
Figure 6.130. Variants of mounting belts for covers
To secure to the hinge body, mudguards may have one or two belts, as shown in Figure 6.130.
Figure 6.131. Options for attaching mudguards: A, B, C - options for attaching covers
Mudguards can be glued to the mudguard holder - options A and C (figure 6.131) or put on a cover holder and secured with clamps - option B.
Front Wheel Drive Markings
Figure 6.132. Front wheel drive markings: A - marking places
Front wheel drives are marked using engraving or stickers containing 5 characters. The marking is applied in places A (figure 6.132).
