Note. The nut needs to be replaced "Nylstop" on the nut "Enko" (installed without the use of tack compound). If the car is already equipped with a type nut "Enko", there is no need to replace it - it can be used four times. On manual transmission models, new roll pins will be required during installation to secure the drive shaft to the differential.
Note. The grooves of the outer CV joint are covered with a tack compound. Therefore, a puller will be required to remove the hub assembly from the end of the drive shaft.
Removing
1. Remove hub cap/wheel cap (depending on the model), then loosen the driveshaft nut and wheel bolts.
2. Block the rear wheels of the vehicle, engage the handbrake, then jack up the front of the vehicle and place it on axle stands. Remove the front wheel.
3. On models equipped with ABS, remove the wheel speed sensor bolts, move it away from the hub assembly and tie it to the body (contact the head Brake system). Please note that there is no need to disconnect the wiring.
4. Turn away a fixing nut of a power shaft. If the nut was not loosened before the vehicle was jacked up, install the two wheel bolts into the hub and tighten them securely. Have an assistant firmly depress the brake pedal to lock the hub, then use the socket and extension rod to loosen and remove the nut. Alternatively, make a forked tool out of two pieces of steel strip (one long, one short), by connecting them with a bolt and nut. Attach the tool to the hub using the two wheel bolts and, while holding it stationary, unscrew the drive shaft mounting nut.
5. Loosen and remove the nut securing the tie rod end to the steering knuckle, then separate the ball joint from the hub using a special puller.
6. If it is necessary to remove the hub bearings, remove the brake disc as described in Chapter Brake system. If not, remove the two bolts securing the caliper bracket assembly to the steering knuckle and remove the caliper from the disc (refer to accompanying illustration). Use a piece of wire or twine to tie the caliper to the front suspension spring so as not to stretch the brake hose. If necessary, remove the wiring bracket/brake hose bolts from the strut.
7. Remove the nut and pinch bolt securing the lower arm to the steering knuckle. Gently press the ball joint away from the steering knuckle, taking care not to damage the ball joint and the drive shaft protective covers. Pay attention to the plastic protective plate mounted on the ball joint shaft.
8. Remove the two nuts/washers from the bolts holding the steering knuckle to the suspension strut, remembering that the nuts are installed from the rear of the strut (refer to accompanying illustration). Remove the bolts and support the steering knuckle assembly.
9. Release the CV joint of the drive shaft from the hub and remove the steering knuckle assembly. Please note that a tack compound is applied to the grooves of the CV joint. Use a hammer and soft metal drift or puller to pry the pivot out of the hub (refer to accompanying illustration). Support the drive shaft so as not to damage the CV joints and their boots.
Installation
1. Clean and dry the grooves of the CV joint and hub, then apply a tack compound to the CV joint shaft (Renault recommends Lostite Scelbloc).
2. Align the grooves of the CV joint and the hub and slide the hub along the drive shaft to the working position. Insert two bolts securing the steering knuckle to the suspension strut (from the front of the rack), then install washers and nuts on them and tighten to Specifications effort (refer to accompanying illustration).
3. Install the washer and fit a new type drive shaft nut "Enko" (see note above).
4. Make sure the plastic skid plate is still on the lower arm ball joint, then install the pivot pin into the steering knuckle. Insert the pivot pinch bolt and tighten the retaining nut to the Specifications effort.
5. Insert the ball joint of the tie rod end into the steering knuckle and tighten the fixing nut as shown in Specifications effort.
6. Insert the ball joint of the tie rod end into the steering knuckle and tighten the fixing nut as shown in Specifications effort.
7. On models equipped with ABS, install the sensor in the hub and tighten the mounting bolt to the specified tightening torque (contact the head Brake system).
8. Install the brake disc, aligning the marks made before removal, and tighten the mounting screws as shown in Specifications effort. Place the brake caliper assembly in working position on the disc. Apply a few drops of tack compound to the threads of the caliper bolts (Renault recommends Lostite Frenbloc), then install the bolts and tighten them to the specified tightening torque (Chapter Brake system, refer to illustration).
9. Block the hub using the same method used when removing the hub and tighten the new driveshaft mounting nut to the torque shown in Specifications effort. Alternatively, lightly tighten the nut at this stage, postponing its final tightening until the vehicle is lowered to the ground.
10. Make sure the hub spins freely, then install the wheel and lower the vehicle to the ground. Tighten the wheel bolts to Specifications effort.
