Removing
To remove, do the following:
- loosen the hub nut on the side of the shaft to be removed;
- loosen the wheel bolts;
- place the car on a lift or raise the front of the car and place safety supports under the body;
- remove the ABS sensor from the wheel (see section «Brake system»);
- completely unscrew the previously loosened hub nut. When turning the wheel, ask an assistant to press the brake pedal and unscrew the nut;
- unscrew the two bolts securing the brake caliper to the steering knuckle, remove the caliper from the brake disc and tie it away from the work area without pulling the brake hose;
- unscrew the steering tip nut and disconnect the tip from the steering knuckle using a puller;
- unscrew the two nuts of the bolts securing the shock absorber strut to the steering knuckle. Remove the top bolt, leaving the bottom one in place for now. Perform further actions depending on the side of the shaft to be removed.
Left drive shaft (vehicles with manual transmission)
To remove, do the following:
- drain the oil from the gearbox housing;
Figure 4.53. Removal of bolts of fastening of a cover of the internal hinge to a transmission
- unscrew the three bolts securing the inner joint boot holder to the gearbox (Figure 4.53);
Figure 4.54. Disconnecting the inner joint from the gearbox (hinge rollers visible)
- pull the wheel hub outward to disengage the inner joint from the side gear splines. In this case, oil may leak from the box. Do not move the hinge rollers from the spikes (Figure 4.54);
- remove the lower shock absorber strut mounting bolt from the steering knuckle and carefully, avoiding damage to the covers, remove the splined part of the outer hinge from the wheel hub. If necessary (in case of tight fit) use a soft metal punch. In extreme cases, use a suitable puller, carefully remove the shaft from the wheel arch;
- Connect the wheel hub with bolts to the shock absorber strut.
Right drive shaft (on all vehicles)
The right drive shaft is removed in the same way as the left. Remove, if provided, the O-ring from the output shaft splines.
Left drive shaft (on vehicles with automatic transmission)
To remove, do the following:
- Pull the wheel hub outward to move the inner shaft pivot away from the gearbox. If necessary, use a large flat head screwdriver as a lever;
- removal of the outer joint is carried out in the same way as on a car with a manual transmission.
Attention! Protect shaft covers from damage. The slightest puncture or tear of the cover contributes to the penetration of water and dirt into the hinge cavity, which immediately disables it. When installing drive shafts, it is recommended to wrap the covers in polyethylene film and secure with adhesive tape.
Installation
Left drive shaft (on vehicles with manual transmission)
Do the following:
- clean the splined parts of the hinges, the hub and the gearbox from dirt and grease;
- install the inner joint in the gearbox housing, while keeping the shaft in a horizontal position. Align the holes in the holder with the holes in the gearbox housing, insert and screw the fastening bolts to the specified torque, making sure that the boot does not twist;
- insert the splined part of the outer joint into the hub until it stops, insert both bolts connecting the steering knuckle to the shock absorber strut (bolt heads must be forward in travel
- car), put washers on the bolts and tighten the nuts to the specified torque;
- install a new hub nut, turning it first by hand;
- perform the remaining operations in the reverse order of removal;
- lower the car, tighten the hub nut to the specified torque;
- add oil if necessary.
Right drive shaft (on vehicles with all types of gearboxes)
Do the following:
- clean the splines of the shafts, hubs and gearboxes. Apply Molykote BR2 grease to the splines of the indicated parts;
Figure 4.55. Installing a new O-ring on the gearbox output splined shaft
- install a new sealing ring on the output shaft of the gearbox and slide it all the way into the stuffing box (Figure 4.55);
- align the splines of the output shaft and the internal hinge of the drive shaft, slide the shaft all the way onto the splined part of the gearbox shaft;
- installation of the outer joint is carried out in the same way as on vehicles with a manual transmission.
Left drive shaft (on vehicles with automatic transmission)
Do the following:
- clean the splines of the shafts, hubs and gearboxes. Apply Molykote BR2 grease to the splines of the indicated parts;
- align the splines of the output shaft of the gearbox and the internal hinge of the drive shaft, slide the shaft until it stops on the splines of the gearbox shaft;
- the rest of the operations are carried out in the same way as on vehicles with a manual transmission.
