3. Measure the wheel bearing starting torque by

using the following special tools.

• Torque wrench (MB990685)

• Preload socket (MB990326)

Limit: 1.6 N

⋅m <4A9>, 1.76N⋅m <4G1>

4. The starting torque must be within the limit and

245 ± 29 N·m

Tighten the nut
with the bolt
secured

1. Measure to determine whether the wheel bearing

axial play is within the limit or not by using the
following special tools.

• Front hub remover and installer (MB991017)

• Spacer (MB991000)

Limit: 0.05 mm

2. If the play is not within the limit range while the nut

is tightened to 245

± 29 N⋅m, the bearing, hub

and/or knuckle have probably not been installed
correctly. Replace the bearing and re-install.
