Checks On The Looseness Of Wheel Bearings - Chery QQ Service Manual

Chery QQ Service Manual
11 Installation
1 When making the assembly of the
wheels and tires, first fix the wheel screws onto
the hubs manually and tighten them slightly.
Then use special tools to tighten the screws in
the diagonal sequence till the specified torque
of 110 10N.m is applied. It is not allowed to
use impact wrenches that might cause damages
to the wheels, or insufficient tightness or excessive
tightness. It is not allowed to apply lubricating grease onto the wheel screws. (For the
completed assembly of wheels and tires, the wheel screws should be re-tightened after the
car runs for 100km so that the specified torque is assured. The checks on the torque of the
fixing screws are one of the routine maintenance items).
2 When tightening the screw nuts, the
cross approach is applied. The extent of tightness
should be close to each other, and the wheels should
be able to turn freely. When the final tightening is
made, the wheels should be positioned on the ground.
3 Install the decorated covers or place the decorative covers as needed. When the
clip-type decorative covers are installed, they should be driven in either with hands or by
way of rubber hammering tools.
