• 1 - external hinge of equal angular velocities,
• 2 - retaining ring,
• 3 - thrust ring,
• 4 - washer,
• 5 - collar,
• 6 - protective cover,
• 7 - collar,
• 8 - drive shaft,
• 9 - clamp,
• 10 - protective cover,
• 11 - clamp,
• 12 - cover,
• 13 - square sealing ring,
• 14 - o-ring of circular cross-section,
• 15 - retaining ring,
• 16 - roller,
• 17 - three-arm roller holder,
• 18 - bolt M10x20, 80 Nm,
• 19 - hinge body

Warning: The outer CV joint 1 must be replaced if it fails. When installing on the drive shaft, press the CV joint with a plastic hammer until it is fixed with a retaining ring.

Warning: When installing circlip 2, a new circlip must be used. Before installing the CV joint, the retaining ring is installed in the groove of the drive shaft.

Warning: The concave side of the washer 4 must be in contact with the thrust ring.

Warning: When installing collar 5, a new collar must be used.

Warning: In the presence of scuffs and cracks, a new protective cover must be used 6.

Warning: A 13 square o-ring is supplied with a repair kit.

Warning: O-ring 14 is not required for assembly.

Warning: The chamfer on the splines of the roller holder 17 must point towards the drive shaft.

Removing

Warning: Under no circumstances should the vehicle be lowered onto the wheels with two or one of the drive shafts removed, as this will damage the wheel bearings. If it is necessary to install the vehicle on wheels and move it with the drive shafts removed, install an external drive shaft joint instead of the drive shaft and tighten the joint mounting bolt to 50 Nm.

1. With the vehicle on wheels, loosen the driveshaft outer pivot bolts to the front wheel hubs.

2. Raise the front of the car and secure it on stands.

3. Remove the front wheels.

4. Unscrew bolts of fastening of external hinges of power shafts to naves of forward wheels.

5. Unscrew the bolts (1), (see fig. Location of the bracket for attaching the ABS sensor wire (arrow)), fastening the internal hinges of the drive shafts to the drive flanges of the gearbox. Remove the ABS sensor wire from the bracket on the brake caliper.

6. Unscrew the nut (1), remove the bolt and pull up to remove the upper control arms (2) from the steering knuckle, see fig. Elements of the top fastening of a rotary fist.

Warning: Do not expand the slots in the steering knuckle when removing the upper transverse arms. It is forbidden to unscrew the bolts securing the tie rod to the steering knuckle, otherwise it will be necessary to adjust the angles of the front wheels (3 and 4), see fig. Elements of the top fastening of a rotary fist.

7. Tilt the top of the steering knuckle to the side (arrow), see fig. Elements of the top fastening of a rotary fist.

8. Remove the drive shaft.

Installation

1. Install the drive shaft to the vehicle and connect it to the transmission drive flange and hub.

Warning: When installing a drive shaft with a three-arm joint, do not move the joint back. Before installation, using adhesive tape, secure the joint to the drive shaft. Before screwing the drive shaft flange, remove the adhesive tape.

2. Install the driveshaft-to-hub bolts, finger-tight at this stage.

3. Install the upper transverse arms against the stop in the steering knuckle and secure them with a bolt and nut, tightening them with a torque of 40 Nm (2), see fig. Location of the hole in the spring seat.

4. Screw in and torque-tighten the mounting bolts (M8, M10) driveshaft CV joint to gearbox drive flange, see table Tightening torques.

5. Attach the ABS sensor wire to the brake caliper bracket.

6. Apply a thin layer of grease to the shoulder of the hub that centers the wheel disc. Install the wheel and secure it with bolts. Lower the vehicle and tighten the wheel bolts to 120 Nm.

7. Screw in and torque-tighten the mounting bolts (M14, M16) external joints of the drive shafts to the front wheel hubs, see table Tightening torques.

Warning: Tighten the bolts for fastening the drive shafts to the front wheel hubs only with the vehicle standing on wheels.

Tightening torques

Bolt M8	40 Nm
Bolt M10	50 Nm
Bolt M14	115 Nm + tighten by 180°
Bolt M16	190 Nm + tighten by 180°
