We remove and repair the wheel driveshafts in the event of damage or to replace the joints and their boots.
We also remove the driveshafts when access to other units is required.
To carry out the task, a spanner and an 18 mm socket, 13 mm and 30 mm sockets, a wheel bolt spanner, a pry bar, a punch and a hammer are required.
Removal of the front wheel driveshafts of the 4х4 vehicle
We prepare the vehicle and place it on a lift or an inspection pit.
We undo the wheel securing bolts on the side being worked on and remove the wheel.
With the hammer handle, we push out the decorative cover of the wheel rim.
We remove the decorative cover.
We refit the wheel and secure it with two opposite bolts.
We lower the vehicle onto its wheels and apply the parking brake.
Using a 30 mm socket, we slacken the wheel hub bearing securing nut, the assistant must press the brake pedal.
After this, we jack up and remove the wheel.
Inserting a screwdriver into the opening of the brake disc and resting it on the brake pad guide, we finally undo the wheel hub bearing securing nut.
The nut will need to be replaced after the repair. Usually the nut is sold with the CV joint kit.
If the nut is missing, the old nut can be temporarily used, but before fitting it, the tabs of the nut collar should be compressed in a vice.
We remove the wheel and place the front part of the vehicle on a stand.
We withdraw the rubber grommets of the speed sensor wires and the brake hose from the bracket.
We disconnect the anti-roll bar link from the shock absorber bracket.
We undo the nuts of the bolts securing the front suspension arm to the subframe and withdraw the bolts.
It is possible (instead of disconnecting the arm from the subframe) to disconnect the ball joint pin from the steering knuckle.
We move the steering knuckle with the shock absorber aside and withdraw the splined shank of the outer joint housing from the wheel hub.
At the same time, the wheel driveshaft must be held against axial movement so that the tripod does not come out of the inner joint housing.
Resting the pry bar on the gearbox housing, we push the inner joint housing out of the gearbox.
We remove the left front wheel driveshaft.
In the connection of the splines of the hub part of the inner driveshaft housing of the right wheel and the idler shaft of the transfer gearbox there is no retaining ring, the splined connection having a tight fit.
When removing the right wheel driveshaft, we rest the pry bar on a tube fitted on the bolt head and, applying the necessary force, move the inner joint housing off the splines of the idler shaft of the transfer gearbox.
We remove the right wheel driveshaft.
We install the driveshafts in the reverse order.
When installing the right front wheel driveshaft, the splines of the idler shaft of the transfer gearbox should be coated with plastic grease.
The sealing ring fitted on the idler shaft of the transfer gearbox should be replaced if it is damaged.
Removal of the front wheel driveshafts of the 4х2 vehicle
The operations for removing the left wheel driveshaft are the same as on the 4х4 vehicle.
The main operations for removing the right wheel driveshaft are the same as on the 4х4 vehicle.
The difference is that before removing the right wheel driveshaft, we undo the bolt securing the intermediate support cover and turn it on its axis, freeing the bearing.
We install the front wheel driveshafts in the reverse order.
Removal of the outer joint and replacement of the boot
We remove the front wheel driveshaft as described above.
We clean the joint housing and the boot from dirt and place the driveshaft on the workbench.
Placing the blade of a flat-blade screwdriver at the joint of the lock of the large clamp, we strike with a hammer on the handle of the screwdriver.
Having opened the clamp lock, we remove the clamp.
Placing the blade of a flat-blade screwdriver at the joint of the lock of the small clamp, we strike with a hammer on the handle of the screwdriver.
We remove the clamp.
We remove the boot from the outer joint housing and move the boot along the shaft towards the inner joint.
We clamp the shaft in a vice and, with a soft metal punch, knock the outer joint off the splines of the driveshaft, striking the end face of the cage.
We remove the outer joint from the shaft.
We remove the rubber boot from the shaft.
We prise out the retaining ring with a screwdriver.
We withdraw the retaining ring from the groove on the shaft.
If the joint has been removed only to replace the boot (when it is known that it was damaged recently and the CV joint has retained its working capacity), then, without dismantling the joint, we remove the old grease from the joint and wash it in kerosene.
We blow the joint with compressed air.
We examine the balls, the cage, the inner race and the inner cavity of the housing.
Scores, dents, cracks, traces of corrosion on the joint elements are not allowed — such a joint is replaced.
We clean the shaft of old grease and apply a thin layer of new grease to it.
We fit a new joint boot onto the shaft.
We install a new retaining ring in the groove of the shaft.
We place and evenly distribute the required volume of new grease in the cavities of the joint housing and its boot.
We fit the joint onto the shaft and, striking with a hammer through a soft metal spacer on the splined shank of the joint, press the joint onto the shaft.
We check the fixation of the joint cage by the retaining ring.
We check the mobility of the joint — it must move without jamming.
We pull the boot onto the joint housing so that the bands of the boot under the clamps are located at the corresponding places of the shaft and the joint housing.
We secure the joint boot with new clamps.
The design of the factory clamps during the installation of the CV joint does not allow them to be installed in the conditions of a non-specialised car service, since special equipment is required for this.
In this case, for example, universal band clamps for securing CV joint boots, available on the market, can be used.
We install the clamp in the groove of the boot, pull the band with pliers, compressing the clamp.
Having tightly tightened the clamp, we bend the pulled end in the opposite direction.
We check the tightening of the clamp and install the front wheel driveshaft in the reverse order.
Removal of the inner joint and replacement of the boot
We replace the boot of the inner joint of the front wheel driveshaft when the boot is damaged.
The inner joints of the left and right wheel driveshafts differ only in the housing.
All the main work is shown on the inner joint of the left wheel driveshaft.
We remove the front wheel driveshaft as described above.
We clean the joint housing and the boot from dirt and place the driveshaft on the workbench.
We place the screwdriver blade at the joint of the lock of the large clamp, strike with a hammer on the handle of the screwdriver.
Having opened the clamp lock, we remove the clamp.
With a screwdriver we open the lock of the small clamp.
We remove the small clamp.
We pull the boot off the inner joint housing and remove the joint housing.
With the help of two screwdrivers we spread the retaining ring.
We withdraw the retaining ring from the groove on the shaft.
We clamp the driveshaft in a vice.
With a soft metal punch we knock the tripod off the splines of the shaft.
We remove the tripod from the shaft.
When assembling the joint, the tripod must be installed on the shaft so that the groove on the tripod (shown by the arrow) is directed towards the boot.
We remove the boot from the shaft.
We prise out with a screwdriver the retaining ring installed on the shank of the joint housing of the left wheel driveshaft.
We remove it.
We withdraw from the housing the spring together with the thrust washer.
If the spring is broken or has lost its elasticity, we replace it with a new one.
We remove the old grease from the joint housing and wash it in kerosene.
We wipe the joint with a cloth and blow it with compressed air.
We examine the tripod bearings and the inner cavity of the joint housing.
Scores, dents, cracks, traces of corrosion on the joint elements are not allowed — such a joint is replaced.
Before installing a new joint boot, we apply a small amount of grease to the end of the shaft.
Having fitted the boot onto the shaft, we place its band under the small clamp in the groove of the shaft.
We place half of the recommended volume of the required grease and evenly distribute it in the cavity of the joint housing, the other half — in the cavity of the boot.
We install a new retaining ring in the groove of the shank of the joint housing of the left wheel driveshaft.
We fit the joint housing onto the tripod and pull the boot onto the joint housing, placing the band of the boot under the large clamp in the mounting groove of the housing.
We secure the joint boot with new clamps.
We install the front wheel driveshaft in the reverse order.
