Pic. 3.148. Disconnecting the ball joint
With a special tool (puller 09568-34000) Disconnect the tie rod end ball joint from the steering knuckle (pic. 3.148).
Note. To prevent the puller from jumping off (09568-34000) pre-tie it with a rope or wire.
Pic. 3.149. Bolt of fastening of a rotary fist
Disconnect the steering knuckle bolt from the lower control arm ball joint (pic. 3.149).
Pic. 3.150. Disconnecting the wheel drive shaft from the wheel hub
Using a plastic mallet, remove the wheel drive shaft from the wheel hub (pic. 3.150).
Remove the front axle assembly.
Disassembly
Remove the two brake disc mounting screws, then remove the brake disc from the wheel hub.
Pic. 3.151. Removal of a lock ring of the bearing of a nave
Remove the wheel bearing snap ring (pic. 3.151).
Pic. 3.152. Installing a special tool on the wheel hub
Establish the special tool on a nave of a wheel, as it is shown in drawing 3.152.
Rotating the special tool, remove the hub from the steering knuckle.
Remove the special tool and protective cover.
Pic. 3.153. Removing the inner race of the bearing from the wheel hub
Using the special tool, remove the inner bearing race from the wheel hub (pic. 3.153).
Pic. 3.154. Removing the outer race of the bearing from the wheel hub
With a special tool (09495-33100 and 09517-29000) remove the bearing outer race from the steering knuckle (pic. 3.154).
Examination
Check the hub for cracks and the hub splines for excessive wear.
Check the brake disc for nicks and damage.
Check the steering knuckle for cracks.
Check the bearing for cracks or damage.
Assembly
Apply a light coat of multipurpose grease to the bearing seats in the hub and steering knuckle.
Pic. 3.155. Pressing the bearing into the steering knuckle
With a special tool (09495-33100 and 09517-29000) press the bearing into the steering knuckle (pic. 3.155).
Note. To prevent damage to the bearing assembly, the pressing force must be applied to its outer race.
Note. Always install a new bearing assembly (do not install a used bearing).
Install the protective cover.
Pic. 3.156. Pressing the hub into the steering knuckle
With a special tool (09495-33100) press the hub into the steering knuckle (pic. 3.156).
Note. To prevent damage to the bearing assembly, the pressing force must be applied to the inner race of the bearing.
Install the brake disc.
Rotate the hub several times to properly install the bearing.
Pic. 3.157. Measurement of the moment of the beginning of rotation of the bearing of a nave of a wheel
Measure the wheel bearing start torque (pic. 3.157)
The maximum permissible value of the moment of the beginning of rotation of the bearing of the hub: 1.8 Н·м or less.
Pic. 3.158. Measuring the axial clearance of the wheel bearing
If the starting torque of the bearing is 0 Nm, measure the end play of the wheel bearing (pic. 3.158).
If the axial clearance is greater than the limit when the special tool nut is tightened to 200–260 Nm, the bearing, hub, and steering knuckle are not installed correctly. In this case, disassemble the assembly and repeat the assembly procedure.
Hub bearing axial clearance: 0.08 mm or less.
Remove special tool (09517-21500).
