If the vehicle is equipped with anti-lock brakes (ABS), disconnect the wiring harness connector from the wheel speed sensor.
Disconnect the left tie rod from the steering arm.
Loosen the shock absorber strut mounting nut and unscrew the nut to the end of the thread, but do not remove it.
Disconnect the ball joint from the steering knuckle by pressing the lower arm down and overcoming the elastic resistance of the stabilizer bar.
Move the shock absorber strut slightly to the side while simultaneously removing the outer constant velocity joint shaft from the hub.
If you cannot remove the shaft by hand, tap it out of the hub with a hammer through a spacer made of soft metal or wood.
Make sure the drive shaft does not come out of the axle gear; this may cause the constant velocity joint rollers to fall into the transmission housing.
Remove the three bolts securing the inner joint boot bracket to the transmission housing.
Remove the inner joint from the half-shaft gear slots and remove the drive.
When removing the joint from the half-shaft gear, check by hand how tightly the rollers fit on the three-pin joint hub journals.
If they move loosely, remove the drive carefully to avoid dropping the rollers into the transmission housing.
Also exercise caution when reinstalling Drive.
Install the left front wheel drive and all removed parts in the reverse order of removal.
After installing all parts, fill the gearbox with oil.
Install the wheel and tighten the wheel bolts until they stop, but do not tighten them completely.
Remove the vehicle from its jack stands and tighten the hub nut.
Final tightening of the hub nut should be performed with the vehicle on the ground; the tightening torque should be 280 Nm (28 kgf/m). Do not move the vehicle with a loose hub nut to avoid damaging the wheel bearing retainer.
Do not reuse hub nuts.
Tighten the wheel bolts.

Repairing Wheel Drive Joints
Repairing constant velocity joints involves Replacing their parts and boots
Immediately replace the hinge boots at the first sign of damage (even in the case of pinpoint punctures, which are diagnosed by the leakage of grease on the boot surface).
In many cases, even cleaning the hinge and replacing the grease in it will help avoid replacing an expensive component.
Only inner hinges can be repaired by replacing parts.
If the outer hinges fail, they will have to be replaced completely along with the drive shaft, since the shaft is made integral with the hinge sleeve.
During operation, only the boots of the outer hinges can be replaced (including replacing the grease).
To repair the hinges, you will need: a circlip puller or round-nose pliers with thin jaws bent at an angle of 90°, fine-nosed pliers, side cutters, or a hacksaw Metal for removing the boot mounting clamps, a punch, a hammer, and a flat-blade screwdriver.
To repair the left front wheel drive inner joint, do the following.
Remove the joint hub retaining ring by spreading it with a retaining ring plier or round-nose pliers and removing the ring from the shaft groove.
Slide the hub and rollers along the shaft splines.
Remove the hub from the shaft.
Mark the position of the hub relative to the shaft and, when reassembling, align it according to the marks.
If installing a new hub, orient it according to the marks on the old hub.
Remove the boot mounting clamp with pliers
The boot mounting clamp can be (and much more easily) removed by cutting it with side cutters, since a new one is always included in the joint repair kit. Clamp.
Remove the boot and its holder from the drive shaft.
If the seal needs to be replaced (in case of an oil leak from the gearbox), knock it off the shaft with hammer blows through a wooden block.
Using a suitable mandrel (it can be made from a pipe), press the new bearing assembly onto the shaft, maintaining a dimension of (118 + 0.2) mm between the ends of the shaft and the bearing.
When pressing the bearing assembly, proceed carefully. To avoid damaging the bearing and seal, press the bearing assembly onto the shaft using a press rather than hammering.
Install the boot on the shaft, secure it with a clamp, press the joint hub assembly with rollers onto the shaft splines (you can use a suitable socket from the tool kit as a mandrel), aligning the marks made during disassembly, and install the snap ring.
To repair the inner joint Right front wheel drive:
Remove the mudguard washer from the joint housing tailpiece.
Remove the large boot mounting clamp by bending it back antenna with a screwdriver
grasping the clamp with thin-nose pliers.
To make it easier to remove the clamp, you can cut it with a hacksaw for metal, since it contains The joint repair kit always includes a new clamp.
