REMOVAL AND INSTALLATION


caution
  • Do not disassemble the front wheel hub assembly.
  • The magnetic encoder collects any metallic particle easily, because it is magnetized. Make sure that the magnetic encoder should not collect any metallic particle. Check that there is not any trouble prior to reassembling it.
  • When the front wheel hub assembly is removed and installed, make sure that the magnetic encoder does not contact with surrounding parts to avoid damage.
Post-installation Operation
  • Check the dust cover for cracks or damage by pushing it with your finger.

REMOVAL SERVICE POINTS

<<A>> DRIVESHAFT NUT REMOVAL
caution Do not apply pressure to wheel bearing by the vehicle weight to avoid possible damage when driveshaft nut is loosened.

Use special tool front hub and end yoke holder (MB990767) to fix the hub and remove the driveshaft nut.

<<B>> CALIPER ASSEMBLY REMOVAL
Secure the removed caliper assembly with wire, etc.

<<C>> BRAKE DISC REMOVAL

If the brake disc is seized, install a M8 x 1.25 bolts as shown, and remove the disc by tightening the bolts evenly and gradually.

<<D>> SELF-LOCKING NUT (TIE ROD END CONNECTION) REMOVAL

1.
caution
  • Do not remove the nut from ball joint. Loosen it and use the special tool to avoid possible damage to ball joint threads.
  • Hang the special tool with cord to prevent it from falling.
Install special tool ball joint remover (MB991897) as shown in the figure.

2.Turn the bolt and knob as necessary to make the jaws of special tool parallel, tighten the bolt by hand and confirm that the jaws are still parallel.
note When adjusting the jaws in parallel, make sure the knob is in the position shown in the figure.
3.Tighten the bolt with a wrench to disconnect the tie rod end.

<<E>> DRIVESHAFT REMOVAL

caution
  • The magnetic encoder collects any metallic particle easily, because it is magnetized. Make sure that the magnetic encoder does not collect any metallic particle.
  • When the driveshaft is removed, make sure that it does not contact with the magnetic encoder to avoid damage.

Use the following special tools to push out the driveshaft from the hub.

  • Puller shaft (MB990242)
  • Puller bar (MB990244)
  • Puller body (MB991354)
  • Front hub and end yoke holder (MB990767)

INSTALLATION SERVICE POINT

>>A<< WASHER/ DRIVESHAFT NUT INSTALLATION
caution
  • The magnetic encoder collects any metallic particle easily, because it is magnetized. Make sure that the magnetic encoder should not collect any metallic particle. Check that there is not any trouble prior to reassembling it.
  • When the driveshaft is installed, make sure that it does not contact with the magnetic encoder to avoid damage.
  • Before securely tightening the driveshaft nuts, make sure there is no load on the wheel bearings. Otherwise the wheel bearings will be damaged.

1.Be sure to install the driveshaft washer in the specified direction.
2.Using special tool front hub and end yoke holder (MB990767), tighten the driveshaft nut to the specified torque.
Tightening torque: 245 ± 29 N·m
