5.0 WHEEL RE-TORQUE PROCEDURE
5.1
Due to relaxation of the joint, it is vital that
all wheel nuts are rechecked for tightness
after the vehicle has stood for a period of
30 minutes whether the vehicle has moved
or not. Wheel nuts should be rechecked for
tightness after 25-50 miles.
5.3
The re-torque procedure should be carried
out to complete the wheel fitment procedure
in one operation in one operation before the
vehicle is put into service.
4.13
If the wheel nuts have been over
tightened during the run up procedure
(this will be indicated by no movement
of the nut during the torqueing procedure)
the wheel nuts must be slackened off,
re-checked and re-tightened in
the correct sequence.
5.2
When carrying out the re-torque to the
wheel nuts, under no circumstances should
the wheel nuts be slackened and retightened.
Instead, the wheel nuts should simply be
checked to see if the correct torque is still
applied.
